Artificial Analysis Intelligence Index v5.0

Artificial Analysis Intelligence Index

Artificial Analysis Intelligence Index combines a comprehensive suite of evaluation datasets to assess language model capabilities across reasoning, knowledge, math, and programming.

It is a helpful synthesis of overall language model intelligence and can be used to compare language models. Like all evaluation metrics, it has limitations and may not apply directly to every use case. However, we are confident that it is a more useful synthesis comparison between language models than any other metric in existence today.

Artificial Analysis Intelligence Index v5.0 incorporates 9 evaluations: AA-Briefcase v1.1, AutomationBench-AA, GDP.pdf, FrontierCode 2.0, Terminal-Bench 4.0, AA-Omniscience v1.1, HLE-Diamond, CritPt v2 (Hard Subset), and Terminal-Bench-Science 0.1.0. Our methodology emphasizes fairness and real-world applicability.

The Artificial Analysis Intelligence Index is a primarily text-based, English-language evaluation suite. We benchmark models for image inputs, speech inputs and multilingual performance separately to the Intelligence Index evaluation suite.

Intelligence Index evaluation suite

The Intelligence Index is calculated as a weighted average across four categories: Knowledge Work (25%), Coding (25%), Science (25%), and General (25%). Category membership and per-evaluation weights are shown below.

Intelligence Evaluation Principles

Our evaluation approach is guided by four core principles:

• Standardized: All models are evaluated under identical conditions with consistent prompting strategies, temperature settings, and evaluation criteria.
• Unbiased: We employ evaluation techniques that avoid unfairly penalizing models for answers that correctly follow the instructions in our prompts. This includes using clear prompts, robust answer extraction methods, and flexible answer validation to accommodate valid variations in model outputs.
• Zero-Shot Instruction Prompted: We evaluate using clear instructions without examples or demonstrations, testing models' ability to follow directions without few-shot learning. This approach aligns with modern instruction-tuned and chat style models.
• Transparent: We disclose our methodology, including prompt templates, evaluation criteria, and limitations.

General Testing Parameters

We test all evals with the following settings:

• Temperature: 0 for non-reasoning models, 0.6 for reasoning models (unless another temperature is recommended by the model lab)

• Maximum output tokens:

• Non-reasoning models: 16,384 tokens (adjusted downward where models have a smaller context window, or lower maximum output tokens cap)

• Reasoning models: Maximum output tokens allowed, as disclosed by model creators (custom setting for each reasoning model)

• Error handling:

• Automatic retry on API failures (up to 30 attempts)

• All questions that failed all 30 retries are manually reviewed. Results where persistent API failures have caused issues are not published. Errors where all available APIs for proprietary models block a certain question may lower scores (this effect is not material)

• Scoring methodology: We generally use pass@1 scoring across our evaluations, where a model must produce the correct answer on its first attempt. For evaluations with multiple repeats, pass@1 is calculated by aggregating results across all repeats. This is calculated as:where pi = 1 if attempt i is correct, 0 otherwise, and k is the total number of test instances across all repeats.

We maintain internal copies of all evaluation datasets. The sources of our selected datasets are listed below.

For the Artificial Analysis Intelligence Index evaluations, we use the token counts reported by each model's API provider where available, to accurately report the cost of running the Intelligence Index. In the rare cases where provider token counts are unavailable, we use a canonical-tokenizer fallback. This contrasts with the approach in performance benchmarking, where we use client-side token counts from the o200k_base tokenizer to standardize token counts for the same text across models. When reporting cache hit rates and cost, we combine these token counts with live measurements of the model's typical cache hit rate, rather than relying on the one-off measurement when the evaluation was run.

We use e2b as our primary sandbox provider for agentic benchmarks.

Artificial Analysis Intelligence Index Evaluations

Evaluations that make up the current Artificial Analysis Intelligence Index, grouped by category.

Knowledge Work

AA-Briefcase v1.1

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 15% weighting.
• Description: AA-Briefcase is a new benchmark for testing models on realistic knowledge work tasks in complex projects built by industry experts. Models are evaluated on multi-week knowledge work projects, each with many linked tasks and thousands of input source files. AA-Briefcase combines rubric and pairwise grading to evaluate verifiable task success, analytical quality, and presentation quality, giving a holistic view of overall agentic capability in knowledge work.
• Changes from AA-Briefcase v1: v1.1 changes only how Elo ratings are fitted. We fit the ratings with a Crowd-BT model. For a comparison of submissions and with fitted strengths and , and annotator quality :We define , giving:where is fitted per scope on past AA-Briefcase judgments. Rubric grading is decided by a deterministic comparison rather than a judge, so for that scope. While Elo scores shift, rank ordering is largely preserved.
• Example dataset: https://huggingface.co/datasets/ArtificialAnalysis/AA-Briefcase-Lite
• Agent harness: https://github.com/ArtificialAnalysis/Stirrup
• Implementation:

  • Each AA-Briefcase scenario is a realistic multi-week business problem, organized as a multi-week workflow that the agent works through in sequence, with 2-5 tasks per week. Although tasks within a scenario share files and context across weeks, models currently complete each task in an independent run, without carrying over their own prior submissions. The agent receives the task description and accessible source files, then produces final deliverable files without live interaction or iterative feedback during execution.

  • Scenario source pools include shared files and week-specific files, mixing real, augmented, and synthetic materials. Source files are designed to include realistic professional artifacts such as Slack exports, spreadsheets, PDFs, interview transcripts, market research, standards documents, app-store pages, board materials, emails, and other business records. Later-week tasks may receive standardized base-case files (the same reference work products given to every model), so each task stays independently runnable while preserving continuity across the week.

  • Model submissions are run with Stirrup in a week-scoped E2B sandbox.

    • Turns: Agents run for up to 500 turns per task.
    • Tools: The agent is given a single code-execution tool that runs shell commands and code inside the sandbox, plus the finish tools below (and a view-image tool when the model supports vision). The sandbox has no internet access, so the agent can only use the provided source files.
    • Sandbox: Each scenario/week sandbox is built from that week's source files, with standard Python packages and system tools for document processing and scientific computing pre-installed.
    • Finish tools: A finish tool, which the agent calls to submit a summary and the absolute paths of its deliverables (validated to be actual files, not directories or missing paths), and an abandon_task_finish (give-up) tool, which it calls with a reason only when it concludes the task is genuinely impossible.

  • Prompts: The prompts used across generation and grading:

    • Agent system prompt:

      You are an AI agent working on a specific task within a multi-week simulated workplace scenario. Each task is part of a longer workflow; your job is to complete the current task using the tools provided in up to 500 steps, then submit your deliverables.
      
      When you are done you must call the `finish` tool as your final step, passing a brief summary of what you accomplished and a list of absolute paths for every deliverable file.
      
      If you have genuinely concluded that the task cannot be completed — for example because required inputs are missing, a hard dependency is unavailable, or the request itself is incoherent — call the `abandon_task_finish` tool with a brief reason instead. Do not use it to escape difficulty.
      
      You cannot interact with the user during the task. Record any clarifying assumptions you made in your finish summary.
      

    • Agent task prompt:

      <execution_context>
      ## Sandbox
      
      You operate inside an isolated Linux container through the `code_exec` tool, which runs shell commands and lets you read, create, and edit files. Commands run as the unprivileged user `user` (UID 1000), starting from `/home/user`. Passwordless `sudo` exists but is rarely needed, since your home directory is fully writable.
      
      Every command runs independently: no working directory, environment variable, or other shell state carries over from one call to the next. Prefer absolute paths for both files and commands, and do not navigate with `cd` across calls — a `cd` in one command is gone by the next, so relying on it leaves you silently operating in the wrong place. When a step genuinely needs a different directory, chain it into the same command (e.g. `cd /home/user/work && python build.py`).
      
      ## No network
      
      The container has no outbound connectivity, and there is no proxy, allowlist, or flag that can turn it on — treat the environment as permanently offline. Anything that reaches for the internet will fail, including package installs (`pip`, `npm`, `apt`), remote `git` operations, and any HTTP/HTTPS client request from any language.
      
      Identify a network block by its error signature rather than by guessing: failed name resolution (`Could not resolve host`, `Temporary failure in name resolution`), an unreachable route (`Network is unreachable`, a refused or timed-out connection to a public host), or a stalled TLS handshake. When you see these, the failure is structural — do not retry the same call and do not hunt for a workaround (mirrors, alternate hosts, cached copies). Re-plan using only what is already installed and what ships inside your workspace.
      
      ## Filesystem
      
      - Writable: everything under `/home/user/` plus `/tmp`. Use these for deliverables, intermediate files, and caches.
      - Read-only inputs:
      - `/home/user/shared/` — reference material shared across the whole scenario
      - `/home/user/week/` — documents specific to this week's tasks
      Copy these into a working folder before transforming them rather than editing them in place.
      
      ## Runtime
      
      A broad scientific-computing and document-processing stack is already installed, so confirm what is present before assuming a gap:
      - Python 3.13 with the usual data stack (numpy, pandas, polars, scipy), plotting (matplotlib, plotly), the scikit-learn ML family, and document tooling (python-docx, python-pptx, openpyxl, PyMuPDF, pdfplumber, reportlab, weasyprint, Pillow, opencv), plus Playwright.
      - System tools include LibreOffice, Pandoc, Tesseract, FFmpeg, ImageMagick, Ghostscript, TeX Live, OpenJDK, Chromium, jq, and git.
      - Check availability with `pip show <pkg>` or `which <tool>` instead of installing — installs fail offline, but almost anything you would reach for is already here.
      - matplotlib runs headless (`MPLBACKEND=Agg`): write figures to files; never call `plt.show()`.
      - Commands are terminated after 20 minutes. Keep them bounded, persist intermediate results to disk, and split long jobs into smaller steps.
      
      ## Submitting your work
      
      Finish by calling the `finish` tool — anything not submitted through it is not graded. Your call must include:
      1. A short summary of what you accomplished.
      2. Absolute paths to every deliverable (files only, not folders).
      
      Save each deliverable directly in `/home/user` under the exact filename the task asks for — not in a subdirectory.
      
      Save deliverables as ordinary, visible files. Do not leave the only copy of your work in a dot-prefixed file or directory (e.g. `.submission.txt`, `.outputs/report.md`), including inside an archive; a `.zip` is fine when the task explicitly asks for one. Assume your files will be opened and edited by others after submission, so write them to last.
      
      If the task genuinely cannot be completed, call the `abandon_task_finish` tool with a brief reason instead. Use it only when you have concluded the work is impossible — not to escape a difficult task.
      </execution_context>

    • Binary rubric grading prompt:

      You are grading a submitted deliverable against one binary rubric check.
      
      The user message contains:
      - the task instructions,
      - the rubric item,
      - the submitted artifact content.
      
      Submitted artifacts may appear as text blocks, image blocks, or parser notes for unsupported content.
      
      Use only evidence from the submitted artifact content. Do not infer facts from filenames, task instructions, or rubric text unless the submitted artifact content supports them.
      
      Beyond the task instructions and rubric in the user message, you only ever receive the submitted artifact itself, never the external source files it cites. Do not fail an item merely because you cannot open or cross-check a cited source — judge citations on whether they are present, specific, and well-formed in the submission, not on whether the source's contents can be independently confirmed.
      
      Return a strict binary judgment:
      - passed=true only if the pass criteria are satisfied.
      - passed=false if any required element is missing, materially wrong, unsupported, or not evidenced.
      
      Write concise reasoning that cites submitted artifact evidence or the absence of evidence.
      Do not award partial credit.
      

  • Each task is graded against two styles of checks. Rubric checks are binary pass/fail criteria scored against a single submission. Pairwise checks compare two submissions for the same task and return a preferred submission or tie. There are two kinds: Analytical Quality (which output has deeper, better-structured analysis) and Presentation (which output is more professionally presented).

  • Rubric grading and the analytical-quality and presentation pairwise comparisons each use a panel of three judges rather than a single judge, reducing bias toward submissions from the same model or model family. Rubric grading uses Claude Opus 4.8 at max effort, GPT-5.5 at high reasoning, and Gemini 3.1 Pro Preview at high reasoning. Pairwise comparisons use Claude Opus 5 at high effort, GPT-5.6 Sol at medium reasoning, and Gemini 3.8 Flash at high reasoning. Each rubric verdict and LLM-judged pairwise comparison is decided by one judge sampled from its panel, with sampling balanced across checks and matches. To keep results comparable, a given rubric check is always graded by the same judge. AA-Briefcase Elo is the headline metric of this evaluation: it aggregates analytical quality Elo, presentation Elo, and rubric pass rate, with rubric performance converted into Elo via synthetic head-to-head matches using a maximum-likelihood Elo aggregation. Each scope is fitted with a Crowd-BT model.

  • Intelligence Index Integration: For inclusion in the Intelligence Index, the combined AA-Briefcase v1.1 Elo is frozen at the time of a model's addition and normalized as clamp((Elo - 500) / 2000). The Elo scale is anchored to GPT-5.5 (medium) at 1000, while the fixed normalization range preserves stable Intelligence Index contributions over time. Artificial Analysis may update the reference parameters as models progress against the evaluation, to maintain meaningful differentiation in the Intelligence Index.

AutomationBench-AA

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 5% weighting.
• Description: AutomationBench-AA is Artificial Analysis' run of Zapier's AutomationBench. It tests whether models can complete realistic SaaS workflows that span multiple simulated business apps, using REST APIs as the tool interface.
• Paper: https://arxiv.org/abs/2604.18934
• Leaderboard: https://zapier.com/benchmarks
• Repository: https://github.com/zapier/AutomationBench
• Dataset:
  • We evaluate a private 657-task held-out split from AutomationBench dataset version 1.0.6
  • The tasks cover six business domains: Finance, HR, Marketing, Operations, Sales, and Support
  • They run in simulated app environments that include products such as Gmail, Google Sheets, Slack, Salesforce, Zendesk, Jira, and HubSpot
• Implementation:
  • We run each task once in the AutomationBench multi-turn environment, with a 50-turn cap. Models use the API toolset, discovering and calling the REST endpoints they need through structured tool calls
  • We classify each AutomationBench assertion as either an objective, which must be made true by the agent, or a guardrail, which initially passes and must not be broken by the agent
  • Objectives and guardrails are graded using programmatic checks on the final environment state. AutomationBench-AA does not use a separate LLM judge for grading
  • For the headline score, a task receives 0 if the model violates any guardrail. If no guardrails are violated, the task receives the percentage of objectives the model completed. Errored tasks also score 0
  • Each task belongs to one business domain, so domain breakdowns are mutually exclusive subsets of the task set. App breakdowns are not mutually exclusive: a task can involve multiple apps, so its objective and guardrail assertions may contribute to more than one app

GDP.pdf

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 5% weighting.

• Description: Artificial Analysis' implementation of Surge AI's GDP.pdf, a benchmark that tests whether models can reason over long, real-world professional documents and satisfy task-specific criteria.

• Paper: https://arxiv.org/abs/2607.11192

• Dataset: surgeai/GDP.pdf

• Evaluation set: 100 tasks across ten professional domains, grounded in 4,592 PDF pages and graded against 1,275 criteria. We attempt every task five times, so each model has a fixed denominator of 500 attempts.

• Document preparation and delivery: We prepare each source PDF with LiteParse 2.5.0, with English OCR enabled. Every model receives the complete extracted text of every page. When supported by the endpoint, we send page images first in page order, followed by the task and complete extracted text in a single user message. Models without image input receive text alone. We render page images at 150 DPI and reduce them, to a 72 DPI minimum, when model context or provider payload limits require it. We may also convert opaque pages from PNG to JPEG. Where an endpoint caps how many images one request may carry, we combine pages into composite images, two pages per image first and up to four where the cap is tighter, each cell labeled with its page number. Past four pages per image, images cover the leading pages only; the remaining pages remain in the extracted text. When either applies, the prompt tells the model that page images are composites and the page number where image coverage stops. If the images cannot fit within context or request-size limits after adaptation, we send the complete extracted text alone. We do not truncate or summarize the extracted text. Models answer in a single turn without browsing or tools.

  Unlike the Surge AI implementation, we do not use API document input features. These are opaque to the user and sit above the model layer, so they can introduce variation from API product decisions and hosts rather than comparing models apples-to-apples.

• Judging: GPT-5.6 Luna (medium) judges each criterion independently. Each call receives the task prompt, contestant answer, and one criterion, but not the source PDF or contestant identity. We accept a task grading only when every criterion has a verdict. We score errors, missing attempts, and terminal input failures as zero.

• Reported metrics:

  • All-pass is the headline metric: the share of all 500 attempts where every criterion passes.
  • Mean Pass is the secondary metric: we compute each attempt's criterion pass rate, then average it with equal weight across tasks and repeats.
  • Domain cuts use the same task-macro Mean Pass calculation. We do not report domain All-pass.

• Cost and speed scope: Published costs cover contestant model calls only and exclude judge calls, PDF preparation, and OCR. We estimate time per task from output-token usage and model output speed. It excludes judge calls, PDF preparation, and OCR, so it is not an end-to-end evaluation timing.

Differences from the Surge AI implementation

	Artificial Analysis	Surge AI
Document input	Text extracted with LiteParse and OCR, plus page images for image-capable models	Raw PDF sent to the provider's document input
Judge	GPT-5.6 Luna (medium)	Gemini 3.5 Flash

The task set is shared, but the document input and judge differ, so Artificial Analysis and Surge scores are not directly comparable.

Coding

Terminal-Bench 4.0

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 10% weighting.
• Description: The 4.0 release of Terminal-Bench, developed by Stanford University researchers, the Laude Institute, and the open source community. Covers software engineering, system administration, data processing, model training, and security, with each task graded by its own verification suite.
• Leaderboard: https://www.tbench.ai/?version=4
• Dataset: https://github.com/harbor-framework/terminal-bench
• Implementation:
  • We evaluate the full Terminal-Bench 4.0 dataset (66 tasks) using the mini-swe-agent harness, with pass@1 scoring averaged over 3 repeats per task
  • Each task has its own set of tests. We follow the Terminal-Bench methodology: a task passes only if every test passes, grading runs in each task's own separate verifier container isolated from the agent's environment, and a verifier that exceeds its timeout counts as a failure
  • We apply the following constraints on evaluations for the agent:
    • Maximum agent steps are limited to 500
    • Task timeouts and sandbox resources follow the upstream task definitions
  • All other agent configuration follows mini-swe-agent defaults, including the interactive mini config and prompts, the native bash tool, and no context compaction or summarization: the agent always sees its full transcript

FrontierCode 2.0

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 15% weighting.
• Description: FrontierCode 2.0 is a coding benchmark from Cognition, built with maintainers of open-source repositories. Each task asks an agent to make a change to a real open-source repository, and the benchmark measures whether the change is good enough for a maintainer to merge. The benchmark grades each change with held-out tests and a rubric of blocking and non-blocking criteria.
• Announcement: https://cognition.com/blog/frontier-code-2.0
• Implementation:
  • We evaluate all 132 tasks with 3 attempts per task
  • We run the agent in our Stirrup harness. Shell commands keep running in the background after the agent starts them. The agent can check a command's output, or stop it, in a later turn
  • The FrontierCode verifier grades each attempt with the task's tests and rubric. We use GPT-6 Luna (medium) as the LLM judge
  • An attempt that fails any blocking check, or that the trajectory scanner flags for looking up the solution, scores 0. Other attempts get a weighted score across the rubric's criteria. We average each task's attempts, then average the task scores with equal weight
  • We apply the following constraints on evaluations for the agent:
    • We cap the agent at 500 turns
    • Each attempt has a wall-clock limit. If the agent reaches it, we grade the repository as the agent left it

Science

CritPt v2 (Hard Subset)

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 10% weighting.
• Description: The hard subset of CritPt v2 is a fixed, private list of 40 of the 70 CritPt problems, selected to remove the 30 problems that seven frontier models solved in all five attempts at the time CritPt v2 was launched.
• Implementation: We run and grade all 70 problems as described for CritPt v2, then report mean accuracy across repeats (pass@1) on the 40 problems in the hard subset.

Terminal-Bench-Science 0.1

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 15% weighting.
• Description: Terminal-Bench-Science is an open academic collaboration developed by Stanford University researchers with the Terminal-Bench and Harbor team, and includes contributions from scientists at institutions across the globe. Its research workflow tasks are drawn from real scientific practice, and experts curate and review each one. Each task has its own set of tests that the agent must pass by working in a terminal. The 0.1.0 release covers the life, physical, mathematical, engineering, and earth sciences.
• Citation: https://doi.org/10.5281/zenodo.22110254
• Leaderboard: https://terminal-bench-science.ai/
• Dataset: https://github.com/harbor-framework/terminal-bench-science
• Implementation:
  • We evaluate the full Terminal-Bench-Science 0.1.0 release (70 tasks: 19 life sciences, 17 physical sciences, 17 mathematical sciences, 9 engineering sciences, 8 earth sciences) using the mini-swe-agent harness, with pass@1 scoring averaged over 3 repeats per task
  • Each task has its own set of tests. A task passes only if every test passes, and grading runs in each task's own separate verifier container isolated from the agent's environment
  • We apply the following constraints on evaluations for the agent:
    • We cap the agent at 1,000 steps
    • Task timeouts and sandbox resources follow the upstream task definitions
  • All other agent configuration follows mini-swe-agent defaults, including a 30-second timeout on each shell command, so longer computations must run in the background

General

AA-Omniscience v1.1

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 15% weighting.
• Description: AA-Omniscience is a knowledge and hallucination benchmark that measures factual reliability, rewards precise knowledge, and penalizes incorrect guesses or hallucinations. It provides a detailed assessment of a model’s ability to distinguish known from unknowns across diverse knowledge domains.
• Changes from AA-Omniscience v1: The AA-Omniscience v1.1 dataset has 3,000 questions, down from 6,000 in the original AA-Omniscience dataset. We filtered out saturated questions, removed the 600 questions published in the v1 public set, added new questions, and updated questions that were ambiguous or had errors. Scores are not directly comparable with v1.
• Paper: https://arxiv.org/abs/2511.13029
• Dataset: https://huggingface.co/datasets/ArtificialAnalysis/AA-Omniscience-Public-v1.1
• Implementation:
  • The benchmark consists of 3,000 questions covering 42 topics, including Business, Humanities and Social Sciences, Health, Law, Software Engineering, and Science, Engineering and Mathematics.
  • Models are scored using the AA-Omniscience Index, which assigns points for correct answers, subtracts points for hallucinated responses, and keeps abstentions neutral, rewarding abstentions over incorrect guesses
  • Each answer is graded as either CORRECT, INCORRECT, PARTIAL_ANSWER, or NOT_ATTEMPTED based on the model's response and the ground truth answer. GPT-5.6 Luna (medium) is used as the grading model
  • Intelligence Index Integration: AA-Omniscience contributes two components to the Intelligence Index: (1) Accuracy - the proportion of correct answers, weighted at 10% of the overall Index, and (2) Non-Hallucination Rate - calculated as 1 minus the hallucination rate, weighted at 5% of the overall Index (AA-Omniscience's 15% share).

HLE-Diamond

• Status: Included in Artificial Analysis Intelligence Index v5.0 at 10% weighting.
• Description: HLE-Diamond is a refined and updated 1,000-question version of Humanity's Last Exam from the Center for AI Safety and Scale AI. The authors built it through a process of cleaning and refining the original questions with input from research communities. They split the questions evenly into 500 reasoning questions and 500 knowledge questions.
• Announcement: https://lastexam.ai/blog/hle-diamond
• Dataset: https://huggingface.co/datasets/cais/hle-diamond
• Repository: https://github.com/centerforaisafety/hle
• Implementation:
  • We evaluate all 1,000 questions without tools. We use our own implementation, which follows the official HLE evaluation scripts. Every question uses the official HLE system prompt, which asks for an explanation, an answer, and a confidence score
  • Models that accept image input receive the image after the question text, downscaled only where a provider's image size limit requires it. Models without image input receive only the question text for the 272 image questions, and we grade them on all 1,000 questions
  • We grade each answer with the official HLE judge prompt and response format, using GPT-5.6 Luna (medium) as the judge, with pass@1 scoring. We report the overall score and the score on each partition
  • Our Humanity's Last Exam evaluation uses the 2,158 text-only questions from the full HLE dataset. HLE-Diamond uses a refined 1,000-question subset that includes 272 image questions, so scores on the two are not directly comparable

Knowledge Work

GDPval-AA v2.1

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0). GDPval-AA was removed from the Intelligence Index in v5.0, having been a constituent up to and including v4.3.2.

• Description: GDPval-AA v2.1 is Artificial Analysis' evaluation framework for OpenAI's GDPval dataset. It assesses language models' capabilities on economically valuable tasks, covering 44 occupations across key sectors contributing to GDP in the United States.

• Changes from GDPval-AA v2: v2.1 changes only how the Elo scale is fixed:

  • We anchor the scale by pinning DeepSeek V4.1 Flash (max) at 1600.
  • We fit the ratings with a Crowd-BT model. For a comparison of submissions and with fitted strengths and , and annotator quality :We define , giving:where is fitted on past GDPval-AA judgments.
  • While Elo scores shift, rank ordering is largely preserved.

• Paper: https://arxiv.org/abs/2510.04374

• Agent harness: https://github.com/ArtificialAnalysis/Stirrup

• Dataset:

  • We base our evaluation on the public gold OpenAI GDPval dataset from https://huggingface.co/datasets/openai/gdpval
  • Some Microsoft Office files in the dataset had missing metadata parts or malformed relationship entries that prevented LibreOffice from opening them. We added the minimal missing metadata and fixed the malformed entries to ensure compatibility. Document body, slide content, and layout were not changed.

• Implementation: This evaluation comprises two stages:

  • Task Submission – Models are given a task and required to produce one or more files.
  • Pairwise Grading – A judge sampled from a panel of three frontier LLM judges blindly ranks two submissions for the same task, each created by a different model.
  • Elo Calculation: After collecting pairwise rankings, we fit them to a Crowd-BT model via maximum likelihood estimation, and compute confidence intervals using the sandwich estimator to establish our final Elo metric. We anchor the Elo scale by pinning DeepSeek V4.1 Flash (max) at 1600. Every other rating is fitted relative to that anchor.

• Task Submission Details:

  • All models are run using our open source agentic harness, Stirrup. Within the harness, models are given a code execution environment (E2B sandbox), and the following six tools to call at their discretion:

    • Web Fetch – Fetches and extracts main content from a web page as markdown.
    • Web Search – Searches the web using Brave Search API; returns the top 5 results with title, URL, and description.
    • View Image – Reads and displays image files (.png, .jpg, .jpeg) from the sandbox as native image tokens for LLM consumption. This tool is only exposed to models with vision support. Images are downscaled to a maximum of 1 megapixel before being sent to the model.
    • Code Exec – Executes bash commands in the sandbox via the code_exec tool; returns exit code, stdout, and stderr.
    • Finish – Signals task completion and specifies which files to submit.
    • Abandon Task – Signals that the model does not believe it can complete the task, with a brief reason, instead of submitting files.

  • For each task, a new E2B sandbox is initialized with the reference files associated with the given task and pre-installed with a range of relevant packages for the task set. We based the package collection on the disclosed environment from the original GDPval paper, expanded in v2 with additional dependencies (including a full TeX Live LaTeX toolchain and build tools).

    System packages are the full pinned transitive closure resolved inside the Debian trixie base image, so most entries are dependencies of the packages we install directly

  • We prompt the agent with an instruction interpolating the relevant task prompt, reference files, and finish tool details.

• Execution Limits:

  • The LLM is given 250 turns to complete the task. A single turn is defined as an assistant message and its tool calls (if any). As the model approaches the limit, it is notified of its remaining turn budget.
  • The model may end the run early via the Abandon Task tool where it does not believe it can complete the task, providing a brief reason instead of submitting files.
  • If the model exceeds 70% of its context window after completing a given turn, the agent asks it to summarize task state, completed work, current files, remaining steps, and important context, then clears earlier turn history while retaining the task prompt and the summary for continuation.

Task Submission System Prompt:

You are an AI agent completing a standalone professional task. Your job is to use the provided tools to produce the requested deliverables within 250 steps, then submit your work.

When you are done, call the `finish` tool as your final step with:
1. A brief summary of what you accomplished.
2. Absolute paths to every deliverable file.

If you have genuinely concluded that the task cannot be completed because required inputs are missing, a hard dependency is unavailable, or the request is incoherent, call the `abandon_task_finish` tool with a brief reason instead. Do not use it to escape difficulty.

You cannot interact with the user during the task. Make reasonable assumptions when needed and record them in your finish summary.

Task Submission Prompt:

## Runtime

You are running in an isolated Linux sandbox. Use the `code_exec` tool to read, create, and modify files. Commands run as the non-root user `user` (UID 1000). Default working directory is `/home/user`.

Every command runs independently: no working directory, environment variable, or other shell state carries over from one call to the next. Prefer absolute paths for both files and commands, and do not navigate with `cd` across calls — a `cd` in one command is gone by the next, so relying on it leaves you silently operating in the wrong place. When a step genuinely needs a different directory, chain it into the same command (e.g. `cd /home/user/work && python build.py`).

A broad scientific-computing and document-processing stack is already installed, so confirm what is present before assuming a gap:
- Python 3.13 with the usual data stack (numpy, pandas, polars, scipy), plotting (matplotlib, plotly), the scikit-learn ML family, and document tooling (python-docx, python-pptx, openpyxl, PyMuPDF, pdfplumber, reportlab, weasyprint, Pillow, opencv), plus Playwright.
- System tools include LibreOffice, Pandoc, Tesseract, FFmpeg, ImageMagick, Ghostscript, TeX Live, OpenJDK, Chromium, jq, and git.
- Commands are terminated after 10 minutes. Keep them bounded, persist intermediate results to disk, and split long jobs into smaller steps.

## Reference Files Location

(This section appears only when the task includes reference files.)

The reference files for the task are available in your environment's file system.

Here are their paths:

- [absolute path to each reference file]

## Completing Your Work

In order to complete the task you must use the `finish` tool to submit your work. If you do not use the `finish` tool you will fail this task!

As a last resort if you really cannot make any meaningful progress, use `abandon_task_finish` with a brief reason instead of submitting files.

**Required in your finish call:**
1. A brief summary of what you accomplished
2. A list of **ABSOLUTE file paths** for the required output files (Do not submit folders).

## Task

Here is the task you need to complete:

[task description]

Please begin working on the task now.

• Context Overflow: If the next model call (or the summarization request itself) exceeds the context window, the agent keeps unwinding earlier turns until summarization succeeds.
• Task Completion: To complete the task, the LLM must call the finish tool, providing a summary of the work done and the paths of the files it intends to submit. This tool can be used at any turn.
• Grading: We sample pairwise matches between model submissions in two stages:
  • Balanced sampling: We first sample each model diversely, balancing exposure across tasks, judges, and opponents, to seed initial ratings.
  • Active sampling: After the initial phase, we transition to Elo-informed sampling that prioritizes pairings between models with similar ratings to derive the most information per comparison. We maintain balanced exposure of tasks within each model throughout the process.
  • Submissions are randomly anonymized as Submission A and B to mitigate any model or position bias from the grader model.
  • Matches are graded by a panel of three frontier LLM judges from leading labs, each run at its default reasoning settings: GPT-5.6 Sol (medium reasoning), Gemini 3.8 Flash (high reasoning), and Claude Opus 5 (high effort). We sample between the judges for each comparison. The initial task, all reference files, and all submission files are parsed and provided as context to the judge.
  • Document-based files (.pdf, .docx, .pptx, .xlsx, etc.) are parsed as both text and as images. We extract .zip files and parse each individual file separately. For tasks containing audio or video files, the comparison is routed to Gemini 3.8 Flash, which handles these modalities natively. This context is embedded in a grading prompt that asks the judge to determine which of Submission A and B better responds to the task.
  • Final Scoring: Our final Elo score is a Bradley-Terry rating computed via maximum likelihood estimation from all pairwise comparisons (ties counted as half-wins for each side), anchored to DeepSeek V4.1 Flash (max) at 1600. The 95% confidence intervals are computed using the sandwich estimator to quantify rating uncertainty.

Harvey LAB-AA v1.1

• Description: Harvey LAB-AA is Artificial Analysis' implementation of Harvey's Legal Agent Benchmark (LAB), run on Harvey's dataset of 120 private tasks across 24 legal practice areas. For each task the agent reads the case documents in a sandbox and produces legal deliverables - memos, disclosure schedules, deposition summaries, redlines, and similar work products - in a single run without live interaction. A panel of three LLM judges then grades the deliverables criterion-by-criterion against a task-specific rubric of atomic, binary pass/fail criteria.
• What changed in v1.1: v1.1 supersedes v1.0, and scores are not comparable across the two versions. We built this update in collaboration with Harvey. In human preference studies run by Harvey, human experts flagged hallucinations as a primary determining factor in which of two otherwise comprehensive responses they prefer. v1.1 runs on Harvey's latest private dataset (v1.1.0), which includes improvements to the tasks and criteria. It checks every deliverable against the task's source documents for hallucinations, grades each criterion with a three-judge panel, and moves the headline from the Criterion Pass Rate to the Hallucination-Gated All-Pass Rate.
• Example dataset: The five public example tasks shown in the explorer are drawn from Harvey's public examples at https://github.com/harveyai/harvey-labs. The headline numbers are produced on Harvey's private 120-task dataset, which is not publicly released.
• Implementation:
  • Harness: we run all models on our open source agentic harness, Stirrup.
    • Turns: Agents run for up to 200 turns per task.
    • Tools: Within the harness, models get a sandboxed code execution environment, and vision-capable models also get an image viewer tool that reads image files from the sandbox as native image tokens. The sandbox has no internet access, so the agent can only use the provided input documents and the software pre-installed in the image.
    • Sandbox: Each task runs in an isolated Linux sandbox built from a shared agent-evals base image (Debian + Python 3.13), with document-processing tooling such as Pandoc, poppler/pdftotext, LibreOffice, python-docx, python-pptx, openpyxl, pdfplumber, PyMuPDF, and markitdown pre-installed. We stage the task's input documents read-only at runtime, and terminate individual shell commands after 20 minutes.
    • Finish tools: A finish tool, which the agent calls to submit a summary and the absolute paths of its deliverables (validated to be actual files, not directories or missing paths), and an abandon_task_finish (give-up) tool, which it calls with a reason only when it concludes the task is genuinely impossible.
  • Metrics: we report four (the Hallucination-Gated All-Pass Rate is the headline shown across the site):
    • Criterion Pass Rate: the share of atomic pass/fail rubric criteria the deliverables satisfy, averaged across the three judges and pooled over all criteria before the hallucination gate. We plot this raw rubric score against material hallucinations per task to compare rubric coverage and grounding.
    • Hallucination-Gated All-Pass Rate: the share of judges finding every criterion passed with no partial credit, averaged over tasks. Gated means a task with at least one material hallucination counts as zero however well it scored on the rubric. Broken out by practice area it rests on the five tasks in that area, so with three judges a per-area value can only move in steps of 1/15.
    • Hallucination-Gated Near-Pass Rate: the same measure allowing one, and then two, missed criteria. All-pass scores a deliverable that missed one criterion the same as one that missed every criterion; the bands show how close the near misses came. We count criteria missed rather than a percentage of the rubric, because rubrics run 44 to 90 criteria per task (median 55), so the allowance behind a percentage band would vary from task to task.
    • Hallucinations per Task: the mean number of upheld hallucination flags per task, over the tasks the check ran on, reported for material and minor severity separately. Only material flags gate the headline; minor flags are reported but never scored.
  • Hallucination check: alongside the rubric, we audit every submitted deliverable of every task the check runs on.
    • What it measures: contradictions of source documents, content attributed to sources that doesn't exist in them, and specific claims about the matter with no basis anywhere in the record. It doesn't test legal correctness: citations to case law, statutes or doctrine are out of scope.
    • How it runs: a two-stage judge pipeline over the deliverable. A lister judge lists candidate false assertions and quotes as evidence. A skeptic judge then re-examines each flag against the same record and upholds, dismisses or merges each one, re-grading its severity. The skeptic dismisses anything that sits outside the scope of our checks and exists as a blocker to each initial flag, erring toward reasonably conservative scope. We selected it after comparing alternative checkers, including the ablation described in our v1.1 launch article, and found GPT-6 Sol (high) effective at finding material hallucinations of the models compared.
  • Differences from Harvey's benchmark: Harvey LAB-AA is Artificial Analysis' implementation of LAB, built in collaboration with Harvey for v1.1. Our numbers are not directly comparable to Harvey's published results because the evaluation setup differs:
    • Filename matching: we require submissions to match the exact filename in the task instructions. A near-miss filename counts as not produced, which is stricter than Harvey's best-effort matching and can lower our scores relative to theirs.
    • Partial submissions: a criterion fails outright, without reaching the judge, only when none of its deliverables were produced. We still judge partial submissions, where some of the criterion's declared files are present, marking any missing file absent.
    • Judging: a three-judge panel - GPT-6 Sol (medium), Grok 4.7 (medium), and Claude Opus 5.5 (medium) - grades every criterion, where Harvey uses a single judge. We checked the panel for self-preference toward each judge's own model family and found minimal bias, but we include all 3 and average the judges to mitigate any remaining bias. Each criterion scores the share of judges that passed it (0, 1/3, 2/3 or 1). The model-level Criterion Pass Rate is a micro average, pooled over every criterion in every task so longer rubrics weigh more, as in Harvey's own scoring; the all-pass and Hallucination-Gated All-Pass Rates are macro averages, with each task counting equally.
    • Context compaction: Stirrup compacts the agent's context when it runs long, where Harvey ran none.
    • Redlines: we instruct agents to author redlines as real Word tracked changes (w:ins/w:del), and we do not supply Harvey's helper script for producing them.
    • Failed runs: abandoned tasks, runs that hit the turn limit, and empty or unreadable submissions score zero on every rubric metric and are excluded from Hallucinations per Task.
    • Judge context: our judge sees the full task instructions, where Harvey's sees only the task title.
    • Sampling: Harvey runs at temperature 0. We generate at our standard temperatures (0 for non-reasoning models, 0.6 for reasoning models unless the lab recommends another), and each judge runs at its model's standard setting.
    • Tracked changes: the hallucination check audits the accepted text of each .docx, not the tracked-changes render the rubric judges read.
    • Agent skills: Harvey's original implementation equips the agent with custom tools and document-generation skill scripts (for example, for producing .docx, .xlsx, and .pptx files). We do not provide these, so agents produce these files with the general tooling in the sandbox.
  • Prompts: the agent and rubric grading prompts, used verbatim:

    • Agent system prompt:

      You are an AI agent completing a professional legal-work task. Use the tools provided to read the input documents, produce the requested deliverable files, and submit them within {max_turns} steps.
      
      When you are done you must call the `{finish_tool_name}` tool as your final step, passing a brief summary of what you accomplished and a list of absolute paths for every deliverable file.
      
      If you have genuinely concluded that the task cannot be completed - for example because required inputs are missing or a hard dependency is unavailable - call the `{abandon_task_finish}` tool with a brief reason instead. Do not use it to escape difficulty.
      
      You cannot interact with the user during the task. Make reasonable assumptions when needed and record them in your finish summary.
      

    • Agent task prompt:

      <execution_context>
      ## Sandbox
      
      You operate inside an isolated Linux sandbox through the `code_exec` tool, which runs shell commands and lets you read, create, and edit files. Commands run as the unprivileged user `user` (UID 1000).
      
      Files you write persist on disk across calls, but **shell state does not**: each command runs in a fresh shell, so no working directory, environment variable, or other shell state carries from one call to the next. Always use absolute paths for files, and do not navigate with `cd` across calls - a `cd` in one command is gone by the next. When a step genuinely needs a different directory, chain it into the same command (e.g. `cd /home/user && python build.py`).
      
      ## No network
      
      The sandbox has no outbound connectivity, and there is no proxy, allowlist, or flag that turns it on - treat it as permanently offline. Anything that reaches the internet will fail: package installs (`pip`, `npm`, `apt`), remote `git`, and any HTTP/HTTPS request.
      
      Recognise a network block by its error signature - failed name resolution (`Could not resolve host`, `Temporary failure in name resolution`), an unreachable route (`Network is unreachable`), or a stalled connection - rather than guessing. When you see these the failure is structural: do not retry the same call or hunt for a workaround (mirrors, alternate hosts, cached copies). Re-plan using only what is already installed and the files in your workspace.
      
      ## Filesystem
      
      - Writable: everything under `/home/user/` plus `/tmp`. Use these for deliverables, intermediate files, and caches.
      - Read-only inputs: `/home/user/documents` - the task's input documents. Copy these into a working folder before transforming them rather than editing them in place.
      
      ## Runtime
      
      A document-processing stack is already installed - check what is present before assuming a gap:
      
      - **Reading inputs**: `pandoc` or `python3 -c "import docx; ..."` for Word; `pdftotext` or `python3 -c "import pdfplumber; ..."` for PDFs; `python3 -c "import openpyxl; ..."` for Excel; `markitdown <path>` as a general-purpose extractor for .docx, .xlsx, .pptx, and .pdf. `libreoffice` (the `soffice` binary) is also installed - use `soffice --headless --convert-to pdf <path>` to convert any Office format (.docx/.xlsx/.pptx, including legacy .doc/.xls) when the python parsers fall short.
      - **Producing deliverables**:
        - `.docx`: `python3 -c "from docx import Document; ..."` or `pandoc -o out.docx`. For redline deliverables, represent changes as real Word tracked changes (`w:ins`/`w:del` revision elements in the document XML), not simulated with strikethrough or colored formatting.
        - `.xlsx`: `python3 -c "import openpyxl; ..."`.
        - `.md` and other plain text: write directly with `cat`/`tee`/your script.
      - Check availability with `pip show <pkg>` or `which <tool>` rather than installing - installs fail offline, but the document stack above is already present.
      - Commands are terminated after {command_timeout_minutes} minutes. Keep them bounded, persist intermediate results to disk, and split long jobs into smaller steps.
      
      ## Submitting your work
      
      Finish by calling the `{finish_tool_name}` tool - anything not submitted through it is not graded. Your call must include:
      1. A short summary of what you accomplished.
      2. Absolute paths to every deliverable (files only, not folders).
      
      Save each deliverable directly in `/home/user` under the exact filename the task asks for - not in a subdirectory. Save deliverables as ordinary, visible files - do not leave the only copy of your work in a dot-prefixed file or directory (e.g. `.report.docx`, `.output/report.docx`). Assume your files will be opened and edited by others after submission.
      
      If the task genuinely cannot be completed, call the `{abandon_task_finish}` tool with a brief reason instead. Use it only when you have concluded the work is impossible - not to escape a difficult task.

      </match_criteria>
      </criterion>
      
      Return `pass` only if the work product satisfies the criterion as described; otherwise `fail`.
      

    • Judge criteria prompt:

      You are given {criterion_count} independent binary criteria to evaluate against the work product above. Judge each criterion separately, strictly on its own merits - a verdict on one criterion must not influence any other.
      
      {criteria_block}
      
      These criteria are a subset of the task's rubric, and their ids are deliberately not consecutive - the rest are graded elsewhere. Grade only the ids listed above, and never return a verdict for an id that does not appear in that list, even where it would continue the sequence.
      
      Return one verdict object per criterion, keyed by that criterion's id. Every id listed below is a required key and no other key may appear. For each criterion, return `pass` only if the work product satisfies it as described; otherwise `fail`.
      
      Required ids ({criterion_count}): {criterion_ids}
      

APEX-Agents-AA

• Description: APEX-Agents-AA is Artificial Analysis' independent implementation of Mercor's APEX-Agents benchmark. It evaluates long-horizon, cross-application agent work in professional services environments spanning investment banking, management consulting, and law.
• Paper: https://arxiv.org/abs/2601.14242
• Dataset:
  • We base our evaluation on the public APEX-Agents dataset from https://huggingface.co/datasets/mercor/apex-agents
  • We evaluate 452 tasks from the public 480-task release (excluding Investment Banking Worlds 244 and 246, which have external runtime dependencies)
• Implementation:
  • Each task is run with 3 repeats and scored using pass@1 - a repeat passes only if all rubric items are satisfied, and the leaderboard score is the average pass rate across repeats
  • All models are run using our open source agentic harness, Stirrup, with a 200-turn cap per task
  • Agents operate inside the Archipelago environment and access workplace tools through MCP servers exposed by its gateway
  • The agent starts with a small meta-tool toolbelt and must explicitly manage MCP-backed tools using:
    • List Tools – Shows which tools are currently available
    • Inspect Tool – Inspects a tool before adding it
    • Add Tool – Makes an MCP-backed tool available to the agent
    • Remove Tool – Removes tools that are no longer needed
  • The agent also receives:
    • Todo Write - Creates or updates the agent's todo list. It can either replace the full list or merge updates by todo ID, and all todos must be completed or cancelled before final submission is accepted
    • Finish - Submits the agent's final answer together with a completion status. It is the only way to submit a final answer, and only a completed Finish submission proceeds to grading
  • MCP tool calls have a 60-second timeout. Tool outputs are truncated when needed to a 24k-token budget using a 20k-character head and 5k-character tail excerpt. Image inputs are compressed to approximately 1 MP before being returned to the model
  • Grading is run locally with the Archipelago local file grader. Each repeat is graded against the task rubric using both the final answer submitted through Finish and the filesystem diff between initial and final world snapshots. A repeat passes only if every rubric item is satisfied. Gemini 3 Flash with 'low' reasoning is used as the LLM judge

AA-AnalystAgent

• Description: AA-AnalystAgent is Artificial Analysis' end-to-end data analysis benchmark. An agent answers quantitative questions across business and scientific domains, working from the supplied source spreadsheets and documents as primary inputs and executing Python in a sandboxed code-execution environment. AA-AnalystAgent is reported as a standalone leaderboard and is not a component of the Artificial Analysis Intelligence Index.
• Agent harness: https://github.com/ArtificialAnalysis/Stirrup
• Dataset:
  • AA-AnalystAgent is a privately held benchmark; the question set, reference answers, and source files are not publicly released, to limit contamination risk
  • 80 quantitative questions across 14 business and scientific domains, including environmental reporting, trade and commodity statistics, healthcare expenditure reports, hydrology and weather data, government appropriations, energy cost models, financial models, and project schedules
  • Questions span five functional workflow archetypes covering the spread of real analyst work: source lookup and diagnosis, filter and total, ratios, trends and sensitivities, P&L modeling, and cash, balance-sheet and valuation modeling
  • Each question is paired with a folder of reference spreadsheets and documents (xlsx, docx) that is uploaded into the agent's workspace. A human-authored reference answer is held out from the agent and used by the grader at scoring time
  • Reference answers are independently validated by Artificial Analysis
• Implementation:
  • Each question is run with 5 independent repeats. The leaderboard score is pass^5 (the share of questions answered correctly on every one of the 5 attempts):where pji = 1 if attempt i on question j is correct, 0 otherwise, and n is the number of questions. This departs from the pass@1 scoring we use across our other evaluations: an analyst agent is only useful if its answers hold up without re-checking, so the headline metric rewards reproducing a correct answer over reaching it occasionally
  • Alongside pass^5 we compute pass@1 (the mean pass rate per attempt, aggregated across all repeats) and pass@5 (the share of questions solved on at least one attempt), which separate a model's reliability from its ceiling
  • All models are run as agents using our open source agentic harness, Stirrup, with a 100-turn cap per task
  • The agent is provided a small toolset covering code execution in an isolated Linux sandbox (Python 3.12 with the question's reference files mounted and a pinned set of standard Python data analysis libraries preinstalled), URL fetching, image viewing for vision-capable models, and final-answer submission. Models are instructed to submit only the answer value (e.g. just the number or label), without explanation
  • Each response is graded binary correct or incorrect against the held-out reference answer. Every cell is sent to an LLM judge so grading artifacts and judge-cost accounting stay uniform. A deterministic numeric equivalence pre-check then overrides the judge on unambiguous cases: an answer equal to the reference value, in the same unit convention, at the precision the question asks for, is a guaranteed pass. The pre-check is one-sided (it never fails an answer), so everything it cannot settle keeps the judge verdict. If the judge returns a malformed response on a cell the pre-check can settle, the pre-check still records a pass. Gemini 3 Flash (Reasoning) is used as the LLM judge

Agent Prompt: The agent is prompted with the following template, interpolating the question's reference files, the task, and the finish tool name:

You are tasked with answering a data analysis question.

## Environment

The `code_exec` tool provides access to a Linux-based execution environment with a full file system where you can create, read, and modify files.

Python 3.12 is the default runtime. Use `python script.py` to run scripts.

{reference_files}
</reference_files>

## Task

<task>
{task}
</task>

## Submitting Your Answer

When you have determined the answer, use the `{finish_tool_name}` tool to submit it.
Your answer should be a concise, direct response to the question.
If the question asks for a number, provide just the number.
If the question asks for a name or label, provide just that.
Do NOT include explanations in your answer — only the final answer value.

Grader Prompt: Every (model, question) response is sent to an LLM judge with the following prompt, interpolating the original question, the held-out reference answer, and the agent's submitted answer. The numeric pre-check may then override that verdict as described above:

You are an expert evaluator grading a data analyst's response to a question.

Decide whether the response is correct or incorrect, judged against the reference answer and the standard a professional data analyst working in this question's domain would be held to. Focus on the substance of the answer, not prose style. Be objective and consistent, and give a brief explanation for your verdict.

First identify exactly what the reference requires — the specific value(s), item(s), or label(s) — and what the response actually commits to, then compare them directly before deciding.

Apply these conventions:

- Format directives are binding. If the question specifies a form or precision — a number of decimal places, "as a percentage", "to the nearest cent", a cell reference, particular units — the response must satisfy it. A right value in the wrong requested form is incorrect.
- Equivalent representations of the same value are correct. Thousands separators, currency symbols, surrounding whitespace, and trailing zeros are immaterial; a percentage and its decimal fraction (e.g. 12.84% and 0.1284) are the same value; adding or omitting a "%" sign never changes correctness when the digits already match the value the reference states; a quantity stated in the dataset's native units (e.g. thousands) matches the same amount written in full.
- Judge precision by value, to a sensible number of significant figures. When the question states a precision, require exactly that. When it does not, accept any answer that is a correct rounding of the reference value — reference answers often carry more decimal places than are meaningful (e.g. a dollar figure written as 64792.44714), and a competent analyst rounds sensibly, so do NOT reject an answer merely for having fewer decimals than the reference. Reject an answer only when its value genuinely differs from the reference (a wrong figure, not a coarser rounding of the same value) or when it discards so much precision that it misstates the quantity.
- Match every required item. If the question asks for more than one item (e.g. "which two tasks"), the response is correct only if it identifies exactly the reference's items. Judge the single set the response commits to and ignore hedged alternatives phrased as "(or ...)"; a response naming different items than the reference — however plausible — is incorrect.
- Honor explicit acceptance and rejection clauses in the reference answer. If the reference names specific values as acceptable or as not acceptable, follow it exactly.

EnterpriseOps-Gym-AA

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0)
• Description: EnterpriseOps-Gym-AA is Artificial Analysis' independent implementation of ServiceNow's EnterpriseOps-Gym benchmark, which evaluates AI agents on stateful, multi-step planning and tool use across realistic enterprise workflows. Agents operate live enterprise systems through tools and are graded on the final state of the underlying databases rather than on their exact sequence of actions.
• Paper: https://arxiv.org/abs/2603.13594
• Dataset: https://huggingface.co/datasets/ServiceNow-AI/EnterpriseOps-Gym
• Agent harness: https://github.com/ArtificialAnalysis/Stirrup
• Domains: We evaluate the benchmark's oracle-mode tasks across all eight enterprise domains: Customer Service Management (CSM), Human Resources (HR), IT Service Management (ITSM), Email, Calendar, Teams, and Drive, plus Hybrid tasks that require orchestrating actions across several of these systems in a single workflow.
• Implementation:
  • Each task runs in an isolated, resettable sandbox: the relevant enterprise systems are brought up as standalone gym servers, each exposing its tools over a live Model Context Protocol (MCP) server and backed by a task-specific SQLite database seeded with synthetic data. Every task clones its own database so runs are isolated and reproducible.
  • We run the benchmark in its oracle tool mode only: the agent is given the set of tools required for the task, isolating planning and execution from tool retrieval. The source dataset's distractor-tool modes are not run.
  • All models are run using our open-source agentic harness, Stirrup, in a standard reason-and-act tool-use loop with a 100-turn cap per task. Each task is run with 3 repeats and the headline score is the mean across repeats.
  • Grading is outcome-based. After the agent finishes, the final state of each task's database is snapshotted and checked with the benchmark's SQL verifiers, which test goal completion, state and integrity constraints, permission and process compliance, and the absence of unintended side effects.
  • Two metrics are reported. The headline success rate is strict pass@1: a task counts as a success only when it passes every one of its verifiers. We also report the verifier pass rate, the share of individual verifier checks passed, as a finer-grained secondary metric.
  • Differences from ServiceNow's benchmark: EnterpriseOps-Gym-AA is our independent implementation, run on our own Stirrup harness and agent prompts, so our numbers are not directly comparable to results reported in the paper.

ITBench-AA

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0)

• Description: ITBench-AA is Artificial Analysis' independent implementation of IBM's ITBench benchmark, evaluating AI agents on Site Reliability Engineering (SRE): Kubernetes incident root-cause analysis.

• Paper: https://arxiv.org/abs/2502.05352

• Repository: https://huggingface.co/datasets/ArtificialAnalysis/ITBench-AA

• Agent harness: https://github.com/ArtificialAnalysis/Stirrup

• Dataset:

  • We evaluate 59 Kubernetes incident tasks: 40 from IBM's public ITBench SRE release and 19 private tasks shared with us by the ITBench team. The headline score is averaged across both splits
  • Each task is an offline Kubernetes incident snapshot containing alerts, events, traces, metrics, logs, and application topology, baked into a scenario-specific sandbox and mounted under /home/user

• Implementation:

  • Each task is run with 3 repeats. The primary score is precision at full recall a repeat receives 0.0 if it misses any ground-truth root-cause entity; otherwise it receives precision over the submitted entities.
  • All models are run using our open-source agentic harness, Stirrup with a 100-turn cap per task. The agent loop informs the language model that its turn limit is approaching during the last 20 turns.
  • The agent is given a single run_shell tool to inspect the snapshot, plus a finish tool to submit its final answer. It must write a structured JSON diagnosis to /home/user/agent_output.json containing the minimal set of independent root-cause Kubernetes entities responsible for the incident, with reasoning and evidence for each, while excluding downstream symptoms
  • Grading uses an LLM judge only to normalize submitted contributing_factors onto the ground-truth canonical entities and alias groups.
  • After normalization, ground-truth alias groups are merged into scoring groups, so equivalent entities such as a pod and its corresponding deployment/service count as the same prediction. If any member of an alias group is marked as a root cause, the merged group is scored as a root-cause target; predicting multiple entities in the same alias group only counts once.
  • Precision at full recall is computed as 0.0 if any root-cause scoring group is missed. If no root-cause groups are missed, it is true_positives / (true_positives + false_positives), where unmatched predictions and predictions mapped to non-root-cause groups count as false positives.
  • GPT-5.5 with medium reasoning effort is used as the grader model for comparing the model’s output with the ground truth for each task

• Generation prompt:

  **Task**:
  
  You are an expert SRE (Site Reliability Engineer) and Kubernetes SRE Support Agent investigating a production incident from OFFLINE snapshot data.
  
  ====================================================================
  # INCIDENT SNAPSHOT DATA LOCATION
  ====================================================================
  Your incident data and working directory is located in
  - /home/user
  
  The final output must be written to /home/user/agent_output.json
  
  Available Python packages:
  - `drain3==0.9.11`
  - `numpy==2.4.5`
  - `pandas==3.0.3`
  
  Both `python` and `python3` are available and use the same environment.
  
  Your objective is to generate a **JSON diagnosis** identifying the root causes of the incident — the minimal set of independent Kubernetes entities whose failures directly explain the incident.
  
  Requirements:
  - Provide reasoning and evidence for every listed entity.
  - When the JSON file is ready, call the provided finish tool and submit `/home/user/agent_output.json`.
  
  All entities MUST use the format: `namespace/Kind/name`
  
  Examples:
  - `otel-demo/Deployment/ad` (Deployment named "ad" in namespace "otel-demo")
  - `otel-demo/Service/frontend` (Service named "frontend")
  - `cluster/Node/worker-node-1` (cluster-scoped resource)
  
  DO NOT include UIDs in the entity name.
  
  ====================================================================
  ## Output Format
  ====================================================================
  Output must consist solely of the final diagnosis in the specified JSON format below — do **not** include any additional text, markdown, or comments:
  
  ```json
  {
  "contributing_factors": [
    {
      "name": "namespace/Kind/name",
      "reasoning": "A short, clear, human-readable explanation for why this entity is a root cause. Reference evidence where possible.",
      "evidence": "Concise summary of supporting facts — relevant alerts, events, logs, traces, or metrics. Plain string."
    }
  ]
  }
  ```
  
  ====================================================================
  # RULES FOR INCLUSION
  ====================================================================
  
  **Only include an entity if both of the following are true:**
  
  1. **There is qualifying evidence** — it appears in at least one of: a firing alert, a Kubernetes event, an error/warning log line, a metric anomaly, or trace evidence directly tied to the incident window. A passing mention in an unrelated log is not sufficient.
  
  2. **It passes the irreducibility test** — you cannot fully explain its failure by pointing to another entity already in the list. Ask: *"If I remove this entity, does my explanation of the incident become incomplete?"* If yes, include it. If another entity already accounts for it, leave it out.
  
  **Do not include** downstream effects, symptoms, or intermediates — only the independent upstream causes.
  
  **Example (exhausted ResourceQuota blocking pod scheduling):**
  
  Causal chain: ResourceQuota exhausted → ReplicaSet cannot schedule pods → Deployment degraded
  
  - ✅ `otel-demo/ResourceQuota/otel-demo-mem-quota` — memory limit exhausted; directly blocks pod creation. Include.
  - ❌ `otel-demo/ReplicaSet/ad-7f9d4b` — failed only because the quota above was exhausted. Exclude.
  - ❌ `otel-demo/Deployment/ad` — degraded as a downstream consequence. Exclude.
  
  **Multiple entries are allowed only if they are truly independent** — two separate upstream causes that do not explain each other.
  
  When in doubt, prefer the most specific Kubernetes object that independently introduced the failure.
  
  ====================================================================
  # INVESTIGATION WORKFLOW
  ====================================================================
  
  ### Phase 1 — Context Discovery
  List available files (alerts, logs, events, topology).
  
  ### Phase 2 — Symptom Analysis
  Read all alert files. Compute:
  - Start time, End time, Duration, Frequency
  
  ### Phase 3 — Hypothesis Generation
  - Create initial hypotheses (e.g. "checkout pods OOMKilled", "redis latency spike").
  - Create a validation plan for each hypothesis.
  
  ### Phase 4 — Evidence Collection Loop
  - Use tools (and generated python code) to gather log, event, metrics, trace evidence.
  - Validate or refute each hypothesis using real data.
  - Explain firing alerts as soon as you find supporting evidence.
  
  ### Phase 5 — Causal Chain Construction
  Build a causal chain like
  `[Config Error] → [CrashLoop] → [Service Down] → [Frontend 5xx]`
  
  ### Phase 6 — Conclusion
  Ensure:
  - All alerts are explained in the reasoning/evidence for the root causes, but do not add downstream entities only to account for alerts
  - All included entities pass the irreducibility test
  - JSON is written to `/home/user/agent_output.json`
  - Call the finish tool and submit the file
  

• Grading prompt:

  You are an expert AI evaluator specializing in Root Cause Analysis (RCA) for complex software systems.
  
  You will be provided with:
  
  1. A **Ground Truth (GT)** JSON object containing entity definitions.
  2. A **Generated Response** JSON object containing predicted entities.
  
  Your job is only to normalize generated entities to ground-truth entities.
  
  Ground Truth fields such as `groups`, `aliases`, `filter`, and `kind` may appear either at the top level of `GT` or under `GT.spec`. Treat `GT.spec` as the ground-truth payload when present.
  
  -----
  
  ### Normalization Rules
  
  Before any downstream scoring can occur, you must accurately normalize entities from the `Generated Response` to the `Ground Truth`.
  
  This process must be based on **explicit evidence** from the entity's metadata.
  You must not infer or guess mappings based on an entity's position in a causal chain.
  
  Only normalize entities from `Generated Response.contributing_factors`.
  
  An entity from the `Generated Response` can only be mapped to a `Ground Truth` entity if a **Confident Match** can be established.
  
  **Definition of a Confident Match:**
  A generated entity is a confident match to a ground-truth entity only if its `name` field, or other explicit identifying metadata, clearly corresponds to the `filter` and `kind` of a ground-truth entity.
  
  **Alias Handling:**
  The `GT.aliases` field contains arrays of equivalent entity IDs.
  If a generated entity clearly matches an entity in an alias group, you may normalize it to the matching GT entity ID from that alias group.
  
  **Workload Kind Equivalence:**
  Treat `Deployment` and `Pod` as equivalent for normalization when the namespace and workload name correspond. For example, `otel-demo/Deployment/checkout` is a confident match for a GT `Pod` entity whose filter matches checkout pods in the `otel-demo` namespace.
  
  **Entity Name Format:**
  Generated entities use the format `namespace/Kind/name`.
  
  Examples:
  - `otel-demo/Deployment/flagd`
  - `otel-demo/Service/frontend`
  - `otel-demo/Pod/checkout-8546fdc74d-d68cn`
  
  Confident match examples:
  - A generated entity with `name: "otel-demo/Service/adservice"` is a confident match for the GT entity with `id: "ad-service-1"` and `filter: [".*adservice\\\\b"]`.
  - A generated entity with `name: "otel-demo/Service/adservice"` can match `ad-pod-1` only if the GT alias set makes that link explicit, for example `["ad-pod-1", "ad-service-1"]`.
  - If `GT.aliases` contains `["load-generator-pod-1", "load-generator-service-1"]`, then normalizing a generated `load-generator-service-1` match to that alias group is valid.
  - A generated `chaos-mesh/Schedule/...` entity whose name matches a GT filter is a confident match for the spawned chaos resource of any kind, provided name and namespace correspond.
  - A generated entity with `name: "67cbd7fe98a0776a"` and no other identifying evidence is not a confident match.
  
  If a generated entity does not have a confident match, leave it unmatched and set its normalized GT entity ID to `null`.
  
  Preserve the original order of the generated `contributing_factors`.
  
  -----
  
  ### Output Format
  
  Return only a single JSON object with this shape:
  
  ```json
  {
  "contributing_factor_entities": [
    {
      "submitted_entity_name": "namespace/Kind/name",
      "normalized_gt_entity_id": "ground-truth-entity-id-or-null",
      "reasoning": "brief explanation of why this is a confident match or why it is unmatched"
    }
  ]
  }
  ```
  
  Rules:
  - Include one item for every generated entity in `contributing_factors`.
  - Preserve input order.
  - Use `normalized_gt_entity_id: null` when there is no confident match.
  - Return only valid JSON.
  
  Given the following Ground Truth (GT) and Generated Response, normalize the generated contributing-factor entities to the Ground Truth.
  
  ## Ground Truth (GT):
  ```json
  {ground_truth}
  ```
  
  ## Generated Response:
  ```json
  {generated_response}
  ```
  
  ## Task:
  1. Look only at `Generated Response.contributing_factors`.
  2. For each such entity, determine whether there is a confident match in the Ground Truth.
  3. If there is a confident match, return the matched ground-truth entity ID.
  4. If there is not a confident match, return `normalized_gt_entity_id: null`.
  5. Do not score anything. Return only the normalization result JSON.
  

Code2Video-AA

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0)
• Description: Code2Video-AA is Artificial Analysis' independent implementation of HeyGen's Code2Video Bench, a set of design briefs for short product and brand videos. It tests how well a model designs these videos in code. Each model writes one HyperFrames HTML composition per brief, and a Gemini 4 Argon judge compares the rendered videos of two models.
• Implementation:
  • Task set: We evaluate 114 of the 168 briefs in Code2Video Bench: 39 from HeyGen's public split and 75 private briefs shared with us by HeyGen. We exclude briefs that contain real-person data, ask for assets that HTML cannot draw, are too vague to judge, or have a reference video that is not 16:9.
  • Generation: Each model gets one brief and HeyGen's system prompt: an instruction to write one HyperFrames HTML composition, followed by the HyperFrames composition schema and its lint rules. It has no tools and answers with one HTML composition. We take one generation per model per brief.
  • Rendering: We render each composition to an MP4 video with HyperFrames 0.8.30, with no network access and a 5-minute limit. A composition that loads remote assets loses them or fails to render (GSAP excepted, which we serve locally).
  • Judging: Gemini 4 Argon compares the videos of two models for the same brief on five axes: engagement, prompt intent, composition, temporal consistency and craft. Each axis has its own comparisons, and each comparison is a separate call. The judge gets the brief, HeyGen's definition of each axis and anonymous labels instead of model names. It answers on all five axes, and only the answer for the comparison's own axis counts. It sees each video at 8 frames per second, with Gemini's high media resolution setting. Each counted verdict is a full win for the preferred video. Gemini 4 Argon is also one of the rated models.
  • Render failures: A composition that fails to render loses every comparison against a video that rendered. When neither composition renders, the comparison is a tie.
  • Sampling: Each axis draws its own comparisons, independently of the other axes. We first sample each model's comparisons evenly across briefs and opponents to seed initial ratings, then switch to Elo-informed sampling that prioritizes pairs of models with similar ratings, while keeping each model's briefs balanced.
  • Scoring: We fit a Bradley-Terry model on each axis. The overall Elo is the mean of the five axis Elos. GPT-5.5 (xhigh) is the anchor at 1000. Each axis interval is a 95% confidence interval from that axis's fit, and the overall interval combines the five. They reflect the sampling of comparisons, not variation across briefs or repeated runs.

Science

MLCR-AA (Medical Long Context Reasoning)

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0); a component of the Artificial Analysis Healthcare & Medical Index
• Description: MLCR-AA is Artificial Analysis' evaluation of MLCR (Medical Long Context Reasoning), an open benchmark from Wisedocs that measures how well models reason over long, fragmented medical records the way claims professionals do when they review insurance and healthcare cases: reconstructing chronology, causality, treatment patterns, and claim relevance.
• Code: Wisedocs-AI/medical-long-context-reasoning
• Public dataset: Wisedocs/mlcr-dataset
• Key details:
  • Realistic, synthetic medical cases of roughly 25,000–64,000 tokens
  • Questions span six difficulty tiers, from locating a single fact to expert-level clinical synthesis and compound multi-part reasoning
  • Unless a question sets its own format, the prompt asks models to answer each part in one paragraph and cite evidence from the record
  • Responses are scored by a panel of three LLM judges (Claude Opus 5.5, GPT-6.1 Sol, and Grok 4.7, each at medium reasoning effort) against expert-annotated ground truth and the source medical record. A response is complete when a majority of judges find it answers every part of the question, does not contradict the ground truth's conclusion, and names each documentation gap that is that conclusion or a step toward it. It is accurate when a majority of judges list no claim that contradicts the record, including claims outside the ground truth
  • Artificial Analysis evaluates a private held-out set of the two hardest tiers (expert-tier clinical synthesis and compound, multi-part reasoning): 60 questions, each run with 3 repeats. This private set is separate from the publicly released dataset
  • The primary score is the pass rate: a response passes when a majority of judges each find it both complete and accurate. Accuracy and completeness are shown alongside it; pass@1

CritPt v2

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0)
• Description: CritPt v2 is the benchmark authors' revision of the CritPt dataset: 70 research-level physics challenges, reviewed by the authors and physics expert collaborators to correct underspecified statements, errors, and typos.
• Website: https://critpt.com/
• Implementation:
  • We run all 70 test challenges of CritPt v2 in our open-source agentic harness, Stirrup, in a Linux sandbox with no internet access. The sandbox has Python 3.13 with numpy, scipy, sympy, and matplotlib.
  • The system prompt is the CritPt authors' one-step prompt, in its version for models with code tools. The user prompt gives the problem, the installed packages, the execution limits, and the submission rules.
  • The model has at most 50 turns. Each response uses one turn, whether or not it calls a tool.
  • The model submits by calling a finish tool with three fields: its reason for finishing, its derivation, and its answer in the code template from the problem.
  • The CritPt authors' grading server scores the submissions of each repeat in one batch. A challenge scores zero if the model submits no answer, for example when it runs out of turns without submitting a response, a provider safety filter blocks it, or the model consumes its maximum output with reasoning.
  • We run 5 repeats for each challenge and report the mean accuracy across repeats (pass@1).

HealthBench / HealthBench Professional

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0)
• Description: We report OpenAI's HealthBench and HealthBench Professional together. HealthBench has 5,000 health conversations, each with a rubric written by physicians. HealthBench Professional has 525 conversations with clinicians, split into consult, writing and research use cases.
• Paper: https://arxiv.org/abs/2505.08775 (HealthBench), https://arxiv.org/abs/2604.27470 (HealthBench Professional)
• Repository: https://github.com/openai/simple-evals
• Implementation:
  • We use the HealthBench and HealthBench Professional datasets that OpenAI publishes with simple-evals (commit 652c89d), pinned by checksum: 5,000 and 525 conversations.
  • Each model receives the conversation as user and assistant turns, with no system prompt and no tools, and writes the next assistant reply.
  • A judge model checks the reply against each rubric item separately with simple-evals' grader prompt and returns whether the item is met. The judge is GPT-4.1 at temperature 0.5 for HealthBench and GPT-5.4 (low) for HealthBench Professional, matching the graders in OpenAI's original implementation.
  • A task scores the points of the items it meets over the total positive points. Items with negative points subtract when met. We average over tasks and repeats and clip the mean to 0-100%.
  • Our headline is the length-adjusted score that OpenAI reports. Before averaging, each task's score drops by a fixed amount for every 500 characters of reply above 2,000 and rises by the same amount below: 2.99 percentage points for HealthBench and 1.47 for HealthBench Professional. We also publish the raw score and the mean answer length.
  • We report HealthBench by its seven themes and its five rubric axes, and HealthBench Professional by use case, by type (good faith or red teaming) and by difficulty. Breakdowns use the raw score, as in OpenAI's original implementation.
  • We run 1 repeat per task for HealthBench and 4 for HealthBench Professional. Scores are the mean across all repeats.
  • A task that still fails after retries scores 0 in every score and breakdown, and is left out of the mean answer length.

General

IFBench

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0). IFBench was removed from the Intelligence Index in v4.1, but we continue to run it on new model releases.
• Description: A benchmark that evaluates a model's ability to follow precise instructions in a single turn. It tests a wide range of skills, including counting, formatting, and sentence manipulation.
• Paper: https://arxiv.org/abs/2507.02833
• Dataset: https://huggingface.co/datasets/allenai/IFBench_test
• Implementation:
  • Uses the single-turn IFBench dataset, which contains 294 questions
  • We run 5 repeats for each question with pass@1 scoring
  • We evaluate responses using the official source code from allenai/IFBench
  • We employ the loose evaluation mode to robustly assess instruction-following, which accounts for extraneous text or formatting by checking several variations of the model's output (e.g., with and without the first and last lines, and with asterisks removed)
  • Our score represents the prompt level accuracy (average across all questions and repeats)
  • We do not use the multi-turn version of IFBench, which uses a different dataset

Global-MMLU-Lite

• Status: Standalone evaluation (not part of Artificial Analysis Intelligence Index v5.0); powers the Artificial Analysis Multilingual Index
• Description: A lightweight, multilingual version of MMLU designed to evaluate knowledge and reasoning skills across a diverse range of languages and cultural contexts.
• Dataset: CohereLabs/Global-MMLU-Lite
• Key details:
  • 6,000 questions (400 per supported language)

• Status: Removed from the Artificial Analysis Intelligence Index in v5.0, having been a constituent up to and including v4.3.2.
• Description: Evaluate long context performance through testing reasoning capabilities across multiple long documents (~100k tokens measured using cl100k_base tokenizer).
• Changes from AA-LCR: Adds a system prompt to clarify grading instructions, corrects 16 answer keys, and grades with GPT-5.6 Luna (medium). Scores are not directly comparable with v1.0.
• Dataset: https://huggingface.co/datasets/ArtificialAnalysis/AA-LCR
• Implementation:
  • 100 hard text-based questions spanning 7 categories of documents (Company Reports, Industry Reports, Government Consultations, Academia, Legal, Marketing Materials, and Survey Reports)
  • ~100k tokens (measured using cl100k_base tokenizer) of input per question, requiring models to support a minimum 128K context window to score on this benchmark. ~3M total unique input tokens spanning ~230 documents to run the benchmark (output tokens typically vary by model)
  • Model responses are evaluated using GPT-5.6 Luna (medium) as an equality checker with pass@1 scoring

HLE (Humanity's Last Exam)

• Status: Removed from the Artificial Analysis Intelligence Index in v5.0, having been a constituent up to and including v4.3.2.
• Description: Recent frontier academic benchmark from the Center for AI Safety (led by Dan Hendrycks).
• Paper: https://arxiv.org/abs/2501.14249v2
• Dataset: https://huggingface.co/datasets/cais/hle
• Implementation:
  • 2,158 text-only questions across mathematics, humanities, and the natural sciences (from the May 2025 revision which contains 2,500 total questions; we use the text-only subset for maximum comparability across models)
  • We note that the HLE authors disclose that their dataset curation process involved adversarial selection of questions based on tests with GPT-4o, Gemini 1.5 Pro, Claude 3.5 Sonnet, o1, o1-mini, and o1-preview (latter two for text-only questions only). We therefore discourage direct comparison of these models with models that were not used in the HLE curation process, as the dataset is potentially biased against the models used in the curation process.
  • Evaluated with the equality checker LLM prompt from the original HLE implementation, using GPT-5.6 Luna (medium), with pass@1 scoring (find prompt below)

CritPt

• Status: Replaced by CritPt v2 (Hard Subset) in v5.0, having been a constituent up to and including v4.3.2.
• Description: Research-level physics reasoning benchmark with unpublished, frontier physics problems spanning a wide range of subfields.
• Paper: https://arxiv.org/abs/2509.26574
• Website: https://critpt.com/
• Repository: https://github.com/CritPt-Benchmark/CritPt
• Dataset: https://huggingface.co/datasets/CritPt-Benchmark/CritPt
• Implementation:
  • We implement the 'challenge' level components for all 70 test-set challenges (the example challenge is excluded) in collaboration with the CritPt team
  • We run 5 repeats for each question with pass@1 scoring
  • The models are called with a two-step parsing approach, where the first step requests that the model complete the challenge with reasoning, and the second step formats the response into the expected code format for grading (see example prompt for parsing on the CritPt evaluation page)
  • Token usage and cost estimates reflect both steps (reasoning and answer parsing)
  • Answer formats include numerical values, symbolic expressions in SymPy, and Python functions (evaluated with test cases)
  • The official CritPt grading server is used to assess all challenge responses for correctness. Grading API access is granted case by case to approved labs and researchers. Email critpt@artificialanalysis.ai to request it, and see the Artificial Analysis API documentation for details

GPQA Diamond (Graduate-Level Google-Proof Q&A Benchmark)

• Status: Removed from the Artificial Analysis Intelligence Index in v4.2, having been a constituent up to and including v4.1.1. We still run it on new model releases and report it as a standalone evaluation.
• Description: Scientific knowledge and reasoning benchmark.
• Subset: Diamond subset (198 questions) selected for maximum accuracy and discriminative power
• Paper: https://arxiv.org/abs/2311.12022
• Dataset: https://github.com/openai/simple-evals/blob/main/gpqa_eval.py
• Key Details:
  • 198 questions covering biology, physics, and chemistry - we test the GPQA Diamond subset of the full GPQA dataset (448 questions total), which was defined by the original authors as the highest quality subset, where both experts answer correctly and the majority of non-experts answer incorrectly
  • 4 option multiple choice format
  • Regex-based answer extraction with pass@1 scoring (prompt and regex below)

𝜏³-Banking

• Status: Removed from the Artificial Analysis Intelligence Index in v4.3, having been a constituent up to and including v4.2. We still run it on new model releases and report it as a standalone evaluation.
• Description: Fintech customer-support domain of the 𝜏-Knowledge framework developed by Sierra, evaluating agents that must coordinate retrieval from a large unstructured knowledge base with multi-step tool-mediated account changes.
• Paper: https://arxiv.org/abs/2603.04370
• Blog: sierra.ai/blog/bench-advancing-agent-benchmarking-to-knowledge-and-voice
• Dataset: https://github.com/sierra-research/tau2-bench
• Implementation:
  • Agents handle ~700 interconnected policy documents (≈195K tokens, 21 product categories) and must locate the relevant policy, reason over it, and execute a multi-step sequence of tool calls, including tools referenced only in documentation rather than explicitly listed
  • We evaluate the full 𝜏³-Banking task suite (97 tasks) with 5 repeats per task and report pass@1 averaged across the repeats, running the upstream tau2-bench v1.0.1 dataset and grader
  • Outcomes are scored against actual backend database state (for example, whether a dispute was opened or a provisional credit issued) rather than conversational quality
  • We use GPT-5.4 Mini (medium reasoning) for both the user simulator and the natural-language assertion judge
  • For knowledge retrieval over the banking corpus we enable BM25 lexical search and grep (bm25_grep mode) inside the original 𝜏-Bench harness
  • We apply a constraint on execution to limit steps to a maximum of 200 per task repeat (the 𝜏-Knowledge reference default for text-mode runs). A 'step' here is the 𝜏-Bench harness definition (every message passed within the simulation, including user simulator turns) rather than only the turns taken by the model under evaluation

FrontierCode 1.1

• Status: Superseded by FrontierCode 2.0. The Coding Agent Index also uses FrontierCode 1.1, but from separate runs of each coding agent, not the runs described here.
• Description: FrontierCode is a coding benchmark from Cognition, built with maintainers of open-source repositories. Each task asks an agent to make a change to a real open-source repository, and the benchmark measures whether the change is good enough for a maintainer to merge. The benchmark grades each change with held-out tests and a rubric of blocking and non-blocking criteria.
• Source: https://cognition.com/blog/frontier-code-1.1
• Announcement: https://cognition.com/blog/frontier-code
• Agent harness: https://github.com/ArtificialAnalysis/Stirrup
• Implementation:
  • We evaluate FrontierCode 1.1 Main, the primary 100-task set of the benchmark's 150 tasks, with 3 attempts per task
  • The FrontierCode verifier grades each attempt with the task's tests and rubric, as described in Introducing FrontierCode. An LLM judge assesses the rubric's review criteria. We use GPT-6 Luna (medium) as the judge
  • An attempt that fails any blocking check, or that the trajectory scanner flags, scores 0. Other attempts get a weighted score across the rubric's criteria. We average each task's attempts, then average the task scores with equal weight
  • We apply the following constraints on evaluations for the agent:
    • We cap the agent at 250 turns
    • Each shell command times out after 7,200 seconds
    • Each attempt has a 14,400-second (4-hour) wall-clock limit. We grade the repository as the agent left it

Terminal-Bench 2.1

• Status: Superseded by Terminal-Bench 4.0 in Intelligence Index v4.3, having been a constituent up to and including v4.2. It remains part of the Coding Index.
• Description: A verified refresh of Terminal-Bench, developed by Stanford University researchers, the Laude Institute, and the open source community. Keeps the same 89 curated tasks across software engineering, system administration, data processing, model training, and security, with environment and instruction fixes that make scores reflect agent capability rather than environment gaps.
• Paper: https://arxiv.org/abs/2601.11868
• Leaderboard: tbench.ai/leaderboard/terminal-bench/2.1
• Implementation:
  • We evaluate the full Terminal-Bench 2.1 dataset (89 tasks) using the Terminus 2 agent harness in an E2B sandbox environment, with pass@1 scoring averaged over 3 repeats per task
  • Each task ships with a verification suite that the agent must satisfy by interacting with the terminal; tasks are considered successful only if every test passes
  • We apply the following constraints on evaluations for the agent:
    • Maximum 'episodes' (where the model reviews current state and plans a series of next actions at the terminal) are limited to 250
    • Per-task agent timeout is set to two hours (7,200 seconds), or the task's own specified timeout where that is longer, well above typical task durations
  • In our testing these constraints predominantly limit cases where models are stuck in an unsuccessful loop, and we see no consistent differences in performance due to these constraints

Terminal-Bench Hard

• Note: Superseded by Terminal-Bench 2.1, which we use going forward. Terminal-Bench Hard was a constituent of the Artificial Analysis Intelligence Index prior to v4.1
• Description: An agentic benchmark developed by Stanford University researchers, the Laude Institute, and the open source community, released in 2025. Terminal-Bench evaluates the ability of agents and models to solve a wide variety of tasks (including software engineering, system administration, and game-playing scenarios) using a terminal interface.
• Page: https://www.tbench.ai/
• Dataset registry: https://www.tbench.ai/registry
• Implementation:
  • We implement the 'hard' subset of the terminal-bench-core dataset, with the latest dataset version as of 14 August 2025 (commit 74221fb); we evaluate 44 tasks from this subset (a small number of tasks are excluded due to external dependency issues in the original dataset)
  • We evaluate this 'hard' subset using the Terminus 2 agent harness for consistency between models, and score models based on pass@1 scoring with the overall average over 3 repeats for each task
  • In the Terminal-Bench framework, each task has a specific suite of tests applied, and are considered successful if all tests pass, or unsuccessful otherwise
  • We apply the following constraints on evaluations for the agent:
    • Maximum 'episodes' (where the model reviews current state and plans a series of next actions at the terminal) are limited to 100
    • We set a global per-task timeout of two hours (7,200 seconds); in practice the 100-episode limit is the binding constraint
    • Models are limited to a maximum of 1 million cumulative input tokens per repeat of each task
  • In our testing these constraints predominantly limit cases where models are stuck in an unsuccessful loop, and we see no consistent differences in performance due to these constraints

𝜏²-Bench Telecom

• Note: Superseded by 𝜏³-Banking, which we use going forward. 𝜏²-Bench Telecom was a constituent of the Artificial Analysis Intelligence Index prior to v4.1
• Description: Benchmark developed by Sierra for conversational AI agents in 'dual control' scenarios with language models simulating both agent and user roles to test planning, tool use, and guidance/communication.
• Paper: https://arxiv.org/abs/2506.07982
• Blog: sierra.ai/resources/research/tau-squared-bench
• Dataset: https://github.com/sierra-research/tau2-bench
• Implementation:
  • The 'telecom' domain introduced in 𝜏²-Bench contains 114 tasks (subsampled from a total 2,285 programmatically generated tasks), with varying 'intents' describing if the task is related to service, mobile data, or MMS issues. We evaluate the telecom domain in full with 3 repeats per task, and report the score using pass@1 scoring as the average of the 3 attempts
  • In this benchmark, the outcome 'world state' decides whether the agent succeeded - for example, whether the user's cell phone data is functioning after the agent completes the task
  • The full 𝜏²-Bench suite includes 3 execution modes with varying planning and communication levels in ablation studies; we implement the 'default' dual control mode with fully simulated and separate user and assistant agents
  • We use Qwen3 235B A22B 2507 (Non-reasoning) for the user agent simulator to ensure consistent checkpoint availability and full control over inference settings alongside strong base intelligence
  • We apply a constraint on execution to limit steps to a maximum of 100 per task repeat

• Dataset: https://huggingface.co/datasets/livecodebench/code_generation_lite
• Key details:
  • Pass@1 evaluation criteria
  • We do not apply LiveCodeBench custom system prompts

Prompt Templates, Answer Extraction and Evaluation

Multiple Choice Questions (GPQA, MMLU-Pro)

We prompt multi-choice evals with the following instruction prompt. This prompt was independently developed by Artificial Analysis, and carefully validated with various ablation studies. We assess that this prompt is a clearer, and therefore fairer, approach than traditional completion-style multi-choice evaluation methodologies or other instruction prompts we tested.

GPQA uses four options (A–D). MMLU-Pro uses ten options (A–J); we use the same structure with additional choices.

Answer the following multiple choice question. The last line of your response should be in the following format: 'Answer: A/B/C/D' (e.g. 'Answer: A').

{Question}

A) {A}
B) {B}
C) {C}
D) {D}

Answer the following multiple choice question. The last line of your response should be in the following format: 'Answer: A/B/C/D/E/F/G/H/I/J' (e.g. 'Answer: A').

{Question}

A) {A}
B) {B}
C) {C}
D) {D}
E) {E}
F) {F}
G) {G}
H) {H}
I) {I}
J) {J}

We extract multiple choice answers using a multi-stage approach to handle various answer formats. For single-letter responses, we use the letter directly. Otherwise, we first attempt to match our primary pattern that looks for formal "Answer: X" format (accounting for optional markdown formatting):

Primary Pattern:

(?i)[\*\_]{0,2}Answer[\*\_]{0,2}\s*:[\s\*\_]{0,2}\s*([A-Z])(?![a-zA-Z0-9])

If the primary pattern fails, we attempt the following fallback patterns in sequence to catch various answer formats:

• LaTeX boxed notation (e.g., \boxed{A} or \boxed{The answer is A})

  \boxed\{[^}]*([A-Z])[^}]*\}
  

• Natural language (e.g., "answer is B")

  answer is ([a-zA-Z])
  

• With parenthesis (e.g., "answer is (C")

  answer is \\(([a-zA-Z])
  

• Choice format (e.g., "D) some answer text")

  ([A-Z])\)\s*[^A-Z]*
  

• Explicit statement (e.g., "E is the correct answer")

  ([A-Z])\s+is\s+the\s+correct\s+answer
  

• Standalone letter at end of response

  ([A-Z])\s*$
  

• Letter followed by period (e.g., "F.")

  ([A-Z])\s*\.
  

• Letter followed by non-word character

  ([A-Z])\s*[^\w]
  

We always take the last match found to account for self-correction in responses.

Equality Checker LLM

For evaluations with open-ended answers (HLE, HLE-Diamond, AA-LCR), we use an equality checker LLM to determine if a model's response is semantically equivalent to the correct answer. This approach uses a language model to assess whether two answers have the same meaning, even if phrased differently. The equality checker evaluates semantic equivalence rather than requiring exact string matches, which is particularly important for questions where multiple valid phrasings exist.

HLE, HLE-Diamond, and AA-LCR share a single equality checker, GPT-5.6 Luna (medium), selected based on validation against human judgment on HLE and AA-LCR. Specific equality checker prompts for each evaluation are detailed in the sections below.

HLE (Humanity's Last Exam)

We prompt HLE with the following text as a system prompt, with a difference between Exact Answer and Multiple Choice questions - these prompts are used with no changes from the original implementation by Hendrycks et al. For models that do not support a system prompt, we prepend the system prompt to the user prompt.

System Prompt for Exact Answer Questions:

"Your response should be in the following format:
Explanation: {your explanation for your final answer}
Exact Answer: {your succinct, final answer}
Confidence: {your confidence score between 0% and 100% for your answer}"

System Prompt for Multiple Choice Questions:

"Your response should be in the following format:
Explanation: {your explanation for your answer choice}
Answer: {your chosen answer}
Confidence: {your confidence score between 0% and 100% for your answer}"

HLE Equality Checker Prompt

We use the following prompt on GPT-5.6 Luna (medium) to check if the response answer is correct - this prompt is again used with no changes from the original implementation by Hendrycks et al.

Judge whether the following [response] to [question] is correct or not based on the precise and unambiguous [correct_answer] below.

[question]: {question}

[response]: {response}

Your judgement must be in the format and criteria specified below:

extracted_final_answer: The final exact answer extracted from the [response]. Put the extracted answer as 'None' if there is no exact, final answer to extract from the response.

[correct_answer]: {correct_answer}

reasoning: Explain why the extracted_final_answer is correct or incorrect based on [correct_answer], focusing only on if there are meaningful differences between [correct_answer] and the extracted_final_answer. Do not comment on any background to the problem, do not attempt to solve the problem, do not argue for any answer different than [correct_answer], focus only on whether the answers match.

correct: Answer 'yes' if extracted_final_answer matches the [correct_answer] given above, or is within a small margin of error for numerical problems. Answer 'no' otherwise, i.e. if there if there is any inconsistency, ambiguity, non-equivalency, or if the extracted answer is incorrect.


confidence: The extracted confidence score between 0|\%| and 100|\%| from [response]. Put 100 if there is no confidence score available.

LCR Equality Checker Prompt

Assess whether the following CANDIDATE ANSWER is CORRECT or INCORRECT.
For the CANDIDATE ANSWER to be correct, it must be consistent with the OFFICIAL ANSWER.

The question, for reference only: {question}
The OFFICIAL ANSWER: {official_answer}
CANDIDATE ANSWER TO ASSESS: {candidate_answer}

Reply only with CORRECT or INCORRECT.

Mathematical Questions (AIME 2025)

We prompt AIME with the following instruction prompt:

Solve the following math problem step by step. Put your answer inside \\boxed{{}}.

{Question}

Remember to put your answer inside \\boxed{{}}.

Mathematical Equality Checker Prompt

As described above, we supplement our script-based grading with a language model equality checker. We use the following prompt with Llama 3.3 70B to check if two answers are equivalent. This prompt was developed by OpenAI and released in their simple-evals repository.

Look at the following two expressions (answers to a math problem) and judge whether they are equivalent. Only perform trivial simplifications

Examples:

  Expression 1: $2x+3$
  Expression 2: $3+2x$

Yes

  Expression 1: 3/2
  Expression 2: 1.5

Yes

  Expression 1: $x^2+2x+1$
  Expression 2: $y^2+2y+1$

No

  Expression 1: $x^2+2x+1$
  Expression 2: $(x+1)^2$

Yes

  Expression 1: 3245/5
  Expression 2: 649

No
(these are actually equal, don't mark them equivalent if you need to do nontrivial simplifications)

  Expression 1: 2/(-3)
  Expression 2: -2/3

Yes
(trivial simplifications are allowed)

  Expression 1: 72 degrees
  Expression 2: 72

Yes
(give benefit of the doubt to units)

  Expression 1: 64
  Expression 2: 64 square feet

Yes
(give benefit of the doubt to units)
