AI benchmarks
Every model launch quotes a wall of benchmark names. This directory maps 116 of them across 12 categories, from the coding and agent tests builders watch most to reasoning, math, knowledge, instruction following, long context, multimodal, professional domains, human preference, safety and security: what each one measures, who built it, the year, how it is scored, a representative current top score, and a link to its leaderboard. 27 of them have a full write-up of their own. For models ranked by value, see the value leaderboard; for why these scores are easier to trust some years than others, our guide on whether AI benchmarks are reliable.
What are the main AI benchmarks?
The most-watched AI benchmarks in 2026, by what they test, are:
- SWE-bench Verified and DeepSWE: real-world coding agents
- Terminal-Bench and Frontier-Bench: agentic terminal and senior engineering tasks
- OSWorld 2.0 and AutomationBench: computer-use and business-workflow agents
- ARC-AGI-3: interactive reasoning, and the widest human-model gap left
- Humanity’s Last Exam and GPQA Diamond: expert breadth and PhD-level science
- FrontierMath and AIME: research and competition math
- MMLU-Pro: broad academic knowledge
- LMArena: human-preference ranking (Elo)
- MMMU: college-level multimodal understanding
Older sets like MMLU, GSM8K and HumanEval are now saturated, with top models above 95%, so they are quoted mainly out of habit.
Which benchmarks evaluate AI agent reliability?
The benchmarks built to evaluate agent reliability in 2026 are tau-bench (whether a tool-using agent completes multi-turn tasks consistently, measured pass^k across repeated runs), Terminal-Bench (hard end-to-end command-line tasks), OSWorld 2.0 (computer-use agents on long-horizon desktop work), AutomationBench (cross-application business workflows graded on end state), GAIA and AgentBench (multi-step assistant tasks), and WebArena (long-horizon web tasks). For live rankings from real usage rather than a fixed test set, see Agent Arena; for what the scores mean in practice, our guide to AI agent benchmarks in 2026.
How many AI benchmarks are there?
There is no fixed number: hundreds of AI benchmarks exist, and new ones appear every month as older ones saturate. What is countable is the set frontier labs actually report. This directory maps 116 of them across 12 categories, of which28 are already saturated and 10 were released in 2026 alone. The practical figure to hold onto is smaller still: roughly a dozen benchmarks carry most of the signal in any given model launch, and they are listed above.
What is the hardest AI benchmark in 2026?
By the size of the remaining human-model gap, ARC-AGI-3: humans scored 100% at its March 2026 launch against 0.51% for frontier models, and the ARC-Prize-verified top is still only about 30%. Among knowledge benchmarks the hardest is Humanity’s Last Exam at roughly 53%. For long-horizon agent work, OSWorld 2.0 sits near 20% full task completion. Anything where frontier models score above 90% is measuring its own ceiling instead of the model.
AI benchmarks vs MLPerf: which one do you mean?
The phrase covers two different things. Model benchmarks, the subject of this directory, measure what a model can do: accuracy, task completion, reasoning, reliability. Systems benchmarks such as MLPerf measure how fast and how efficiently hardware runs a fixed workload, reported as throughput, latency and energy rather than capability. A model benchmark tells you which model to pick; a systems benchmark tells you what it costs to serve. For the cost side of that question, see cost per task and the value leaderboard.
What is an AI benchmark?
An AI benchmark is a standardized test, made of a fixed dataset, a task specification, and a scoring metric, used to measure and compare how well AI models perform a specific skill such as reasoning, coding, math, or knowledge. Running many models through the same test produces a single comparable number, which is what a model leaderboard ranks. The catch is that a benchmark only stays meaningful while it is hard: once the frontier clears it, or its answers leak into training data, the score stops telling good models from great ones, and the field has to build a harder one.
How long does an AI benchmark stay useful?
Shorter every year. A benchmark is useful only while the frontier has not cleared it, and that window is collapsing: ARC-AGI-1 survived six years from its 2019 release, the 2021 cohort (HumanEval, GSM8K, MMLU) held for roughly three, the 2023 to 2024 cohort for about two, and ARC-AGI-2 went from 54% to an ARC-Prize-verified 92.5% inside a single year. The trend is not perfectly monotonic, and GPQA Diamond outlasting SWE-bench by a year is a real exception rather than noise we have smoothed away. But the direction is unambiguous, it is the mechanism behind the 28 saturated rows in this directory, and it is why a benchmark name in a launch table means nothing without a date attached to it.

Benchmarks by category
The 116 benchmarks split into 12 categories. Coding and agents is the largest, both because it is the most commercially watched skill and because contamination forced builders to keep replacing the older sets. To search or filter all of them at once, use the directory tool below.

Top scores are representative snapshots as of July 27, 2026, not live readings: leaderboards move constantly, and many figures come from each benchmark's own board (the Leaderboard link in each row). Where no clean current top score could be confirmed from a primary source, the cell reads "Not confirmed." Confirm at the source before quoting a number.

How to read a benchmark score
A headline score is only as good as the benchmark behind it. Four failure modes decide whether a number means anything, and the strongest benchmarks are the ones that resist all four. The scorecard below rates the most-quoted benchmarks on each concern, where higher always means a less trustworthy score. For the full argument and the receipts, read are AI benchmarks reliable and our breakdown of benchmark contamination.
| Benchmark | Contamination | Saturation | Gameability | Real-world gap |
|---|---|---|---|---|
| MMLU (knowledge MCQ) | High | High | High | High |
| SWE-bench Verified (real GitHub fixes) | High | High | High | Medium |
| LMArena (human preference) | Medium | Low | High | High |
| GPQA Diamond (PhD-level science) | Medium | High | Medium | Medium |
| ARC-AGI v2 (abstract reasoning) | Low | High | Medium | High |
| ARC-AGI-3 (interactive reasoning) | Low | Low | Medium | High |
| FrontierMath (research math) | Medium | High | Low | Medium |
| Terminal-Bench 2 (terminal tasks) | Low | Medium | Low | Low |
| Frontier-Bench (senior engineering) | Low | Low | Medium | Low |
Which benchmark should you actually watch?
Pick by the decision you are making, not by whichever number a vendor leads with.
- Choosing a coding model: read a completion benchmark and a quality benchmark together. DeepSWE measures whether an agent finishes the task; FrontierCode measures whether you would merge its code, and the same model can ace one while failing the other. Add Terminal-Bench for agentic, run-it-in-a-real-terminal work, and Frontier-Bench for senior-level feature and debugging tasks, where the best models still sit near 34%. Treat CursorBench with more caution: it is Anysphere's private suite, so nobody outside the company can reproduce a number from it.
- Judging raw reasoning: the ARC ladder moved fast in 2026. ARC-AGI-1 is finished at 97.5% and ARC-AGI-2 went from 54% in December 2025 to an ARC-Prize-verified 92.5% by July, so neither separates the frontier any more. ARC-AGI-3 is now the widest gap on this page: humans scored 100% at its March 2026 launch against 0.51% for frontier models, and the verified top is still only 30.2%. Humanity’s Last Exam remains the unsaturated expert-breadth test at about 53%. Movement on those two is real progress, not noise.
- Comparing general capability: a human-preference ranking like LMArena is the closest to "which feels better to use," but it rewards style as much as substance, so pair it with a composite index and a hard reasoning score.
- Ranking agents, not chatbots: the same team now runs Agent Arena, which scores agents from real usage using causal tracing instead of votes, a method built to resist the style-gaming that dogs preference boards. The Artificial Analysis Coding Agent Index attacks the same problem from the other side, scoring a model and its harness together as one stack, which is what you actually deploy. See cost per task for what those scores cost to achieve.
- Ignore the saturated ones: MMLU, GSM8K, MATH and HumanEval are quoted out of habit. When every frontier model scores above 95%, the benchmark is measuring the ceiling, not the model.
For how these benchmarks rank the current crop of agents, see how the 2026 coding-agent benchmarks actually rank, the coding agents that wrap these models, and the value leaderboard for points-per-dollar.
Why this is a snapshot, not a live feed
Benchmark scores are the most volatile, most gamed layer of model marketing. Leaderboards re-rank weekly, labs report only the tests they win, and the same benchmark can be run under different scaffolds that move the number by ten points or more. This directory is therefore a representative map as of July 27, 2026, built to show what each benchmark means and ground it to its own source, not to quote a score you can hold anyone to. The durable value is the left of the table (what it measures, who built it, whether it is still meaningful); the top-score column is a pointer to the live leaderboard, where you should always confirm before quoting a number.
Frequently asked questions
- What is an AI benchmark?
- An AI benchmark is a standardized test made of a fixed dataset, a task specification, and a scoring metric, used to measure and compare how well AI models perform a specific skill such as reasoning, coding, math, or knowledge. Running many models through the same test produces a single comparable score, which is what model leaderboards rank.
- What are the main AI benchmarks in 2026?
- For coding, SWE-bench Verified, DeepSWE, and Terminal-Bench. For reasoning, GPQA Diamond, ARC-AGI-2, and Humanity’s Last Exam. For math, FrontierMath and AIME. For broad knowledge, MMLU-Pro. For multimodal, MMMU. And for overall human preference, the LMArena Elo ranking. Many older benchmarks like MMLU, GSM8K, and HumanEval are now saturated and quoted mainly out of habit.
- Are AI benchmarks reliable?
- Partly. A benchmark is reliable only as far as its score reflects real capability, and four things erode that: contamination (test data leaking into training), saturation (top models bunched near the ceiling), gameability (a score inflated without real skill), and vendor cherry-picking (a lab reporting only the benchmarks it wins). The most trustworthy benchmarks are contamination-resistant, unsaturated, and run by an independent party. For the full breakdown, see our guide on whether AI benchmarks are reliable.
- What does it mean when a benchmark is saturated?
- A benchmark is saturated when the strongest models all score near its ceiling, so the differences between them are within noise and the benchmark no longer separates a better model from a worse one. MMLU, GSM8K, MATH, and HumanEval are all saturated in 2026, with top models above 95%, which is why the field keeps building harder replacements like MMLU-Pro and ARC-AGI-2.
- What is the difference between SWE-bench and SWE-bench Verified?
- SWE-bench is the original 2,294-task set of real GitHub issues. SWE-bench Verified is a 500-task subset that OpenAI and the SWE-bench authors hand-checked in 2024 to remove broken tests and unsolvable issues, so it is the cleaner, more-quoted version. By 2026 even Verified is treated as saturated and contamination-prone, and OpenAI now recommends the harder SWE-bench Pro instead.
- Which benchmarks evaluate AI agent reliability in 2026?
- The main agent-reliability benchmarks in 2026 are tau-bench, which measures whether a tool-using agent completes multi-turn tasks consistently across repeated runs; Terminal-Bench for hard end-to-end command-line tasks; OSWorld 2.0 for computer-use agents on long-horizon desktop work; AutomationBench for cross-application business workflows graded on end state; GAIA and AgentBench for multi-step assistant tasks; and WebArena for long-horizon web tasks. Agent Arena complements these by ranking agents from real usage instead of a fixed test set.
- What are the new AI benchmarks in 2026?
- The benchmarks that appeared or replaced predecessors in 2026 are Frontier-Bench, 74 senior-level engineering tasks from the Terminal-Bench team; CursorBench, Anysphere private suite mined from real Cursor sessions; OSWorld 2.0, 108 long-horizon computer-use tasks that replace the now-solved OSWorld; AutomationBench, 600 or more cross-app business workflows from Zapier; DeepSearchQA, 900 exhaustive-answer research prompts from Google DeepMind; ARC-AGI-3, the first fully interactive ARC where frontier models scored 0.51% at launch; and the Artificial Analysis Coding Agent Index, which scores whole agent stacks rather than bare models. They exist because the 2024 generation of benchmarks saturated.
- Which AI benchmark matters most for coding?
- There is no single one, because they measure different things. SWE-bench Verified and DeepSWE measure whether an agent can resolve a real issue; Terminal-Bench measures whether it can operate a real terminal end to end; FrontierCode measures whether the code is clean enough to merge; LiveCodeBench measures contamination-free competitive programming. For shipping production code, read a completion benchmark and a quality benchmark together rather than trusting one number.
- What is benchmark contamination?
- Contamination is when a benchmark’s questions or answers leak into a model’s training data, so the model can recall the answer instead of reasoning it out. It inflates scores without reflecting real capability and is the main reason public, static benchmarks decay over time. The defenses are private or held-out test sets, time-stamped problems released after a model’s cutoff, and freshly generated tasks.
- How many AI benchmarks are there?
- There is no fixed number, because new benchmarks are created continuously as older ones saturate. This directory tracks 116 of the benchmarks frontier labs actually report, across 12 categories, 28 of which are already saturated. In practice roughly a dozen benchmarks carry most of the signal in any given model launch.
- What is the hardest AI benchmark in 2026?
- By the size of the remaining human-model gap it is ARC-AGI-3, where humans scored 100% at the March 2026 launch against 0.51% for frontier models, and the ARC-Prize-verified top is still around 30%. Humanity’s Last Exam is the hardest knowledge benchmark at roughly 53%, and OSWorld 2.0 is the hardest agent benchmark at about 20% full task completion.
- Which AI benchmarks are contamination resistant?
- The ones that do not rely on a fixed public test set. Four designs work: private or held-out splits, as in ARC-AGI-2 and GAIA; time-stamped problems released after a model training cutoff, as in LiveCodeBench and SWE-bench-Live; continuously rotated questions, as in LiveBench; and programmatically generated tasks, as in ZebraLogic and RULER. Formal proof benchmarks such as PutnamBench are also hard to fake, because a proof checker either accepts the proof or it does not.
- What is the difference between AI benchmarks and MLPerf?
- They measure different layers. Model benchmarks such as MMLU, SWE-bench and Terminal-Bench measure what a model can do, scored as accuracy or task completion. Systems benchmarks such as MLPerf measure how fast and how efficiently hardware runs a fixed workload, scored as throughput, latency and energy. A model benchmark helps you pick a model; a systems benchmark tells you what serving it costs.
- How long does an AI benchmark stay useful?
- Between one and three years, and the window is shrinking. The 2021 cohort, including HumanEval, GSM8K and MMLU, stayed useful for roughly three years. Benchmarks released in 2024 have lasted about two. ARC-AGI-2, released in 2025, went from 54% to an ARC-Prize-verified 92.5% within a year. A benchmark score is therefore only meaningful with a date attached.
- What is GPQA Diamond, and why is it hard?
- GPQA Diamond is a 198-question set of graduate and PhD-level biology, physics, and chemistry questions written by domain experts to be Google-proof, meaning a non-expert with web access still cannot answer them quickly. It tests reasoning over retrieval. By 2026 top models exceed the roughly 70% human-expert baseline and sit in the low-to-mid 90s, so it is now largely saturated.
