SimpleQA Verified
Epoch AI’s run of Claude Fable 5.2, released November 2026, scored 94%. The official leaderboard hasn’t tested it yet.
1,000 human-verified, de-duplicated short-answer factual questions measuring parametric knowledge.
Google fixed one dataset error on March 9th, 2026 and posted paper v2 on March 10th, 2026. Scores stay comparable, so it remains one record.

In the authors’ words
We introduce SimpleQA Verified, a 1,000-prompt benchmark for evaluating Large Language Model (LLM) short-form factuality based on OpenAI's SimpleQA. It addresses critical limitations in OpenAI's benchmark, including noisy and incorrect labels, topical biases, and question redundancy. SimpleQA Verified was created through a rigorous multi-stage filtering process involving de-duplication, topic balancing, and source reconciliation to produce a more reliable and challenging evaluation set, alongside improvements in the autorater prompt. On this new benchmark, Gemini 2.5 Pro achieves a state-of-the-art F1-score of 55.6, outperforming other frontier models, including GPT-5. This work provides the research community with a higher-fidelity tool to track genuine progress in parametric model factuality and to mitigate hallucinations. The benchmark dataset, evaluation code, and leaderboard are available at: https://www.kaggle.com/benchmarks/deepmind/simpleqa-verified.
Gemini 3.1 Pro leads with 77.5%
Best score per model from the benchmark's own leaderboard, read on November 12th, 2026. Where a model ran with several settings or harnesses, we keep its best.
Claude Fable 5.2 leads with 94% across all independent runs
Best score per model across the official leaderboard, Epoch AI’s own runs and any board Epoch AI copied. Each bar and row names its source.
Claude Fable 5.2 leads with 94%, claims included
Best score per model from every source, including labs’ own numbers and claims Epoch AI collected from reports and papers. Labs pick their own settings, so a claim can beat an independent run of the same model.

Epoch AI has run 94 models. Labs report scores for 22 models in their cards. Switch the scores above to rank them together.
3 models have held number one on the official leaderboard since its release in September 2025 5 models have held number one across all independent runs since its release in September 2025 5 models have held number one with claims included since its release in September 2025
Lab claims count from the day the card came out, independent runs from the model’s release. We draw one row each for the benchmark’s own leaderboard, Epoch AI’s runs and what labs claim in their cards.

Epoch AI’s run of Claude Fable 5.2 passed 85% in November 2026
All the scores we have, one dot each, so a model tested at several settings appears more than once.

The lab's number comes out ahead in 7 of 8 pairs that differ
Each score a lab reported for its own model, beside the same model's best score on the leaderboard. Gaps mostly come from different harnesses, effort levels and task subsets. 2 of them match, which usually means one side copied the other. Every benchmark.
