Anthropic's Claude series currently leads Humanity's Last Exam (HLE) leaderboards, with variants like Fable 5.1, Opus 5, and Mythos 5 posting scores from 59% to 65% as of mid-September 2026 on benchmarks measuring expert-level reasoning across math, sciences, and humanities. Iterative releases emphasizing advanced chain-of-thought, tool integration (web search, code execution), and adaptive reasoning have driven recent gains, outpacing OpenAI's GPT-6 Astra and Google's Gemini models on this 2,500-question evaluation designed to resist saturation. Anthropic's internal use of Claude for model development further accelerates progress, though scores remain well below saturation and face potential limits from safety constraints or evaluation protocol shifts. Key catalysts through year-end include additional Opus or Fable iterations and any verified tool-augmented runs that could push the frontier higher before the December 31 resolution.

For resolution, “accuracy” refers solely to the value labeled “HLE Accuracy” or a clear equivalent metric if the data’s presentation or terminology is restructured, regardless of the model’s Calibration Error or any other displayed metric.
The resolution source will be the official Humanity’s Last Exam leaderboard at https://agi.safe.ai/. If the resolution source becomes unavailable during the listed timeframe, this market will remain open to allow the relevant data to become available again. If the source remains unavailable after the end of the listed timeframe or is otherwise confirmed to be permanently unavailable, official Humanity’s Last Exam results published elsewhere may be used. If no official alternative source is available, this market will resolve to "No".
