**Anthropic’s Claude Fable 5.1 currently leads Humanity’s Last Exam leaderboards at 59–65%** (text-only vs. tool-assisted runs), ahead of Claude Opus 5 and Mythos 5 variants and Meta’s Muse Spark series near 62%. The 2,500-question expert benchmark, designed to resist saturation, has seen frontier scores climb rapidly through 2026 via improved reasoning chains, extended context, and agentic tool use. OpenAI GPT-6 Astra and Google Gemini previews trail slightly on most independent evaluations. Traders are watching for further 2026 releases, potential HLE-Rolling updates, and whether any lab can push past the current 65% ceiling before year-end 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.
