deedydas · x · 2026-07-21
This reply to the original IMO 2026 benchmark post adds the source links for the Lean proof and the model runs.
It reinforces the same result: Claude Fable 5, GPT-5.6 Sol, Kimi K3, and Axiom all solved the contest, with Axiom providing a formalized proof in Lean. The linked screenshots also show the safety warning encountered during the run, which is part of the original benchmark context.
