Gemini IMO Deep Think (competition evaluation)

Google

This benchmark entry preserves MathArena's Gemini IMO Deep Think evaluation of the slower competition variant in 2025. Google distinguishes the full IMO model from the faster Gemini 2.5 Deep Think consumer variation released on August 1, 2025. MathArena records the transport endpoint gemini-2.5-pro, which does not uniquely identify the competition checkpoint; its July 25 evaluator date is not treated as a public release date.
