About
Gemini 2.5 Pro, released March 25, 2025, was Google's first thinking-native flagship — reasoning built into the model rather than offered as a separate mode — and it debuted at the top of the LMArena leaderboard by a wide margin. It combined a 1M-token context window with 86.4% on GPQA Diamond, at the time the strongest published science-reasoning score of any model.
It was arguably Google's definitive 2025 comeback: after a year of trailing OpenAI and Anthropic in developer mindshare, 2.5 Pro made Gemini a serious default for coding, long-document analysis, and video understanding. It held Google's flagship position for nearly eight months until Gemini 3.0 Pro arrived in November 2025.
