He noted that, based on Google’s experience with AlphaGo, AI model responses improve when they’re given more time to think. Also today, Google announced an enhanced 2.5 Flash, considered its workhorse model designed for speed, efficiency and low cost. 2.5 Flash has been improved across the board in benchmarks for reasoning, multimodality, code and long context — Hassabis noted that it’s “second only” to 2.5 Pro on the LMArena leaderboard. Google is making final adjustments to 2.5 Flash based on developer feedback; it is now available for preview in Google AI Studio, Vertex AI and in the Gemini app. Further, 2.5 Pro and Flash now include thought summaries in the Gemini API and Vertex AI.
