Google AI Ultra subscribers now have access to Deep Think, Google’s most advanced reasoning model yet for Gemini 2.5. The new model was first unveiled at Google I/O, and after feedback from "early trusted testers,

Google says the model outperformed several of its competitors in key AI benchmark tests and a variation of the model even achieved the gold-medal standard at this year’s International Mathematical Olympiad (IMO),

A version of the AI model achieved gold-medal standard at the International Mathematical Olympiad earlier this year.

Google DeepMind, Alphabet Inc.’s artificial intelligence research arm, today announced the rollout of Gemini 2.5 Deep Think, a new creative problem-solving AI model. The company stated the model is capable of addressing complex problems by considering multiple ideas simultaneously and choosing the best answer.
