Users subscribed to Google AI Ultra can access Deep Think directly in the Gemini app. This new model is not just another iteration of Gemini 2.5; it’s based on the same variant that achieved top-tier scores at the International Mathematical Olympiad (IMO), a global competition where the best student minds go head-to-head on high-level maths problems.
While that IMO version took hours to think through complex problems, the one in the Gemini app is tuned for speed and everyday usability — though still capable of serious reasoning, according to Google’s internal testing.
