We're rolling out Deep Think in the Gemini app for Google AI Ultra subscribers, and we're giving select mathematicians access to the full version of the Gemini 2.5 Deep Think model entered into the IMO competition.



Today, we’re making Deep Think available in the Gemini app to Google AI Ultra subscribers — the latest in a lineup of extremely capable AI tools and features made exclusively available to them.

This new release incorporates feedback from early trusted testers and research breakthroughs. It’s a significant improvement over what was first announced at I/O, as measured in terms of key benchmark improvements and trusted tester feedback. It is a variation of the model that recently achieved the gold-medal standard at this year’s International Mathematical Olympiad (IMO). While that model takes hours to reason about complex math problems, today’s release is faster and more usable day-to-day, while still reaching Bronze-level performance on the 2025 IMO benchmark, based on internal evaluations.

Deep Think could be a powerful tool in creative problem solving:
We gave Deep Think in the Gemini app to mathematicians like Michel van Garrel to test mathematical conjectures.

As we put Deep Think in the hands of Google AI Ultra subscribers, we’re also sharing the official version of the Gemini 2.5 Deep Think model that achieved the gold-medal standard with a small group of mathematicians and academics. We look forward to hearing how it could enhance their research and inquiry, and we’ll use their feedback as we continue to improve this offering.

This release represents a significant step forward in our mission to build more helpful and capable AI, and furthers our commitment to using Gemini to push the frontier of human knowledge.
