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

Google is rolling out its most advanced version of Gemini yet, called Deep Think. It's available exclusively to AI Ultra subscribers on the Gemini app.

However, in order to try out the new model users will need to hand over $250 a month for a Google AI Ultra subscription.Starting today, subscribers get access to a fixed set of prompts for the new model. They can enable “Deep Think” by toggling it in the prompt bar when selecting Gemini 2.5 Pro from the model dropdown menu in the Gemini app.
