Today, we’re rolling out Gemini 3 Deep Think mode to Google AI Ultra subscribers in the Gemini app. This new mode delivers a meaningful improvement in reasoning capabilities, designed to tackle complex math, science and logic problems that challenge even the most advanced state-of-the-art models.
Gemini 3 Deep Think is industry leading on rigorous benchmarks like Humanity’s Last Exam (41.0% without the use of tools) and ARC-AGI-2 (an unprecedented 45.1% with code execution). This is because it uses advanced parallel reasoning to explore multiple hypotheses simultaneously — building on Gemini 2.5 Deep Think variants that recently achieved a gold-medal standard at the International Mathematical Olympiad and at the International Collegiate Programming Contest World Finals.
Ultra subscribers can try Gemini 3 Deep Think mode today by selecting “Deep Think” in the prompt bar and Gemini 3 Pro in the model dropdown.
