Google rolls out Deep Think to Gemini AI Ultra users

Google has launched Deep Think for AI Ultra subscribers within the Gemini app, with the Gemini 2.5-based model also available to select mathematicians, offering powerful tools for complex problem-solving and mathematical exploration.

Google’s Deep Think AI, improved from its I/O version, offers quicker reasoning and enhanced usability. It achieved Bronze-level performance on the 2025 IMO standard in internal benchmarks.

Select mathematicians are now using Deep Think to test conjectures. Google notes its excellence in creative problem-solving through parallel reasoning for refined outcomes.

The model has been given extended inference time, enabling deeper analysis and more inventive answers. Reinforcement learning techniques guide it to explore longer reasoning paths, improving its problem-solving ability.

Beyond maths, Google considers Deep Think useful for design, planning, and coding. It can enhance web development, reason through scientific literature, and tackle algorithmic challenges, supporting users with strategic and iterative thinking across disciplines.
