Google has introduced a new feature inside the Gemini app that focuses on tasks requiring detailed reasoning and careful breakdown. The company has rolled out Gemini 3 Deep Think, and users subscribed to the Ultra tier can access it immediately. The mode is designed for situations where users need deliberate analysis rather than quick responses.

Deep Think builds on Google’s earlier work with structured reasoning. Instead of producing a fast reply, the mode runs several reasoning paths at the same time. This approach helps when a query involves multiple conditions or when the answer depends on examining different options. For example, long-form math questions, complex logic problems or planning tasks that require ordered steps can benefit from this method. The model processes the options, compares them and moves toward an outcome only after checking the possible routes. Google says this process helps the system avoid shortcuts and maintain consistent reasoning across longer prompts.

Inside the Gemini app, Ultra subscribers can access Deep Think as an optional mode. It sits alongside the regular chat experience and can be turned on only when a task needs deeper analysis.

How to Use Deep Think in the Gemini App

Google introduced Deep Think as part of its larger Gemini 3 rollout. The new version features improvements across multimodal tasks, allowing the model to work with text, images, videos, PDFs and screenshots with stronger consistency. The company has also improved the system's ability to process long contexts, plan and handle instructions, so that it can stay aligned with user goals during extended tasks.
