We are rolling out Deep Think in the Gemini app for Google AI Ultra subscribers, while providing select mathematicians access to the full version of the Gemini 2.5 Deep Think model that excelled in the International Mathematical Olympiad (IMO).\n\n### Functionality of Deep Think\nDeep Think employs parallel thinking techniques to tackle complex problems, excelling particularly in coding and scientific discovery. Users can easily access this tool by toggling it on in the prompt bar of the Gemini app.\n\n### Significant Improvements\nThis release shows substantial enhancements over the initial announcement at I/O, particularly in key benchmark tests and feedback from early testers. The model has reached Bronze-level performance in the 2025 IMO benchmarks, with faster reasoning and better usability.\n\n### Creative Problem Solving\nBy extending inference time, Deep Think allows Gemini to explore various hypotheses more deeply, arriving at creative solutions. We have also developed novel reinforcement learning techniques that encourage the model to utilize these extended reasoning paths, making it a more intuitive problem-solver over time.\n\n### Applications of Deep Think\n1. Iterative Development and Design: Deep Think has shown impressive performance in building complex projects, enhancing both aesthetics and functionality in web development tasks.\n2. Scientific and Mathematical Discovery: Its reasoning capabilities make it a powerful tool for researchers, aiding in formulating mathematical conjectures or analyzing complex scientific literature.\n3. Algorithm Development and Coding: Deep Think particularly excels in tough coding problems that require careful consideration of problem formulation and time complexity.\n\n### Advancing Responsibly\nWe continue to integrate safety and responsibility into Gemini throughout the training and deployment lifecycle. In testing, Gemini 2.5 Deep Think demonstrated improved content safety and tone-objectivity compared to Gemini 2.5 Pro, but showed a higher tendency to refuse benign requests.\n\n### How to Use Deep Think\nAs a Google AI Ultra subscriber, you can use Deep Think today by toggling it in the prompt bar. Deep Think works automatically with tools such as code execution and Google Search, producing much longer responses. We also plan to release Deep Think to a set of trusted testers via the Gemini API to better understand its usability for developer and enterprise use cases.\n\nBlogger's Review:\nThe launch of Deep Think marks a significant advancement in AI tools for solving complex problems. With its parallel thinking and extended reasoning time, this model provides a fresh perspective for scientific research and coding development, promising to play a crucial role in future research and practical applications.
