According to @demishassabis, Google AI Ultra subscribers can now access Gemini 3 Deep Think mode in the Gemini app, with full details outlined on the Google Blog. According to the Google Blog, Deep Think is designed for multi-step reasoning, extended context planning, and tool-augmented problem solving, targeting use cases like complex coding assistance, multi-document analysis, and research planning. As reported by the Google Blog, early access is available via the Gemini app for Ultra-tier users, positioning Deep Think as a premium capability that could increase subscription ARPU and differentiate Google’s AI stack for enterprise and prosumer segments. According to the Google Blog, Deep Think emphasizes chain-of-thought style planning outputs while maintaining safety controls, which may improve reliability for workflows like RFP drafting, data pipeline debugging, and product requirement synthesis. As reported by @demishassabis, the rollout is immediate for eligible users, creating near-term opportunities for app developers to test longer-context agents, for enterprises to pilot structured reasoning assistants in regulated processes, and for creators to streamline research-to-draft pipelines within the Gemini ecosystem.

According to Sundar Pichai, Google is making a version of Deep Think—an AI system that achieved gold-medal status at the International Mathematical Olympiad (IMO)—available to Ultra subscribers of the Gemini app, while the official version is now being used by professional mathematicians (source: @sundarpichai, Twitter, August 1, 2025). This move allows Gemini Ultra users to leverage cutting-edge AI for complex scientific reasoning and advanced coding challenges, highlighting practical business applications for industries requiring high-level analytical and problem-solving capabilities. The deployment of Deep Think is set to enhance productivity in scientific research, STEM education, and tech innovation, opening new market opportunities for AI-powered problem-solving tools.
