Google’s Gemini Deep Think mode is now live in the Gemini app for Google AI Ultra subscribers, marking a major step forward in Google’s Deep Think reasoning capabilities. Offered via Gemini 2.5 Pro Deep Think, this multi-agent model intelligently explores multiple reasoning paths before settling on the most accurate solution.
Launched initially at Google I/O 2025 and publicly rolled out in late July, Google’s Gemini Deep Think mode introduces a shift from fast, shallow answers to deliberate, context-aware analysis for complex tasks.
With Deep Think activated, Gemini can outperform across challenging benchmarks—including LiveCodeBench, the International Mathematical Olympiad standard, MMMU multimodal reasoning tests, and advanced coding puzzles. Recent scores include 87.6% on LiveCodeBench and Bronze-level performance on IMO benchmarks, demonstrating real gains over earlier Gemini versions.
Users accessing Gemini’s Deep Think reasoning mode in the app receive more thoughtful, nuanced responses. Gemini can handle layered prompts requiring hypothesis testing, code execution, and evidence-based conclusions—all powered by a parallel thinking engine built on reinforcement learning and large‑context architecture (1M token window).
This premium feature is available now to Google AI Ultra subscribers ($249.99/month in the U.S.). Rolling out across web and mobile, subscribers can access the mode via a new button in the prompt bar when using Gemini 2.5 Pro Deep Think. Wider access via API, enterprise tools, and Workspace integration is planned in the coming months for trusted testers.
Google’s Deep Think reasoning engine transforms Gemini from a conversational assistant into a deep analytical partner. For developers, researchers, content creators, and educators, Deep Think automates complex reasoning tasks—from code design to research synthesis—saving substantive time and mental effort.
By pushing multiple hypotheses and iterating solutions internally before responding, Google’s Deep Think reasoning mode enables more precise and innovative output. This means fewer superficial answers and more actionable, research-grade insights—ideal for generating technical explainers, strategic reports, or educational content.Moreover, Deep Think’s integration into Gemini makes advanced reasoning tools accessible within one unified interface—without switching platforms. As the model continues to evolve with safety layers and benchmarking feedback, Google demonstrates ambition to lead in thoughtful AI, not just fast AI.
