Google Releases Major Gemini 3 Deep Think Upgrade
Narrative
Major upgrade to Gemini 3 Deep Think specialized reasoning mode, built to tackle modern science, research, and engineering challenges. Developed with scientists/researchers for messy, incomplete data scenarios. Achieves 48.4% on Humanity's Last Exam (without tools), unprecedented 84.6% on ARC-AGI-2, 3455 Elo on Codeforces (Legendary Grandmaster tier), and gold-medal performance on 2025 Physics and Chemistry Olympiads.
Reality
Released February 12, 2026. Available immediately to Google AI Ultra subscribers ($20/mo) in Gemini app. First-time API access for select researchers, engineers, enterprises (early access program). Outperforms previous Deep Think and standard Gemini 3 Pro on rigorous benchmarks through advanced parallel reasoning and test-time compute.
Implication
Positions Google's reasoning capabilities against OpenAI o-series and Anthropic extended thinking modes. Targets academic/enterprise applications requiring deep analytical rigor over speed. Demonstrates shift toward specialized reasoning modes as differentiation strategy. Real-world validation includes identifying logical flaws in peer-reviewed papers and optimizing semiconductor crystal growth.
