Gemini 3 Deep Think Update

Google DeepMind has released a major upgrade to Gemini 3 Deep Think, a specialized reasoning mode designed to solve complex challenges in science, research, and engineering. This update focuses on providing mathematical and algorithmic rigor to tackle problems that lack clear guardrails or single correct solutions, often involving messy or incomplete data.

State-of-the-Art Reasoning and Algorithmic Performance

Gemini 3 Deep Think reaches new performance heights across several rigorous academic and competitive benchmarks. The updated model achieves the following results:

  • Humanity’s Last Exam: 48.4% accuracy (without tools), setting a new standard for benchmarks designed to test frontier model limits.
  • ARC-AGI-2: 84.6% accuracy, verified by the ARC Prize Foundation.
  • Codeforces: An Elo of 3455 on competitive programming challenges.
  • International Math Olympiad (IMO) 2025: Gold-medal level performance.

Proficiency in Scientific Domains

Beyond mathematics and coding, the updated Deep Think mode excels in broad scientific fields, specifically chemistry and physics. It has demonstrated gold medal-level results on the written sections of the 2025 International Physics Olympiad and the 2025 Chemistry Olympiad. Additionally, the model achieves a score of 50.5% on the CMT-Benchmark, demonstrating proficiency in advanced theoretical physics.

Practical Engineering Applications

Gemini 3 Deep Think is designed to move beyond abstract theory into practical utility. The model enables researchers to interpret complex data and allows engineers to model physical systems through code. A specific application of this capability is the ability to convert a sketch into a 3D-printable file by analyzing the drawing, modeling the complex shape, and generating the necessary file for 3D printing.

Availability and Access

The updated Deep Think mode is available immediately in the Gemini app for Google AI Ultra subscribers. For the first time, Deep Think is also being made available via the Gemini API to select researchers, engineers, and enterprises through an early access program.
