Gemini 3 Deep Think: Advancing science, research and engineering

Advancing Science, Research, and Engineering with Gemini 3 Deep Think

February 12, 2026

In a significant upgrade, Gemini 3 Deep Think, a specialized reasoning mode, has been updated to tackle modern challenges across science, research, and engineering. This advanced mode is now available in the Gemini app for Google AI Ultra subscribers and can be accessed via the Gemini API for select researchers, engineers, and enterprises through an early access program.

A Partnership with Scientists and Researchers

The development of Gemini 3 Deep Think was a collaborative effort between Google and scientists and researchers in various fields. This partnership aimed to address complex research challenges that often lack clear guardrails or a single correct solution and data that is often messy or incomplete. By combining deep scientific knowledge with everyday engineering utility, Deep Think moves beyond abstract theory to drive practical applications.

Early Testers' Success Stories

Several researchers and engineers have already utilized the updated Deep Think mode to achieve impressive results. For instance, Lisa Carbone, a mathematician at Rutgers University, used Deep Think to review a highly technical mathematics paper. Deep Think successfully identified a subtle logical flaw that had previously passed through human peer review unnoticed. Similarly, the Wang Lab at Duke University utilized Deep Think to optimize fabrication methods for complex crystal growth, resulting in the successful design of a recipe for growing thin films larger than 100 μm.

Elevating Reasoning with Mathematical and Algorithmic Rigor

Gemini 3 Deep Think has demonstrated exceptional performance in various academic benchmarks, including:

Setting a new standard (48.4%, without tools) on Humanity's Last Exam, a benchmark designed to test the limits of modern frontier models
Achieving an unprecedented 84.6% on ARC-AGI-2, verified by the ARC Prize Foundation
Attaining a staggering Elo of 3455 on Codeforces, a benchmark consisting of competitive programming challenges
Reaching gold-medal level performance on the International Math Olympiad 2025

Navigating Complex Scientific Domains

Beyond mathematics and competitive coding, Gemini 3 Deep Think now excels across broad scientific domains such as chemistry and physics. The updated Deep Think mode demonstrates gold medal-level results on the written sections of the 2025 International Physics Olympiad and Chemistry Olympiad. It also demonstrates proficiency in advanced theoretical physics, achieving a score of 50.5% on CMT-Benchmark.

Accelerating Real-World Engineering

In addition to its state-of-the-art performance, Deep Think is built to drive practical applications, enabling researchers to interpret complex data, and engineers to model physical systems through code. Most importantly, we are working to bring Deep Think to researchers and practitioners where they need it most — beginning with surfaces such as the Gemini API.

Turning a Sketch into a 3D-Printable Reality

With the updated Deep Think, you can turn a sketch into a 3D-printable reality. Deep Think analyzes the drawing, models the complex shape, and generates a file to create the physical object with 3D printing.

Availability and Early Access Program

Google AI Ultra subscribers will be able to access the updated Deep Think mode starting today in the Gemini app. Scientists, engineers, and enterprises can also now express interest in our early access program to test Deep Think via the Gemini API.

Conclusion

The updated Gemini 3 Deep Think mode represents a significant advancement in the field of artificial intelligence, enabling researchers and engineers to tackle complex challenges across science, research, and engineering. With its exceptional performance in various academic benchmarks and its ability to drive practical applications, Deep Think has the potential to revolutionize the way we approach complex problems. As we continue to develop and refine this technology, we are excited to see the impact it will have on various fields and industries.

Future Implications

The implications of Gemini 3 Deep Think are vast and far-reaching. As this technology continues to evolve, we can expect to see significant advancements in various fields, including:

Improved accuracy and efficiency in scientific research and engineering
Enhanced decision-making capabilities in complex systems
Increased productivity and innovation in various industries
New opportunities for collaboration and knowledge-sharing between researchers and practitioners

As we move forward, it will be exciting to see how Gemini 3 Deep Think is applied in various contexts and how it continues to shape the future of science, research, and engineering.
