Deep Think is Gemini’s “specialized reasoning mode,” and Google today announced a “major upgrade” to let it “solve modern challenges across science, research, and engineering.”
Google worked with scientists and researchers on this update, with the goal of using Deep Think to “tackle tough research challenges” that “often lack clear guardrails or a single correct solution and data is often messy or incomplete.”
By blending deep scientific knowledge with everyday engineering utility, Deep Think moves beyond abstract theory to drive practical applications.
In terms of benchmarks for this Gemini 3 Deep Think upgrade, Google highlights:
- 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
This leap in mathematics and competitive coding is joined by boosted performance in chemistry, physics (including theoretical), and other scientific domains.
Practical applications for Deep Think allow “researchers to interpret complex data, and engineers to model physical systems through code.”
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.
This Gemini 3 Deep Think upgrade is now available in the Gemini app for Google AI Ultra subscribers, while Google is also making it available via the Gemini API (express interest for early access here) for enterprise users.
