Large models are evolving from "chat assistants" into real "scientists." On February 13, 2026, Google officially announced a major upgrade to the Gemini3Deep Think deep thinking large model. This model no longer limits itself to everyday conversations but sets its sights on high-level fields such as science, research, and engineering that require rigorous logical reasoning.

Research "Reasoning Mode": Tackling Problems Without a Single Solution

The new version of Deep Think is the result of collaboration between Google developers and top scientists, specifically designed to solve pain points in real research:

Dealing with Complex Environments: It has been deeply optimized for complex problems with ambiguous boundaries, no single standard answer, and messy, incomplete data.

Expanding Access: From February 12, Google AI Ultra subscribers can experience it in the application.

Early Access for Developers: Google has for the first time opened up an "early access program" through the Gemini API to selected researchers and companies.

Outstanding Performance: Dominating Olympiads and Professional Benchmarks

In multiple tests widely recognized as "extremely difficult," Gemini3Deep Think delivered impressive results:

Olympiad-Level Performance: It achieved a gold medal level in the 2025 International Mathematical Olympiad (IMO) test, and also received gold medal ratings in the physics and chemistry Olympiad written exams.

Approaching Human Limits: It scored 48.4% in the "Humanity's Last Exam."

Programming Excellence: It achieved an Elo score of 3455 on the Codeforces competitive programming benchmark, demonstrating strong algorithmic and engineering modeling capabilities.

From "Ranking" to "Implementation": A Digital Assistant in the Lab

Google emphasized that the development of Deep Think was not just to break benchmark test records, but to truly enter the laboratory:

Assisting Engineering Modeling: Helping engineers perform high-precision modeling of complex physical systems through code.

Deep Data Analysis: Assisting researchers in interpreting and mining large and scattered scientific data.

As Gemini3Deep Think becomes fully integrated, AI is transitioning from a mere efficiency tool to a "partner" in scientific innovation.
