Gemini 3 Deep Think: AI for Engineers

On February 13, 2026, Google DeepMind released a major update to the Deep Think mode based on Gemini 3. The tool now supports specialized agentic workflows (Aletheia) for solving complex problems in physics and engineering.

This is a shift from a "universal talker" to a "narrow specialist." Deep Think can not only code but also construct mathematical proofs and model physical processes, becoming a real partner for R&D departments.
