100-word summary
Google just dropped a major upgrade to Gemini 3's Deep Think mode, a specialized reasoning engine built for tackling hardcore science, research, and engineering problems. The results? Gold-medal-level performance on 2025's International Math, Physics, and Chemistry Olympiads, plus an 84.6% score on the ARC-AGI-2 benchmark and a whopping 3455 Elo on Codeforces. Deep Think can even transform sketches into 3D-printable files and model complex physical systems through code. Google AI Ultra subscribers get access now, while researchers and enterprises can request early API access. This positions Google aggressively against OpenAI's reasoning models in the high-stakes AI race.
