According to OriolVinyalsML, Google has released an updated and faster Gemini 3 Deep Think mode delivering PhD‑level reasoning on rigorous STEM tasks with gold medal‑level results on Physics and Chemistry Olympiads. As reported by Oriol Vinyals on X, the upgrade targets long‑chain reasoning and symbolic problem solving, signaling improved step‑by‑step derivations for math, physics, and chemistry benchmarks. According to the linked announcement page, the speed boost reduces latency for multi‑turn, tool‑augmented reasoning, improving reliability for enterprise workloads like technical search, RAG over scientific corpora, and automated problem set grading. As noted by the source, the model’s stronger reasoning implies higher accuracy under chain‑of‑thought constraints and better adherence to structured formats, which can lower post‑processing costs in production. For businesses, according to the announcement, immediate opportunities include STEM tutoring agents, lab assistant copilots for reaction planning, and analytics copilots for formula‑driven financial or engineering models, where Gemini 3 Deep Think’s enhanced logical depth can reduce human review time and increase answer quality.
