Google Rolls Out Gemini 3, Its New Flagship AI, Across Apps, Search and Developer Tools

A higher‑reasoning Deep Think mode enters safety testing ahead of a planned subscriber rollout.

Overview

  • Gemini 3 Pro is live in the Gemini app for all users today, with usage limits tied to plan tiers, and is debuting in Search’s AI Mode for AI Pro and Ultra subscribers in the US.
  • Google is extending access for developers and enterprises via the Gemini API, AI Studio, Vertex AI and the new agent‑first Antigravity platform, which supports autonomous multi‑step coding tasks.
  • The release adds generative interfaces that produce magazine‑style layouts and Dynamic View custom UIs, with AI Mode responses now able to generate interactive tools such as calculators and simulations.
  • Google cites top benchmark results, including an LMArena score of 1501, leading performance on Humanity’s Last Exam and GPQA Diamond, and strong multimodal and coding scores like MMMU‑Pro, Video‑MMMU and SWE‑bench Verified.
  • Safety claims include reduced sycophancy, greater resistance to prompt injection and improved misuse protections, and the experimental Gemini Agent is beginning to roll out within the app for advanced task automation.
