Google drops Gemini 3, agentic Antigravity IDE

Google is moving beyond chat toward full autonomous agency, positioning Antigravity as the successor to the traditional IDE. The "Deep Think" mode brings chain-of-thought reasoning to complex math, logic, and coding tasks, while the Antigravity IDE replaces text editing with task delegation and uses "Artifacts" for transparency. Performance hitting 84.6% on ARC-AGI-2 signals a major leap in generalized reasoning, supported by a Mission Control interface that allows managing multiple agents working across a codebase simultaneously.
