Google Antigravity introduces agent-first architecture for asynchronous, verifiable coding workflows

Googlefocused launched yet another coding agent platform, this time focusing on developer teams collaborating to create agents that can execute complex tasks automatically.The platform, called Antigravity, is powered by Gemini 3 and is now available in public preview with “generous rate limits on Gemini 3 Pro usage.” Antigravity is an agentic coding platform that aims to “evolve the IDE towards an agent-first future with browser control capabilities, asynchronous interaction patterns, and an agent-first product form factor.” For the public preview, Antigravity users can build agents using Gemini 3, as well as other leading models such as Anthropic’s Sonnet 4.5 models and OpenAI, open-source GPT-oss. It will be compatible with developer environments running on major operating systems like macOS, Linux, and Windows. “We want Antigravity to be the home base for software development in the era of agents,” Google said in a blog post. “Our vision is to ultimately enable anyone with an idea to experience liftoff and build that idea into reality.”
