Overview
- Antigravity is available now as a free public preview for Windows, macOS, and Linux with “generous” Gemini 3 Pro rate limits that refresh every five hours.
- Developers can choose models beyond Gemini 3 Pro, including Anthropic’s Claude Sonnet 4.5 and OpenAI’s open-weight GPT-OSS.
- Agents produce Artifacts—task lists, implementation plans, screenshots, and browser recordings—to make their work easier to verify.
- Two surfaces support different workflows: an IDE-style Editor and a Manager view that functions as mission control for multiple autonomous agents.
- Users can leave comments on specific Artifacts for non-disruptive steering, and agents retain code snippets or task steps to learn from prior work.
