Alongside today’s announcement of Gemini 3 Pro, Google has revealed Antigravity, a development tool that uses Gemini 3 Pro, along with other third-party models. Google says that Antigravity, which supports multiple agents and gives them direct access to the editor, terminal, and browser, is designed for an “agent-first future.”

One of the key components of Antigravity is how it reports on its own work. As it completes tasks, it will produce what Google calls Artifacts: task lists, plans, screenshots, and browser recordings that are intended to verify both the work it’s done and what it will do. Antigravity will also report on its actions and external tool use along the way, but Google says that Artifacts are “easier for users to verify” than full lists of a models’ actions and tool calls.
