Antigravity 2.0 launches May 19 — Gemini 3.5 Flash, multi-agent orchestration, built-in Chromium browser, scheduled tasks, public SDK
Antigravity 2.0 shipped on May 19 with Gemini 3.5 Flash as the default model, true multi-agent orchestration, a built-in Chromium browser, dynamic subagent spawning, scheduled background tasks, and a public SDK for hosting custom agents. The release positions Antigravity as a serious competitor to Claude Code and Cursor in the developer-agent space, with a fundamentally different bet on what the unit of work should be.
The standout architectural choice is multi-agent orchestration as a first-class primitive. Claude Code and Cursor treat the developer as the orchestrator of a single agent; Antigravity 2.0 lets developers describe goals and have the runtime decompose them into subagent pipelines. That's a heavier-handed bet, but it pairs with the Bayes-consistent orchestration position paper landing in the same week — the field is converging on the framing.
The public SDK and scheduled background tasks are the more commercially differentiating features. Developers can host custom agents on Antigravity's infrastructure and trigger them on schedule rather than only on user prompt. That's a different product surface than Claude Code's terminal-native model, and it speaks to a different user — operators of agent fleets rather than individual developers driving sessions interactively.
