Takeaway

Antigravity reframes the IDE around an agent manager that orchestrates editor and browser agents, leveraging Gemini 3's longer-horizon multimodal tool use.

Summary

  • Launches Google Antigravity, an agent-first IDE from DeepMind with three surfaces: editor, agent-controlled Chrome browser, and an agent manager.
  • Agent Manager acts as a higher-level inbox/control panel for many parallel agents, with OS-level notifications and <100ms switching to the editor.
  • Agent-controlled browser executes JavaScript, scrolls/clicks, and produces recorded verification videos instead of just diffs.
  • Built around Gemini 3 Pro's gains in intelligence/reasoning, longer-running tasks, tool nuance, and multimodal capabilities.
  • Frames product evolution as autocomplete → chat → agents, each unlocked by a model-capability step function.
