Antigravity Agent 09-2026
Released antigravity-preview-09-2026, which replaces and deprecates antigravity-preview-05-2026. If you run on a remote sandbox (environment: "remote") and read only output_text or model_output steps, update the agent string and nothing else changes. If you run tools locally (local_environment) or parse function_call steps, the built-in tools changed.
