These models are not deprecated and will continue to be served until further notice through the API. For any new projects, use our latest models: 3.5 Flash-Lite or 3.8 Flash. This helps us maintain sufficient capacity for both ongoing legacy workflows and new applications.++## September 17, 2026++- 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.
