Welcome to the Forum.
The Model unavailable, retrying message is not caused by your plan’s usage quota—it typically occurs when a model experiences temporary server capacity constraints or when a long conversation with large file changes times out while waiting for a response.
Please try the following steps:
- Update to Antigravity
v2.31.0: Make sure you are on the latest release from the Changelog, which fixes an issue where requests failed and retried when a thinking model took more than a minute to start responding. - Start a new conversation: Continuing a long thread after large multi-file edits (like the 17-minute turn in your screenshot) carries heavy context that can trigger timeouts. Starting a fresh conversation helps clear the stuck state.
- Adjust thinking level or switch models: From the model selector under the prompt box, try lowering the thinking level to
LoworMediumfor faster responses, or switch to another model available on your plan (such as Gemini 4 Argon or Claude Sonnet 5.5 (thinking) on Google AI Pro).
Please let us know if the issue persists after updating and starting a fresh conversation.
