Start with the exact message
Searches for antigravity cli rate limit are often panic searches after the CLI refuses another prompt. The first step is to copy the exact error message and separate four different cases: authentication failure, account access failure, model or plan limit, and a temporary quota/rate-limit response.
Because Google can change plan limits and model availability, this page should not invent numeric quotas. The useful job is to help users collect evidence and choose the right next action.
What to collect before changing plans
Before upgrading, downgrading, or switching accounts, collect the exact error text, timestamp, account type, whether the same account works in the desktop Antigravity app, and whether the failure happens on short prompts or only on long autonomous tasks. Also record whether you recently migrated from Gemini CLI, because the account bucket or entitlement path can differ from what you used before.
If the error disappears after waiting, it was likely temporary throttling. If it repeats immediately on every prompt, focus on account access or authentication. If it only appears during large refactors, split the task, reduce parallel agent work, and ask the CLI to create a plan before edits. This makes the page useful without pretending to know private quota numbers.
