I am unable to use Antigravity because every agent request fails with HTTP 429 Too Many Requests.

Issue:  
“Agent terminated due to error”

Error:  
HTTP 429 Too Many Requests  
RESOURCE\_EXHAUSTED  
“Resource has been exhausted (e.g. check quota).”

Steps to reproduce:

1. Open Antigravity on Windows.
2. Sign in to the affected Google account.
3. Open any workspace, including a new empty workspace.
4. Start a new conversation.
5. Choose any available model.
6. Send a simple prompt such as: “Reply with OK”.
7. The agent terminates immediately with the error.

Expected result:  
The selected model should process the prompt.

Actual result:  
Every model fails immediately with HTTP 429 RESOURCE\_EXHAUSTED, including in new conversations and workspaces.

Troubleshooting already tried:

- Retried the request
- Started a new conversation
- Switched between all available models
- Signed out and signed in again
- Restarted Antigravity / Windows

Please check whether there is an account quota-entitlement, backend routing, or quota-sync issue affecting my account.

Hi @Srishanth_K ,

Thank you for sharing the information.

Because this 429 error occurs immediately even on a basic test prompt and persists after a full sign-out and restart, this points directly to an account-level quota entitlement or backend synchronization state.

To help isolate this:

**Confirm Client Version:**  
Could you let us know the exact version of Antigravity you are running on Windows? If you are not yet on the latest release (such as Antigravity 2.0 `v2.13.0` / Antigravity IDE `v2.5.5`), updating may help resolve known quota lease sync bugs.

Please let us know what version you are currently on.
