Persistent HTTP 429 RESOURCE_EXHAUSTED across all models

Google Antigravity
1

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.
