Antigravity enterprise returning 429

Like many here, I am getting 429s when using Antigravity e.g.
Error: RESOURCE_EXHAUSTED (code 429): Resource exhausted. Please try again later. Please refer to Error code 429  |  Gemini Enterprise Agent Platform  |  Google Cloud Documentation for more details.
This is on an enterprise PayGo plan. I believe that there is an option with the cloud services to use a priority PayGo for cloud services, and this can be enabled by adding headers to the HTTP requests. There doesn;t seem to be any way to do this without using some whacky proxy to insert these - is that really true, and is there a better way to avoid these errors ?

Hi @Bruce_Jackson,

Good news: you don’t need a proxy. Antigravity supports Priority PayGo out of the box.

  1. Update to the latest version.

  2. Open ~/.gemini/config/config.json (on Windows: %USERPROFILE%\.gemini\config\config.json) and add:

    { "userSettings": { "vertexServiceTier": "priority" } }

  3. Restart Antigravity fully.

A few other things that help with 429s:

  • Switch to the Global endpoint in Settings → Account → Manage, if your data residency rules allow it.
  • Check your Cloud project for any Vertex AI quota limits.
  • Use Flash for routine tasks and run fewer agents at once.
