Gemini-3.1-flash-image-preview on Vertex AI — 429 RESOURCE_EXHAUSTED on every request

RESOURCE_EXHAUSTED, is quota increase possible?

Getting this error on gemini-3.1-flash-image-preview via Vertex AI:

{

“error”: {

“code”: 429,

“message”: “Resource exhausted. Please try again later.”,

“status”: “RESOURCE_EXHAUSTED”

}

}

Has anyone else run into this? A few questions:

  1. What are the actual rate limits for this model? I can’t find published quotas anywhere.

  2. Is a quota increase available for this model, and if so, how do you request one?

  3. Is this a per-minute or per-day limit?

Any help appreciated.
