Gemini API 429 Rate Limit Errors

Gemini API

I’m experiencing persistent 429 (Too Many Requests) errors when calling the Gemini API through the OpenAI SDK compatibility layer, even though:

  1. I’m the only user testing the API (single user, sequential requests)
  2. I’ve sent only ~39 requests total on Dec 10, 2025
  3. My quota usage appears normal and not exhausted
  4. I’m unable to use any Gemini API calls across any of my projects. I have not exhausted limits i am sure.

request you all for your inputs thanks.

I am also having this issue. I’m on tier one but I will randomly get completely blocked with 429 errors even though I’m staying well below limits (have checked both google cloud and google ai studio rate limits to confirm).

It’s on and off. Sometimes it will work, and then it will stop for hours at a time.

Hi @Aditya_kumar_singh @Nick3 , Welcome to forum!!!

Thank you for bringing this to our attention. Could you please provide the project number (not the project ID) via direct message if you are still facing this issue?
