Getting 429 resource exhausted

Hi @_Khaled_Hesham ,

We apologize for the delay and the inconvenience caused. 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?

hi nireeksha,
We have the same problem for 3 days. We were very far from rate limits. We’ve switched to VertexAI’s api key immidiately at the first day and it didn’t throw 429 till now. However response times are now 2-4x slower.
We tried to use google ai studio’s apikey today again. The problem (429) is still exist.
