Hi @ariev.scalia, I came across your post as I was searching for the solution to this issue too today and came upon a curious case. Here’s another thread on this forum that had the same issue. I was surprised to see that the 429 error is raised even when syntax errors prevent access to the model. This seems to be a very misleading and erroneous response from the OpenAI team and I hope it gets resolved too but in the meanwhile, try making one of the tests from the official API Quick Start guide. I used the same and my API keys were working after all. Hope this helps!
