Unable to Use Fine-Tuned Model – Access Issue Despite Correct Setup

Hello everyone,

I’m facing an issue with fine-tuning, and I can’t find a solution anywhere. I’ve seen that other users have encountered the same problem before, but I haven’t found a clear resolution in any case.

Some suggest checking if the model was created within the same project you’re trying to use, while others recommend verifying if it is properly enabled. I have confirmed both, but the issue persists.

Issue Description:

I created a fine-tuned model, uploaded a JSONL file, and the entire process was completed successfully via the API. After receiving the confirmation that training was completed, I attempted to use the model by making a request. However, I encountered the following error:

Project `proj_kmr5Wmb6s4BMDz2MDHm9WlMo` does not have access to model `ft:gpt-3.5-t (truncated...)"```

I have double-checked everything—API keys, project settings, and even attempted to generate a response directly through the OpenAI Dashboard—but no matter which model I train, I always receive this error. You can see the attached image for reference.

Has anyone experienced this before and found a solution? Any help would be greatly appreciated! (Apologies if this

 is a basic question, haha.)

Thanks in advance! 🚀
