Python API Cannot Find Custom Fine-Tune Model

I created a fine-tune model using gpt-4o-mini-2024-07-18, in the fine-tuning interface.

Using the Python library, I used the full model name (“ft:gpt-4o-mini-2024-07-18…”) as the model parameter in the OpenAI library client.chat.completions.create() method. I kept getting a 404 error - model not found. I tried the same method using “gpt-4o-mini” and “gpt-4o” and those models worked. Also, the fine-tuned model shows up in the Playground and works there.

I used a new API key and set permissions to “All.” I did try models.list() and don’t see the fine-tuned model listed. The new API key is under the Default organization, no project.

I’ve sent this to OpenAI support but no response from them yet. I don’t understand why I can see this model in Playground but not able to access using my API key. Does anyone have insights about how I can make my model accessible, or should I just wait for OpenAI support?
