I fine-tuned a model with gpt-4o, and it worked great for a week, but then suddenly I became unsupported. My model is still visible in the dashboard and I can use it with the chat API, but my model is no longer visible in the list of models available for assistants.
I get this error when trying to call the Assistant API using my model.
HTTP 400 Bad Request.
! OpenAI API returned an error of type "invalid_request_error" (error code: unsupported_model)
! Caused by parameter model
ℹ The requested model 'ft:gpt-4o-2024-08-06:*********' cannot be used with the Assistants API.
Definately a bug! This is the response I got from OpenAI:
Hi there, Thank you for bringing this to our attention. It appears you’ve encountered an error indicating that the fine-tuned model cannot be used with the Assistants API. This error is due to the current limitation that fine-tuned models are not supported by the Assistants API. As of the latest documentation and updates, fine-tuned models are primarily designed for use with the Completions API. The Assistants API, which facilitates the building of AI assistants within applications, currently does not support fine-tuned models. This is why you’re seeing the unsupported_model error when attempting to use a fine-tuned model with the Assistants API. We understand how this limitation might impact your project, and we’re continuously working to enhance our APIs’ capabilities. Your feedback is invaluable for this process. While we cannot provide an immediate solution to enable fine-tuned models within the Assistants API, we encourage you to explore alternative approaches that utilize the Completions API for leveraging your fine-tuned models. For the latest updates and potential changes to this functionality, please keep an eye on our API documentation and changelog. These resources will provide information on new features, improvements, and any adjustments to the API’s capabilities. If there’s anything specific you’d like to achieve with your fine-tuned model that you’re unable to accomplish through the Completions API, please let us know. We’re here to help you explore alternative solutions or workarounds that fit within the current API capabilities. Thank you for your understanding and for using OpenAI’s services. Best,
Wow, I just had the same experience. I was enjoying my assistant’s abilities while using the FT model but then it went away. Pls bring it back if it isn’t actually a bug. Thanks
This worked perfectly fine days ago and the documentation said that fine tuned models were supported by assistants. What changed? No fine tuned models are showing up in the Assistants model selection - this all worked days ago.
Thank you for raising this issue! We identified a bug on our end and this should be fixed moving forward. Let us know if you encounter any other issues, please!
