Why is my custom GPT model not visible in the API model list?

Below is an explanation of the situation regarding custom GPTs and API access:

Custom GPTs vs. Fine-Tuned Models

• Custom GPTs created via the ChatGPT interface:
  These custom GPTs (sometimes referred to as "Custom GPTs") are built using the interactive ChatGPT creation tools. They allow you to customize behavior and instructions without needing to work via code. Currently, these models do not appear in the list returned by the /v1/models endpoint and are not accessible via the API.

• Fine-Tuned Models:
  If you’re interested in creating a model that you can interact with through the API, you can use OpenAI’s fine-tuning process. Fine-tuned models are built on top of base models (like GPT-3.5 or GPT-4) and, once created, are available via the API. When making API requests, you reference the fine-tuned model by its name (which will be provided when the fine-tuning process completes).

Summary

At this time, if you created a custom GPT using the ChatGPT interface (the “Custom GPT” feature), it is not currently accessible via the API. To work with a model via the API, you’d need to create a fine-tuned model, as these are the ones that appear in the /v1/models listing and can be used for programmatic inquiries.

If you have further questions about fine-tuning or how to set up your API requests, feel free to ask!
