When using openai assistants v2, which models are supported?

I have some old code running with openai assistants beta v1 using model gpt-4-1106-preview and I'm trying to follow steps in:

https://platform.openai.com/docs/assistants/migration

To upgrade to v2. It all works if I keep the model the same but when I try and use any gpt-4o model I get unsupported_model error. Is this just something you can't use with assistants?

Solution

  • The OpenAI Assistants API v2 supports the following models, as of today:

    • GPT-4o (except chatgpt-4o-latest),
    • GPT-4o-mini,
    • GPT-4, and
    • GPT-3.5 Turbo.

    The retrieval tool requires:

    • gpt-4-turbo-preview (and subsequent dated model releases), or
    • gpt-3.5-turbo-1106 (and subsequent dated model releases).

    See the official OpenAI documentation on model endpoint compatibility.
