o3-mini works, o3-pro and others says "this is not a chat model"

[mludvig]

Most OpenAI models work for me but some fail with either of these two error messages:

o3-mini, o4-mini

Works fine

o3-pro

Something went wrong. Here's the specific error message we encountered: An error occurred while processing the request: 404 This is not a chat model and thus not supported in the v1/chat/completions endpoint. Did you mean to use v1/completions? Troubleshooting URL: https://js.langchain.com/docs/troubleshooting/errors/MODEL_NOT_FOUND/

o3-deep-research, o4-mini-deep-research

Something went wrong. Here's the specific error message we encountered: An error occurred while processing the request: 404 This model is only supported in v1/responses and not in v1/chat/completions. Troubleshooting URL: https://js.langchain.com/docs/troubleshooting/errors/MODEL_NOT_FOUND/

Is there any way to make the o3-pro and o3-deep-research work? Some config somewhere? I'm on LibreChat v0.7.9-rc1.

You need to make sure responses API is toggled.

for deep research, it also requires web search.
