New Open AI Models Won't Load

[OfmanAI]

As I begin to migrate over to OpenAI's reasoning models, I can see them in the list but repeatedly get
"Something went wrong. Here's the specific error message we encountered: Failed to send message. HTTP 404 - { "error": { "message": "This is a chat model and not supported in the v1/completions endpoint. Did you mean to use v1/chat/completions?", "type": "invalid_request_error", "param": "model", "code": null } }"

The previous GPT4 versions all work flalwlessly, but the new models simply won't work.
