Why this change? It is unrelated to logprobs? @domdomegg
There was a problem hiding this comment.
I don't believe the current instructions work, and this is how I got it working.
Happy to split this out to a separate PR, or for challenge that the uvicorn command does work.

Summary
The OpenAI compatible server should match the response structure of the OpenAI API for chat completions. Unfortunately there is a discrepancy with the format of logprobs: we return the logprobs format for the completions API, rather than the chat completions API.
This PR:
_convert_text_completion_logprobs_to_chatwhich is used in the chat completion responses to convert the logprobs to the new API formatIssues fixed
Fixes #1787
