Relevant environment info

- Model: gpt-4o via LiteLLM
- config.json:
  
  {
      "provider": "openai",
      "apiBase": "http://localhost:4000",

    }

Description

gpt-4o (and possibly other models) cannot be used for Autocomplete behind a proxy such as LiteLLM. The requests fail because too many (>4) stop words are supplied.

To reproduce

Proxy gpt-4o using LiteLLM. Try to use this model for autocompletion using provider openai.
