Describe the feature

Some services, like Perplexity AI, offer an OpenAI-compatible drop-in replacement API. By providing a way to change the URL Zed uses to send requests to OpenAI, it would get support for these services "for free".

If applicable, add mockups / screenshots to help present your vision of the feature

Something like:

{
  "assistant":  {
    "default_open_ai_url": "https://api.perplexity.ai/"
    ...
  }
}

I was looking for this setting, it's surprising that it's not implemented already.

Ollama now has openai compatible API ( for chat completion) so it's a great time to get this added

This would be a great enhancement. I'd also like to point out that LM Studio also offers an OpenAI compatible API locally.

It could work similarly to the Continue plugin for VSCode.

Sample of Continue config.json:

{
  "models": [
    {
      "title": "GPT-4",
      "provider": "openai",
      "model": "gpt-4"
    },
    {
      "title": "Mixtral",
      "provider": "lmstudio",
      "apiBase": "http://localhost:1234/v1",
      "completionOptions": {},
      "model": "mixtral-8x7b"
    }
  ]
}
