Trying to use 3.5 turbo

[rdecosta]

I'm trying to use 3.5-turbo, but there's no obvious method for setting this. If I use the url OpenAI suggests (https://api.openai.com/v1/chat/gpt-3.5-turbo/completions) I get Error Message: Cannot specify both model and engine

Hi @rdecosta, the endpoint you describe does not exist in that form. The chat completion endpoint is https://api.openai.com/v1/chat/completions And the names of models that could be used are listed here. https://platform.openai.com/docs/models/model-endpoint-compatibility

Using this plugin you can make a request such as:

var req = new CreateChatCompletionRequest
{
  Model = "gpt-3.5-turbo",
  Messages = new List<ChatMessage>()
  {
    new ChatMessage() { Role = "user", Content = "Hello!" }
  }
};
var res = await openai.CreateChatCompletion(req);

If I change the hard-coded (?) endpoint to the one you suggest, I get Error Message: Invalid URL (POST /v1/chat/completions/completions)

the code snippet above doesn't seem to make allowance for changing the endpoint. Unless I'm missing something really obvious.

The plugin covers all the endpoints, you do not need to change anything in this case.
You can check OpenAiApi.cs and all the possible calls are covered there.
