Ah, I missed this part. ChatGPT response after you tell it a function call exists, it can decide whether or not to call it.

    {
      "id": "chatcmpl-123",
      ...
      "choices": [{
        "index": 0,
        "message": {
          "role": "assistant",
          "content": null,
          "function_call": {
            "name": "get_current_weather",
            "arguments": "{ \"location\": \"Boston, MA\"}"
          }
        },
        "finish_reason": "function_call"
      }]
    }

Gotcha. This makes it so that instead of English, gpt-4 can basically spit out/decide when to make function calls now, got it. Thanks.

I wonder how scary this will get if people mistakenly trust it with anything more than a GET. Imagine not being able to trust the reliability of some of the parameters of POST / PUT / DELETE on some reports/internal databases, etc.
