We actually made it work for simple plugins like JoPilot using ChatGPT API 3.5.
We basically ask ChatGPT API to detect if the API needs to be called and what’d be the body. Then we call the API and pass the data using an HTTP POST request.
With ChatGPT 4 API it will work much better because currently, but can’t check because we’re still waiting for the approval.
ps: we didn’t use Langchain for this.
