I keep reading that you can upload data to one of the GPT interfaces, I'm not sure if it's a ChatGPT plugin, or one of the OpenAI API, but I wonder if you can include some source code that you can then prompt based on... I've been kind of tricking GPT, admittedly I'm currently limited to gpt-3.5-turbo, because with the API you can submit whole conversations and ask for the next reply from the assistant. I don't know how much of that whole conversation it re-reads, but I'll do things like: - Give it a system prompt with guidelines. - Give it my user prompt, which contains a description of what I want it to do. - Give it an "assistant response" which I've faked which is like: "Can you tell me more about the database schema?" - Give it my answer, which is the database schema. - Give it another faked assistant response where it is asking me about the API endpoints I need. - Give it my endpoints... At this point, I then ask it to generate a response. I've found that if I try to combine all the above information into a single prompt, I often run into token limits.
