Superpower your GPT with a custom API (FastAPI, Vercel, ChatGPT)

actions are a very powerful tool for GPT builders, and let you connect to your own APIs. I show you an easy way to build your own API using FastAPI, deploy it to vercel and hook it up to a GPT.

Is FastAPI totally different from the API to programmatically interact with ChatGPT, Au Mistral, Gemini Pro, llama2, etc?

I'd like to prototype an OCR application using Custom GPT.. but is it possible to use Vision/Ai PDF plugin with the free account.. or would I need a ChatGPT4 subscription?


BTW, I imagine there's a limit but I've seen some people use Google Colab to run models for free?! I understand, I could use ChatGPT4 Assistant API and then I, as the developer, would incur the API call cost whenever the app is used. Alternatively, I could host a model like Ollama, on my own computer or on the cloud (beam cloud/ Replicate/Streamlit/replit)?

Unfortunatly it's not working for me :(. ChatGPT just tells me there is no response. The Vercel Runtime Logs show me nothing, if ChatGPT sends a request. So seems like theres nothing send. In Postman or Browser it's working. Nevertheless the video is great. Short and on Point.
