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)?

FastAPI is just a quick way to spin up an API that can be consumed by any other system. In this case its being used by the GPTs that live inside ChatGPT. For now you need the paid account to create and access these, that might change at some point though. I don't think running in Google Colab changes the pricing of the pay-per-use APIs. You could try hosting on your own computer, from my experience you won't get as good results as GPT4....at least not yet. Also you need expensive hardware as these top models are very resource intensive.

hey! found this really helpful very good ,to the point and quality❤ where do u work and what is ur LinkedIn? are u okay to share would really love to connect cuz I'm working on APIs currently as a college grad and looking for connections and network

Hi! Thanks for watching. I lead enterprise IT projects, but keep that separate from the channel for now. feel free to email:[e-mail] and good luck at college

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.

Thanks for watching! Does ChatGPT show you the right paths after you load in the schema? its just when you test it shows no response? if you want email me the deployed link from vercel and I will take a look: [e-mail]

@@aiunleashed509 Thank you for Feedback and your help is much appreciatet. I send you an E-Mail ;)

[@jonathan_blackburn]

Me either. Maybe they blocked unverified api domain.

[@aiunleashed509]

@@jonathan_blackburn Yes that was the case, you can only use unauthenticated API (like I showed in the video) when it is shared as "Only Me". When it is public you need to add authentication like an API key.
