Over the last couple of days I’ve been experimenting with a small side project.
It’s a simple app that uses the free tokens from Groq with the Llama 3 Versatile model to try predicting the end-of-day price of Bitcoin.
A GitHub Actions workflow runs it every day at 6:00 UTC. The app pulls the latest market data from API Alpha Vantage, generates a prediction, and stores the results in a free PostgreSQL (Supabase) database so I can track how it performs over time.
To be honest, it may not be much better than flipping a coin 😅 , but that’s not really the point. The goal was simply to experiment and see how quickly you can build and automate something using free services and a bit of AI.
Mostly just a fun little experiment. link: https://btc-forecast.vercel.app/
