I Built an AI from Scratch & It Talks Like Harry Potter

What if you could train your own AI model at home — on a regular gaming PC — and make it speak like Harry Potter? 🪄⚡

In this video, I’ll take you step by step through the exact process I used to:
Prepare and stream a small dataset so training is fast and doable at home
Train a lightweight GPT model from scratch on OpenWebText
Scale it up for better results with more data and context
Fine-tune the model so it talks in the magical style of the Harry Potter books
Finally, sample text that feels straight out of Hogwarts

This isn’t just about typing commands — I’ll explain why each step matters, in simple language anyone can understand. Whether you’re a beginner curious about AI or a developer experimenting with home-trained models, you’ll walk away with a clear roadmap.
