Implement a ChatGPT-like LLM in PyTorch from scratch, step by step
What it does
This project is a step-by-step guide and codebase for building your own AI chatbot engine — similar to what powers ChatGPT — entirely from the ground up, accompanied by a published book. It demystifies how these AI systems actually work by walking through every stage of construction, from the basic building blocks to training the model on text data.
Why it matters for PMs
With over 85,000 stars, this is one of the most popular AI learning resources on GitHub, signaling massive market appetite for teams who want to understand — not just use — AI technology they're building products on top of. For founders and PMs, this represents a growing movement of companies seeking to reduce dependence on black-box AI providers like OpenAI by developing in-house expertise in how these models actually work.
