Build a large language model from scratch with Node.js and TypeScript
What happened
A tutorial on building a large language model from scratch in Node.js and TypeScript hit the Hacker News front page on October 14. It starts in chapter 2 with how models work, then walks chapter by chapter through datasets, data loaders, attention, Transformer blocks, GPT and the training loop, covering the path from data handling to model construction and training. Each chapter has a runnable entry point in the @node-llm/chapters package, with code hosted on GitHub.
