Show HN: Building an LLM from Scratch in TypeScript
A TypeScript guide shows how to build a GPT-style language model from scratch in Node.js.
A Show HN project is a chapter-by-chapter guide to building a large language model in Node.js and TypeScript without using a black-box framework. It covers the dataset and dataloader, attention, a transformer block, a GPT-style model, and the training loop. Runnable code is published in the @node-llm/chapters package, with interactive WebGPU demos from @node-llm/playground described as coming soon.
