Node-LLM - Build LLMs from Scratch in TypeScript

Show HN: Building an LLM from Scratch in TypeScript

Node-LLM is a hands-on guide that teaches you how large language models work by building one from scratch in Node.js and TypeScript. No black boxes: you'll implement every layer, from attention mechanisms to the training loop, chapter by chapter. The book covers dataset handling, dataloaders, transformer blocks, GPT architecture, and training. Each chapter includes runnable code in the @node-llm/chapters package on GitHub, and interactive WebGPU demos from @node-llm/playground are embedded throughout. Perfect for developers who want to truly understand LLMs by getting their hands dirty.
