Stanford CS336 Spring 2026 Opens Up: Learn to Build LMs From Scratch for Free
stanfordnlp · x · 2026-09-25
Stanford has published the Spring 2026 page for CS336, Language Modeling from Scratch, taught by Percy Liang and Tatsunori Hashimoto, with lecture videos available as a YouTube playlist that anyone can use for self-study.
Course highlights:
- Philosophy mirrors the OS course's "write an OS from scratch": students work through the entire language-model pipeline hands-on, including pretraining data collection and cleaning, building a Transformer, and pre-deployment training and evaluation
- Prerequisites: strong Python (assignments are mostly Python) and heavy reliance on math fundamentals
- Lectures run Monday/Wednesday afternoons; office hours cover the entire teaching staff, and course Q&A happens in a public Slack
- The 2024 and 2025 spring editions are already public; it's a highly regarded hands-on "build a model" course in the AI community, recommended as a one-stop resource for AI builders from beginner to advanced
