TinyTorch: PyTorch's free curriculum to build an ML framework from scratch in 20 modules

PyTorch · x · 2026-09-22

PyTorch's official blog introduces TinyTorch, a free open-source curriculum where learners build a working ML framework from scratch in pure Python using PyTorch's own API — 20 hands-on modules spanning tensors to transformers, no GPU needed, runs on a 4 GB laptop. Led by Harvard/ETH's Vijay Janapa Reddi, it follows the teaching-version tradition of MINIX and xv6, with grading infrastructure universities can adopt for credit. Site: tinytorch.ai.
