Sebastian Raschka completes reasoning-from-scratch video series
Building a reasoning model directly from code demystifies how chain-of-thought-style systems actually work, knowledge that transferable to fine-tuning or evaluating production models. Practitioners and ML engineers who learn best by implementation can follow the series as a structured course. It comes from the author of widely used LLM from-scratch material, so the codebase will likely be maintained and referenced going forward.
