Sebastian Raschka released a from-scratch video course on building reasoning models

If you liked his LLMs-from-scratch book, this covers reasoning models: inference-time scaling, RL training and so on, all in code. Good weekend project or too heavy without a decent GPU?

most chapters run fine on a single consumer gpu or colab, the RL part is slower but doable
