Sebastian Raschka is developing a video course on building reasoning models, a topic he has extensively covered on Ahead of AI. Reasoning models, which include most current-generation LLMs, remain highly relevant. The course will begin with a pre-trained base model rather than training one from scratch, to then add reasoning methods. An evaluation step will assess the utility of these additional methods for the model.
