Educational book on building reasoning models from the ground up

An educational book detailing the construction of reasoning models has been released following extensive development over 1.5 years. The work builds upon a previous title covering large language model development and provides practical instructions for implementing modern reasoning techniques. The publication centers on the Qwen3 model as its primary example, with comprehensive coverage of the model's architecture included in appendix sections. Pre-orders are now available through major online retailers such as Amazon, with expected delivery within weeks. The author describes the book as essential reading for those seeking to understand how reasoning models function, given their role as fundamental components in contemporary artificial intelligence agent systems.
