+## Companion Book / Sequel
+
+[*Build A Reasoning Model (From Scratch)*](https://mng.bz/lZ5B), while a standalone book, can be considered as a sequel to *Build A Large Language Model (From Scratch)*.
+
+It starts with a pretrained model and implements different reasoning approaches, including inference-time scaling, reinforcement learning, and distillation, to improve the model's reasoning capabilities. 
+
+Similar to *Build A Large Language Model (From Scratch)*, [*Build A Reasoning Model (From Scratch)*](https://mng.bz/lZ5B) takes a hands-on approach implementing these methods from scratch.
