Sebastian Raschka releases guide to build reasoning models from scratch
vboykis · x · 2026-09-02
Viviana Boykis recommends Sebastian Raschka's new book, 'Build a Reasoning Model (From Scratch)'. Starting from a pretrained LLM, it covers evaluation, inference-time scaling, reinforcement learning, and distillation. The suggested path includes reading up on Transformer architecture, attention mechanisms, the vLLM paper, speculative decoding, and hands-on coding with exercises.
