دانلود کتاب Build a Reasoning Model 2026

Build a Reasoning Model (From Scratch) by acclaimed ML engineer Sebastian Raschka is a hands-on, code-driven guide designed to take intermediate Python developers inside the black box of reasoning-enhanced Large Language Models. Instead of treating LLMs as mysterious entities, readers will start with a compact, pre-trained base model that runs on consumer hardware and progressively build its capacity to solve complex, multi-step problems.

The book covers critical, cutting-edge techniques including implementing reasoning improvements at inference time, utilizing reinforcement learning with verifiable rewards, evaluating performance, and integrating external tools. Ultimately, it provides a comprehensive roadmap for constructing a fully functional reasoning stack from the ground up, echoing the underlying mechanics of top-tier models like Grok $4$ and GPT-$5$¹.
