The Craft of Post-Training is a practical guide to turning foundation models into production-ready systems - reshaping behavior, aligning to your values, and deploying with confidence. Each technique is taught concept-first, then implementation-through-code, so you understand not just what to run, but what you're actually changing inside the model. You'll leave with the skills to: Fine-tune models on curated datasets using supervised fine-tuning, LoRA, and QLoRA without destroying the base model's general capabilities; Apply reinforcement learning from human feedback and modern preference optimization methods, including GRPO, ORPO, and beyond, to shape model behavior; Evaluate models rigorously: design benchmarks, detect regression, and measure quality claims that survive scrutiny; Adapt models to specialized domains, from clinical language to legal text, turning general capability into a defensible competitive advantage; Train agentic models that take sequences of actions reliably, not just models that talk about taking actions; Quantize and compress fine-tuned models for deployment without sacrificing the gains you trained for. Post-training is where models stop being impressive and start being useful. This book teaches you to do it right.\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublication date:\u003c\/strong\u003e 1 September 2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePage count:\u003c\/strong\u003e 416\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Height 235 mm; Width 178 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublisher:\u003c\/strong\u003e No Starch Press,US\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Paperback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISBN-13:\u003c\/strong\u003e 9781718505209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Chris Von Csefalvay","offers":[{"title":"Paperback","offer_id":50207191630074,"sku":"9781718505209","price":48.84,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0522\/4297\/2845\/files\/9781718505209.jpg?v=1788220133","url":"https:\/\/shulphink.com\/products\/the-craft-of-post-training-9781718505209","provider":"Shulph Ink","version":"1.0","type":"link"}
