The LLM Manual: A Business Leader's Guide to Choosing, Using, and Deploying Large Language

By P.Z. Murphy

The one book that explains every major LLM - what each does best, what each costs, and how to deploy them in your business.

The AI landscape is bewildering. A dozen models compete for attention, the marketing claims are contradictory, and the practical question - "which model should I use for what?" - remains surprisingly hard to answer. The LLM Manual is that answer.

Strategy consultant P.Z. Murphy delivers a practical, comparative, opinionated guide covering Claude, GPT-4, Gemini, Llama, Mistral, and the broader ecosystem. Each model is assessed with candid analysis of strengths, weaknesses, and ideal use cases. Side-by-side comparison tables cut through the noise.

Original frameworks you'll use immediately:
- SCORE - the 5-factor model selection framework (Sophistication, Context, Output, Responsiveness, Economics)
- CRAFT - the prompting framework that turns vague instructions into professional-quality output
- Cost Optimization Hierarchy - 5 levers to reduce LLM costs by 60-80%
- AI Data Classification - 4-tier security framework for enterprise governance
- AI Maturity Model - map your organization's journey from experimentation to transformation

Complete business application coverage: Sales, marketing, customer success, finance, legal, operations, product, engineering, and data - with specific use cases, prompting strategies, and implementation guidance for each function.

Plus: API and platform comparison, RAG architecture explained, ROI modeling, regulatory compliance, change management, and quick-reference model cards in the appendix.

Whether you're a CEO setting AI strategy, a functional leader choosing tools, or an implementer building applications - this manual gives you everything you need in one place.

Start small. Start now. Build from there.
