The model that wins is the one you can afford to run at scale and explain to a customer. This manual works through quantization, routing, caching, and the plain arithmetic that decides whether an AI feature has a margin or just a demo.
Revenue rarely rewards the biggest model. A working account of latency, cost, and the smaller model that wins the P&L.
This edition is free to read onsite. Each chapter has its own URL, so readers can bookmark, share, and return to the exact section they need.
