About this Book
Software needs reliable data, not conversational essays. Learn how grammar-constrained decoding, context-free grammars (CFGs), and strict JSON schemas guarantee 100% syntactically valid outputs that parse directly into your TypeScript and Python types without runtime exceptions.
Target Audience: Backend engineers building mission-critical pipelines that feed database records.
What You Will Learn & Build
Under the hood: Constrained decoding with finite state machines and token masking
Define strict Zod and Pydantic schemas that compile to JSON Schema standards
Handle schema mutations, edge-case fallbacks, and retry strategies gracefully
Extract structured entities from messy PDFs, emails, and invoices with 99.9% reliability
