We read the JSON Schema spec so you don't have to
Summary
Structured generation for LLM outputs is prone to silent constraint violations with JSON Schema. The article presents a compiler-inspired approach (dotjson) that translates schemas through multiple passes to a context-free-like grammar, with its own regex engine to enforce constraints and avoid silent failures. It compares dotjson with XGrammar, discusses feature coverage, and provides access to try dotjson.
