Constrained Decoding: Architecture for Guaranteed-Valid LLM Output (2026)
How constrained decoding guarantees valid LLM output: grammars, FSAs, token masking, JSON-schema enforcement, and where structured generation breaks in production.
LLM JSON Mode: A Structured-Output Benchmark (2026)
A 2026 benchmark of LLM JSON mode and constrained decoding: throughput, latency, and accuracy across grammar-based methods, with reproducible methodology.
