Structured Output Doesn't Validate LLMs. It Resamples Them
TL;DR — Constrained decoding for structured output (JSON mode, grammar-based function calling) doesn't just check a model's answer — it rewrites the model's token-by-token probability distribution in real time. That reshaping can force a model into low-probability paths it never 'wanted' to take, a…
