Constrained decoding can only guarantee that the syntactic structure of the output is legal (shape); it cannot guarantee the semantic correctness of the output content.

Unverified约束解码保证格式正确，但不保证内容正确80% similarUnverifiedStructural validity does not equal answer correctness; grammar constraints can only guarantee that the output format is legal, and the model can still select the wrong option.78% similarUnverifiedTraditional constrained decoding cannot guarantee that a currently valid prefix can be completed into a fully valid structure within a fixed output length constraint77% similarUnverifiedConstrained decoding can only guarantee that the output format is legal, not that it is semantically self-consistent; when the schema allows fields to be freely combined while mutually exclusive relationships are written only in natural language prompts, small models may generate parseable but business-nonsensical JSON.76% similarUnverifiedAnthropic's structured output implementation moves constraints that cannot be compiled into grammar rules into the field's `description` text, degrading from hard constraints to soft prompts.74% similar
