Anthropic'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.

UnverifiedConstrained decoding can only guarantee that the syntactic structure of the output is legal (shape); it cannot guarantee the semantic correctness of the output content.74% similarUnverifiedExtractive summarization is constrained to sentences from the source text and cannot perform linguistic reorganization and compression the way abstractive summarization can.74% similarUnverifiedGrammar-constrained function calling applies grammar constraints to the vocabulary during the decoding phase, restricting the output space to legal function names and argument structures and eliminating format hallucinations, at the cost of reduced flexibility and limited support for nested or free-text arguments.73% similarUnverifiedModern compilers are limited by the various semantic constraints defined by language specifications and cannot make certain aggressive optimizations; with deep understanding of domain knowledge, one can make optimizations that compilers cannot.70% similarUnverifiedStrongly constrained writing refers to generation of text that, besides semantic coherence, must also satisfy hard format conditions such as character counts, sentence counts, rhythm, and the frequency of specific characters.70% similar
