Schema-constrained decoding for large language models can ensure output adheres to a specific structure, but it does not guarantee the semantic correctness of that output. Even when a model produces output in the correct format, it may still contain plausible but incorrect values, such as selecting an invalid enum value. To ensure accuracy, it is recommended to validate enums against the live source rather than relying solely on the type definition, and to feed parsing errors back as subsequent messages for correction.
