via “regex-constrained generation”
Structured text generation — guarantees LLM outputs match JSON schemas or grammars.
Unique: Converts regex patterns to DFAs and integrates them into the token generation loop for real-time constraint enforcement, avoiding the need for rejection sampling or post-hoc validation.
vs others: Faster and more reliable than regex validation + retry loops because it prevents invalid tokens from being generated in the first place.
