Custom Constraint Definition And Composition

via “constraint composition and chaining”

Structured text generation — guarantees LLM outputs match JSON schemas or grammars.

Unique: Computes the intersection of token masks from multiple constraints at each generation step, enabling simultaneous satisfaction of multiple constraint types without sequential validation.

vs others: Allows complex constraint scenarios that would be difficult to express as a single constraint; more efficient than sequential validation because all constraints are enforced during generation.
