Token Level And Byte Level Parsing With Dual Engine Architecture

via “token-level and byte-level parsing with dual-engine architecture”

Microsoft's language for efficient LLM control flow.

Unique: Implements a dual-engine architecture (TokenParser and ByteParser) that operates at both token and byte levels, enabling constraints to be enforced at the appropriate abstraction level while maintaining correctness at boundaries. Token healing is implemented through careful coordination between engines.

vs others: More efficient than purely byte-level parsing because token-level constraints are faster, and more correct than purely token-level parsing because byte-level constraints handle edge cases at token boundaries.
