Token Level Constraint Enforcement With Llguidance Integration

via “token-level constraint enforcement with llguidance integration”

A guidance language for controlling large language models.

Unique: Compiles grammar constraints into a state machine that filters token logits during inference, implemented through llguidance C++ extension for performance. This is the core mechanism that enables reliable constraint enforcement without post-processing.

vs others: More reliable than post-processing validation because constraints are enforced during generation, and more efficient than rejection sampling because invalid tokens are filtered rather than sampled and discarded.
