Serving
Guided decoding constrains generation so emitted text follows a grammar, schema, or other formal rule. Common implementations mask tokens that would make the current prefix invalid.
Constraints can produce structurally valid output without relying on retries after generation. Grammar processing and token masking add work to each decode step, especially for complex constraints.
The server compiles a constraint, tracks its state, and filters the next-token choices before sampling. Tokenizer behavior, grammar complexity, and implementation strategy determine overhead.
