UnverifiedConstrained Decoding computes the set of valid tokens at each token step of autoregressive generation based on a finite state machine or context-free grammar and renormalizes the probabilities, mathematically guaranteeing that the output conforms to the target schema.76% similarUnverified结构化输出通过约束解码（Constrained Decoding）在token采样阶段屏蔽非法输出，使LLM格式输出从概率保证变为确定性保证73% similarUnverifiedThe core method of grammar-constrained decoding is to use a context-free grammar (CFG) to filter out illegal token options during the model's token-by-token output generation, setting the logits of illegal tokens to negative infinity.69% similarUnverified从表征到有限词汇的映射过程本质上是一种有损编码（Lossy Encoding）66% similarUnverifiedFunction Calling使用受约束解码（Constrained Decoding）技术在token生成过程中实时校验语法合法性66% similar
