Unverified50% confidenceFactExact time
Hard constraints in the decoding phase physically guarantee that outputs conform to predefined grammar or schemas by masking illegal vocabulary options during token generation (logit masking or structured sampling).

UnverifiedThe 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.77% 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76% similarUnverifiedConstrained decoding tools such as Outlines and Guidance allow models to be forced at inference time to produce text conforming to a specific grammar or schema, but potentially at the cost of some generation quality.72% similarUnverifiedConstrained Decoding ensures valid syntactic paths by setting the probability of illegal tokens to zero before each sampling step, based on the content already generated and the target Schema constraints.70% similar
