UnverifiedXGrammar is an efficient engine focused on structured generation that ensures outputs conform to predefined format specifications by imposing grammar constraints on output tokens during the decoding stage.76% similarUnverifiedThe essence of supporting AI coding tools is to provide token files as structured text (such as JSON), enabling LLMs to directly read semantic design variables and generate code that conforms to brand specifications.68% similarUnverifiedXberg 的核心定位是作为 ML/数据管道中的文档提取层，负责将杂乱文档转化为干净、结构化文本64% similarUnverifiedConstrained decoding allows only tokens conforming to grammar rules to be sampled by setting the logits of illegal tokens to negative infinity at each decoding step; FSM is applicable to regular languages, while CFG can handle nested structures such as JSON and XML.63% similarUnverifiedConstrained Decoding guarantees at the sampling level that outputs will conform to a specified JSON Schema or regular expression; typical open-source implementations include Outlines, Guidance, and LM Format Enforcer.62% similar
