四、vLLM Guided Decoding 源码解读 目前,vLLM 的 Guided Decoding 功能支持outlines、xgrammar以及lm-format-enforcer这三种后端。下面,我们将使用Qwen2.5-7B-Instruct模型,并基于outlines后端,详细讲解 Guided Decoding 的整体流程及其代码实现。 4.1 加载 LogitsP
一、引言 Guided Decoding,又叫 Structured Output,是大模型推理领域中非常重要的一个特性,主要用于引导大模型输出符合某种特定格式(如:SQL、Json)的结果,以便更好地将大模型落地到具体的应用场景中。在我…
🚀 The feature, motivation and pitch Currently we support guided decoding of (JSON, Regex, Choice, Grammar, and arbitrary JSON) in OpenAI inference server. It would be great that we expose the same functionality in the offline interface a...

--guided-decoding-backend{outlines,lm-format-enforcer,xgrammar}默认情况下,哪个引擎将用于引导解码(JSON 模式/正则表达式等)。目前支持 https:///outlines-dev/outlines, https:///mlc-ai/xgrammar, 和 https:///noamgat/lm-format-enforcer。可以通过 guided_decoding_backend 参数在每个请求中覆盖。
I want to run json guided decoding on vLLM but the model does not seem to follow the choices or the json. Code: def test_guide(): from vllm import LLM, SamplingParams from vllm.sampling_params import GuidedDecodingParams llm = LLM(model="meta-llama/Llama-3.1-8B-Instruct", enforce_eag...
--guided-decoding-backend{outlines,lm-format-enforcer}哪个引擎将默认用于指导解码(JSON架构/正则表达式等)。当前支持https://github.com/outlines-dev/outlines 和 https://github.com/noamgat/lm-format-enforcer。可通过请求中的guided_decoding_backend参数覆盖。
