--- title: "Large Language Model" type: concept tags: [llm, nlp, deep-learning] aliases: [LLM, 大语言模型, Large Language Model] last_updated: 2025-12-20 --- ## Definition Large Language Model,大语言模型。行业通常以参数规模和训练数据/算力来衡量是否称为"大模型",语言模型常在 ≥1B 参数开始被称为"大模型"。 ## Key Facts - 1B = Billion = 10亿参数 - 常见大模型示例:GPT-2(1.5B)、GPT-3(175B)、GPT-4(参数量未公开) - 参数规模是衡量模型能力的重要指标之一 ## Connections - [[Agent]] ← 构建于 ← [[Large Language Model]] - [[Prompt]] ← 输入给 ← [[Large Language Model]] - [[Model Context Protocol]] ← 连接 ← [[Large Language Model]] - [[RAG]] ← 增强 ← [[Large Language Model]] - [[vLLM]] ← 加速推理 ← [[Large Language Model]] - [[Hallucination]] ← 问题 ← [[Large Language Model]] - [[Data Distillation]] ← 蒸馏对象 ← [[Large Language Model]] ## Sources - [[大模型相关术语和框架总结|llm-mcp-prompt-rag-vllm-token-数据蒸馏]]
