LLMs.txt：AI时代的网站“智能身份证”，让大模型读懂你的网站效率提升3倍

当AI模型因HTML冗余代码浪费50%上下文窗口时，LLMs.txtA lightweight content standard designed for large language models to efficiently understand website content through structured files.正成为网站与AI对话的新语言。这个轻量级标准已被AnthropicAn AI research and safety company known for developing large language models like Claude.、CursorA programming tool that integrates with LLMs.txt to enable real-time code-documentation linking.等企业采用，让AI理解内容效率提升3倍。

一、重新定义网站与AI的对话方式

LLMs.txtA lightweight content standard designed for large language models to efficiently understand website content through structured files.是专为大语言模型设计的内容标准，包含两个核心文件：

/llms.txtA lightweight content standard designed for large language models to efficiently understand website content through structured files.：精简导航视图，类似网站“目录”
/llms-full.txt：完整文档内容，采用Markdown格式

与传统标准形成互补生态，为AI提供结构化、易理解的内容接口。

二、破解AI处理网页的三大痛点

传统网页让AI面临三重挑战：

上下文窗口浪费：HTML冗余内容占比超60%
信息结构混乱：导航栏、广告等非核心内容干扰理解
格式不兼容：HTML标签增加AI解析难度

标准结构示例：

# 项目名称
> 项目简介与背景
## 核心文档
- [快速开始](url)：新手引导
- [API参考](url)：接口参数说明

三、从提案到行业实践的落地路径

该标准由Answer.AIA company whose co-founder Jeremy Howard proposed the LLMs.txt standard.联合创始人Jeremy HowardCo-founder of Answer.AI who proposed the LLMs.txt standard for AI-content interaction.提出，目前已形成商业闭环：

工具层：MintlifyA tool that automatically generates LLMs.txt files for websites to optimize AI content understanding.自动生成文件，llmstxt.firecrawl.devAn online service that generates LLMs.txt files to help websites create AI-friendly content structures.提供在线生成
应用层：CursorA programming tool that integrates with LLMs.txt to enable real-time code-documentation linking.编程工具通过LLMs.txtA lightweight content standard designed for large language models to efficiently understand website content through structured files.实现代码-文档实时关联

四、未来适配建议

三类主体需优先布局：

技术文档站点：提升API被AI引用的精准度
内容平台：优化AI摘要生成质量
企业官网：确保品牌信息被AI准确理解

随着ClaudeA large language model developed by Anthropic that integrates with LLMs.txt for improved content processing.、CursorA programming tool that integrates with LLMs.txt to enable real-time code-documentation linking.等工具的深度集成，LLMs.txtA lightweight content standard designed for large language models to efficiently understand website content through structured files.正从可选配置变为AI时代的“基础设施”。
