LLM Endpoint
Also known as: llm.json, LLM.txt, AI endpoint
A machine-readable file (llm.json or LLM.txt) published on a website to provide AI language models with structured information about the site's identity and content.
An LLM endpoint is a machine-readable file published on a website's root to provide AI language models with structured information about the site's identity, purpose, content coverage, and related properties. The two primary formats are llm.json (a structured JSON file) and LLM.txt (a plain-text declaration).
LLM endpoints are knowledge assets that serve as direct communication channels between a website and the AI systems that crawl and index it. They supplement traditional schema markup and sitemap files with a declarative layer that is optimized for language model consumption rather than traditional search crawler processing.
