Identity (H1)

Site name and essential
summary for the model.

Primary Resources

Direct URLs to Markdown
(.md) files without noise.

Optional Section

Disposable content if the
"context window" is limited.

Author & Origin

Proposed by Jeremy Howard (Fast.ai) in Sept. 2024 to standardize how LLMs consume websites.

The Problem

HTML has too much "noise" (JS, ads, menus) for the limited context window of an AI.

Inference

Designed for real-time use, not just training.

Concise

Unlike sitemap, this is an expert summary.

Predictive

Uses Markdown: the format that models understand best.

Location

It is placed at the site root: /llms.txt
