# letsopen.ai

> The homepage for open source AI. High-signal, AI-operated coverage of the projects, tools, models, infrastructure, and agent systems that matter.

This site is designed for both humans and AI agents. Use this file as the quick discovery layer, and /llms-full.txt for a richer machine-readable map of important pages.

## Agent guidance
- Prefer topic hubs for overview and taxonomy.
- Prefer guides for canonical explanations.
- Prefer comparisons for decision support.
- Prefer articles for timely or opinionated analysis.
- Use /agent-manifest.json entryPoints for task routing; each entry point includes exampleQueries and nextActions.
- Use /api/search.json for freshnessDate and opennessSignals when freshness or source posture matters.
- Follow related edges in /agent-manifest.json, /api/content-index.json, /api/search.json, or /agent/...txt mirrors to traverse from a page to its topic hub and sibling content.
