# Viral claim that AI agents found an unmapped Maya site turns out to be a rediscovery of a site published in 2025

A Nov 10, 2026 blog post by Pietro Miotti, "My AI agents found an unmapped Maya site?", reached 1,024 points on Hacker News: 48 AI agents reviewing NASA lidar data flagged a Maya site in Mexico not in INAH's register within about 72 hours. On Nov 11 the author updated the post: the site had already been mapped in Estrada-Belli et al. 2025, so the agents "rediscovered it rather than discovered it"; The Verge ran "No, AI agents did not discover a previously unknown Maya site".

## Key facts
- Method as described: brainstorming with Gemini, ChatGPT, Claude and Grok, then 48 agents reviewing lidar tiles; the post does not say which model did the image analysis
- Update (Nov 11): site already in Estrada-Belli et al. 2025; the author says 'the rest of the story still holds'
- Reach: 1,024 points on Hacker News (Nov 11)

## Why it matters

A typical viral "AI discovers X" story: a real capability (fast triage of lidar data) presented as a discovery before a literature check.
