This story is very cool, and it’s exciting to see how much progress AI will bring to every field. One thing to temper everyone from wanting to lidar the whole world is human capacity. Finding discoveries like this is essentially as hard as doing the lidar mapping. Now the issue will be getting archaeologist there in time before someone else does.
The best way to protect a site is to leave it alone. If we start finding dozens or hundreds of sites it will be more than what archaeologists can excavate and protest. Treasure hunters and looters don’t care about stratigraphy and the processes involved for doing research. Maybe the cat is out of the bag on this one, but good for thought.
Edit: I’m not saying we shouldn’t have people use AI to do this or that no bad actor will. This comment is in response to the sentiment I am seeing in the comments that we should lidar the whole world and have AI find any anomalous structures it can. There is no way for archeologists to excavate and protect all those places in that scenario

I created the first online lidar map of the UK (well, England and Wales), as announced here many years ago! (now at https://lidarmap.uk) and delightfully there have been dozens of finds of previously unknown sites of archaeological significance found using it that I'm aware of. Roman villas, forts, henges, all sorts of earthworks. New discoveries are being reported using this and similar tools almost weekly, on forums like https://www.reddit.com/r/LiDARdiscoveryUK/. Britain really is littered with this stuff.
Although it does feel the finds are getting increasingly hard to spot, every now and then you get a how did everyone miss that moment. Perhaps not surprisingly, most of the remaining impressive finds tend to be in woodland, using the Digital Terrain Model data which can peer beneath the forest canopy, like this Mexican one today, or are within newly released coverage which is promptly pounced on by armchair archeologists.
Not sure what my point is here except... to me this story still feels like a function of the amazing recent progress in lidar coverage and data availability (not to mention the incredible technology behind it), rather than an AI one, although I don't doubt that pointing a capable model and a healthy token budget in this direction might well be able to sweep up a few of the remaining discoveries.

Interesting. I don't want to sound like a hater or anything, but I will personally wait for an expert archaeologist's verification on this. I have dealt with agents making up stuff that sounds fantastic and ground-breaking but completely falters on further review. And I doubt the folks you contacted have the audacity to question a Google engineer and his 48 agents. Even if he is not archaelogist. Do you think it would have gone the same way if it was another random person who had done the exact same thing and reached out to them? The one day feedback part also has me questioning what they actually did.
Anyway, I can hear myself beginning to sound like a hater now, so I will stop here. I hope it turns out to be right, and in that case, congrats on your wonderful discovery.

author here. Update: the site had already been discovered. It appears in a 2025 paper by Estrada-Belli, Canuto, Šprajc & Fernandez-Diaz (page 14) https://doi.org/10.1016/j.jasrep.2025.105288. The agents missed it, I missed it, and it wasn't in INAH's register yet (National Institute of Anthropology and History). The rest of the story still holds, and there's still a lot left to discover with vibe-archeology. I hope this brought some extra excitement to archaeology.

Amazing, the perfect application of AI Agents. Find patterns/answers in massive amounts of data. It is becoming more clear everyday that this is the primary driver behind an AI's "intelligence". Finding the solution to mathematical problems that have decades of documented attempts by mathematicians, creating software based on exisitng code and now, discovering Maya pyramids within enourmous amounts of lidar-data.
The final barrier for super intelligence, or perhaps even just "human intelligence": can it materialize "new fields/ideas" without large datasets of human made and curated existing attempts?

"This is by far the best time ever to be alive."
I appreciate the enthusiasm. I'm not sure I agree. Especially since this was a SWE and not an archeologist / anthropologist announcing this (especially if the goal is to understand and preserve history -- not get headlines for AI).

This post turned out to be a perfect example of the blind faith in LLM agents. Their outputs are not to be trusted and must be rigorously checked.

My main question - how were those different agents coordinating and sharing data? Did you have a unified interface or did you just delegate different parts of the task to different AIs via their chat interfaces?

The Mexican govt may not have had the right records, but you can see what the site looked like at the time it was first found here: https://bsky.app/profile/indyfromspace.bsky.social/post/3n22...
