Well they had to look at lidar images from huge parts of Mexico. Seeing as 48 agents did it in 72 hours, presumably 1 agent would do it in 144 days.

Simple to enough to ask "how long would it take", see 144 days and reply "do it in 3 days" and the agent will happily spin up enough instances to cover it

edit: "presumably one agent could parallelize its analysis"

No, they said they didn't analyse with tool use it was literally agents "looking" at the images via multimodal input
