I got 9/10 as a human, so I guess I might not be a human... :)

Given the rise of AI agents, I created this concept art of what a CAPTCHA trivial for LLMs but difficult for humans would look like.

neat idea. one thing that helps against scripted solvers is rotating challenge type by session risk score, not random only. we saw static challenge pools get mapped fast once traffic passed a few thousand/day.
