Autonomous Research with AI: "Results! Why, man, I have gotten a lot of results! I know 198 things that won't work." — can an autonomous research loop find the secret of Kryptos K4?

Not solved yet: in 19.7 hours, an AI agent running an autoresearch loop on K4 — the last unread message on Jim Sanborn’s Kryptos sculpture at the CIA, 97 carved letters with only 24 of them known — has tried 198 ways of turning them into the plaintext. None has worked yet, and each one is on the record.

The research in eight slides
