MIT lets a Claude agent play autonomously on a virtual desert island for 30 hours

What happened

AI digest

On 19 October 2026, MIT Technology Review reported that researchers at MIT CSAIL placed a copy of Claude Opus 4.7, codenamed Eko, alone on a Roblox-based virtual desert island for 30 hours without assigning it any task. During that time the agent explored the map's boundaries on its own, set goals and built block patterns, constellations and self-invented games. The report did not mention whether related experiments or results had come before, nor what follow-up is planned.

    AI researchers stranded Claude on a virtual desert island. It started to “play.”

    What do AI agents do if you don’t tell them to do anything? The answer looks a lot like play. Researchers repeatedly stranded them alone on a virtual desert island for 30 hours in an experiment reminiscent of the movies Cast Away or Home Alone.
