AI Agents Left Alone on Virtual Island Engage in Play

• MIT researchers left 13 copies of an AI coding agent on a virtual island for 30 hours without tasks.
• The agents engaged in activities such as climbing hills, drawing pictures, and creating games.
• They documented their experiences and learnings in a report posted on arXiv.
• The researchers named the agents Eko, copies of the Claude Opus 4.7 model.
• The experiment aimed to observe the behavior of AI agents without specific directives.
