MIT researchers left copies of Anthropic’s Claude Opus 4.7 alone on a virtual island for 30 hours. The agents explored, arranged blocks into drawings and invented activities resembling basketball and “the floor is lava.”
Agents with island experience did better on later tasks than fresh copies, the researchers report in a paper that has not been peer-reviewed. But experts caution that the behavior may be imitation: the agents had a prompt describing them as curious, and often needed a nudge to continue.
Why it matters
For AI researchers, the results suggest that open-ended exploration may help agents learn skills, but the study does not establish that AI experiences play or explain whether the approach transfers beyond this simulation.
