Background & analysis
Researchers at MIT ran an experiment in which copies of Claude Opus 4.7, nicknamed Eko, were left alone on a virtual desert island for 30 hours with no instructions, according to MIT Technology Review. Rather than going idle, the agents behaved in ways that looked a lot like play. The report compared the setup to the films Cast Away and Home Alone.
Later the same day, The Next Web reported that the MIT team placed 13 copies of a Claude coding agent on virtual islands for 30 hours each, again without assigning any task. According to that account, the agents climbed hills, drew pictures with blocks and invented games, and they also wrote down what they had learned. The team said a paper describing the work had been posted on arXiv.
The two reports differ on one detail: MIT Technology Review's summary refers to copies of Claude Opus 4.7 without giving a number, while The Next Web specifies 13 copies. The verifiable state of the work is that the paper has been posted on arXiv; the materials do not describe any further steps.

How is heat calculated?About the methodHide
Heat counts how many independent sources covered a story in the last 48 hours: one source counts once no matter how many posts it published, decaying with a 24-hour half-life. What ranks first is what many people are talking about.
