It started to “play.”","summary":"Researchers stranded copies of Claude Opus 4.7, nicknamed Eko, alone on a virtual desert island for 30 hours. The agents set their own goals, invented games such as a basketball variant and \"the floor is lava,\" and logged their activity in text files that served as long-term memory. Agents that had played on the island later outperformed fresh copies on a task, and deleting lines from their memory files degraded that performance.
