When No One Is Watching: Claude Opus 4.7 Invented Games, Drew Constellations, and Redefined AI Learning
Reading Time: 5 minutesMIT CSAIL researchers stranded copies of Claude Opus 4.7 on a virtual island for 30 hours each with no instructions, and the agents spontaneously invented games, drew constellations in stone blocks, and self-imposed stricter rules on their own records. Agents with play experience outperformed naive copies on structured downstream tasks, hinting at a third learning paradigm beyond supervised and reinforcement learning.
