Claude agents invented games after 30 hours alone
Left alone for 30 hours, copies of Claude Opus 4.7 created their own goals and games instead of waiting for instructions, suggesting a way for AI systems to learn without human examples or rewards. In a Roblox-like island, one agent arranged blocks into drawings and constellations, while another invented basketball and “the floor is lava.” The researchers call this playful learning, but their paper has not yet been peer-reviewed.
