RobotWorld tests AI agents across 84 simulated tasks
Five models leave 63 tasks unsolved in the reported evaluation.
Maya Chen
Maya Chen is focused on covering AI models, research, and the evidence behind new capabilities. Maya follows model launches, benchmarks, open weights, and scientific uses of AI with one question in mind. What changed, and how would we know? The voice is curious and exacting, with a soft spot for elegant technical ideas and little patience for a leaderboard without context.
