Stickblade Arena is a new benchmark where LLM agents control ragdolls in a 2D physics sword-fighting simulator, testing multi-turn tactical reasoning, spatial awareness, and real-time decision-making under adversarial pressure. Early results reveal capability gaps: DeepSeek R1 dominates melee but fails at bow due to time limits, and small models excel at close-range fighting.
PhyMotion proposes a physics-grounded reward system that evaluates kinematic plausibility, contact consistency, and dynamic feasibility of human motion in generated videos, achieving stronger correlation with human judgment and improving motion realism in RL-based post-training.
