GenGenIK learns to generate whole-body configurations and trajectories from end-effector targets, scene geometry, and optional requests. Its masked model samples candidates that are refined numerically, using training examples generated with cuRobo. On simulated RB-Y1 bimanual-lift path tasks, it achieved 92.7% success@32, versus 42.7% for cuRobo, and reported 36.1 ms versus 940.0 ms to first valid solution. Held-out under-table pickup success was 0%.
