🏆 PhysBrain 1.5-8B scores 72.5 across 28 embodied-understanding benchmarks, ranking #
1# among the evaluated open-source models and leading 14 tasks. The compact 2B reaches 66.6.
🧭 Both models cover spatial perception, 3D reasoning, embodied planning, grounding, affordance, and trajectory reasoning.
🦾 They generate end-effector trajectories and predict future states as aligned RGB, depth, and robot masks.
🧠 Built on Qwen3-VL, PhysBrain 1.5 models language, spatial outputs, actions, and future states as tokens within one autoregressive backbone. No task-specific heads.
