In the opposite direction are works like SLIM, JEPA-WAM, and ω-EVA, which bet on bidirectional masking, isolation mechanisms, and test-time refinement—relying on structure rather than scale. The only truly colliding judgment between the two paths: Some work explicitly argues that switching logic should be delegated to a planner, not learned end-to-end by the policy, directly contradicting the idea that 'pure scale needs no specialized mechanisms.'\n\nAnchor for review six months later: No need to wait for open-sourcing or replication; just look at the next checkpoint—whether improvisational error correction continues to become more frequent and refined, and whether task sets and success rates keep climbing. If the trend breaks, the persuasiveness of this path breaks; if it keeps rising, this is the GPT-3 narrative unfolding in robotics."
