Embodied foundation models are expected to benefit from data scaling like large language models, but face a much tighter data bottleneck. Teleoperated real-robot trajectories remain the dominant pretraining source due to their precise action supervision and embodiment alignment, yet their scalability is limited by high collection cost, acquisition difficulty, and low behavioral and environmental diversity.

The paper introduces a reinforcement learning post‑training scheme that trains robot world models on their own autoregressive rollouts, using a contrastive RL objective adapted from diffusion models. It also proposes a training protocol that compares multiple variable‑length futures, a multi‑view visual fidelity reward, and demonstrates state‑of‑the‑art rollout fidelity on the DROID dataset, outperforming baselines on LPIPS, SSIM, and human preference tests.

ZimaBlue is a scalable framework that learns generalizable World Action Models (WAMs) from large-scale egocentric videos. It follows a three-stage curriculum: causal video pre‑training, video‑action mid‑training with a unified action representation, and final specialization to a target robot. The system employs an asynchronous Slow‑Fast architecture to enable real‑time 30 Hz action prediction, achieving a jump in real‑robot zero‑shot success from 36.1% to 77.8% when leveraging over 120,000 hours of embodied video.

The paper introduces the World-Ego Model (WEM), which separates an embodied video into a background‐only world component and an ego component comprising the robot and manipulated objects. By using role‑conditioned attention and asymmetric query budgets for state prediction, coupled with a semantic‑routed mixture‑of‑experts diffusion generator, WEM disentangles the generation of scene evolution and instruction following. The authors also release HTEWorld, a large dataset of 125K training clips and 300 evaluation trajectories for long‑horizon navigation‑manipulation tasks, and demonstrate that WEM outperforms prior methods on this benchmark.
