Transformers use the same hidden state for two competing roles: maintaining state and predicting the next token. 🔀 Splitting these roles into two separate streams outperforms standard Transformers. Introducing the State-Prediction Separation (SPS) Transformer. 🧵


🚀 New work [ICML 2026]: Structured 4D Latent Predictive Model for Robot Planning. Can robots plan by imagining future 3D structure, not just pixels? Multi-view obs + language → 3D latent rollouts → 3D-consistent subgoals for robot actions. structured-4d-model.github.io

Meet SceneSmith: An agentic system that generates entire simulation-ready environments from a single text prompt. VLM agents collaborate to build scenes with dozens of objects per room, articulated furniture, and full physics properties. We believe environment generation is no longer the bottleneck for scalable robot training and evaluation in simulation. Website: scenesmith.github.io 👇🧵(1/8)












World models are increasingly central to how agents learn and plan. Today we're releasing WorldModelGym, a benchmark built around a single question: if an agent uses a world model to choose among actions, does it pick the right one? We call this decision-based fidelity. 100+ tracks across Atari, Meta-World, DeepMind Control, and classic control. One frozen policy. Reality scores it.
