About the workshop

Making world models actionable, physically grounded, and deployable

World models predict how an environment evolves, optionally conditioned on an agent's actions, and can be rolled out to imagine future observations and outcomes. For physical-AI systems — robots, autonomous vehicles, and embodied agents — this capability is central: an agent that can simulate its world can plan, learn from imagined experience, and handle situations missing from its training data.

Progress now spans latent-dynamics models for control, interactive and generative video simulators, foundation world-model platforms, and closed-loop autonomous-driving simulation. Model-based RL, generative simulation, and video prediction are all converging on controllable models of the world — but in separate communities. This one-day workshop brings them together to ask what world models must deliver to serve as a deployable computational substrate for physical AI.

"An agent that can simulate its world can plan, learn from imagined experience, and act where its training data runs out."
The premise of world models for physical AI — from generative simulators to latent, planning-friendly state spaces.
Scope

Topics we invite

Talks, papers, and discussion spanning the pipeline from data and representations, through evaluation, to planning and control.

Representations & architectures

Latent vs. pixel/video models, JEPA embeddings, identifiable latents, omnimodal models, 3D and contact dynamics.

World models for action

Model-based RL, planning and control, learning in imagination, forward and inverse dynamics, world-action models.

Generative simulation

World models as data generators and interactive closed-loop simulators for robotics and driving; sim-to-real and real-to-sim.

Evaluation

Measuring whether world models are physically correct, causally faithful, and useful for downstream control; benchmarking robustness and generalization.

Scaling & foundation models

Data, compute, and generalization of large pretrained world models across embodiments and domains.

Safety & broader impact

Reliability, safety, and the broader impact of world models that drive real physical systems.

The debate

Open questions we'll take positions on

The program — talks, a panel, and a closing debate — is organized around concrete, contested questions.

1

What does "correct" mean?

Can we agree on benchmarks that measure physical consistency and downstream control utility — not just pixel fidelity? For closed-loop simulators, should evaluation preserve policy rankings and real-world failure modes?

2

Pixels vs. latents

Should world models predict in observation space or in abstract latent space? When are inspectable rollouts necessary, and when are identifiable, low-dimensional latents enough for planning and control?

3

Controllability & long horizons

How do we keep rollouts action-controllable and physically consistent over long horizons — preserving object identity, contact, causality, and state under repeated interventions?

4

Sim-to-real & real-to-sim

When can a generative world model replace or augment a physics or reconstruction-based simulator for training and evaluating deployable policies?

5

Scaling laws

Do world models for physical AI follow favorable scaling laws, and what multimodal data unlocks generalization to new embodiments, action spaces, and domains?
