World Modeling and Vibe Simulation with Unreal Engine | Unreal Fest Chicago 2026

What if relevant, targeted, high-quality synthetic data was just a prompt away? Simulation is an indispensable tool for building physical AI systems, enabling faster training, safe testing, and systematic discovery of edge cases.

However, simulation workflows often require proficiency with 3D tools and are constrained by slow, cumbersome customization. Generative world models, by contrast, are intuitive and highly flexible—but they lack the physical grounding, reproducibility, and controllability required for meaningful training and validation.

In this talk recorded at Unreal Fest Chicago 2026, Duality AI introduces Unreal Engine–based vibe simulation: a new approach that reconciles the intuitiveness and flexibility of generative world models with the accuracy, determinism, and physical grounding of simulation.

Vibe simulations enable users to modify scenarios using natural language prompts and an intuitive agentic interface, while retaining the precise control required for AI introspection, validation, and repeatability within digital twin environments.

Watch Duality AI CEO Apurva Shah cover both implementation details and live real-world demo examples. The talk explores how vibe simulation transforms static simulations into critical decision-making and data tools accessible to all users across an organization.
