Wow. That's cool.

Researchers just released World, an open-source Unreal Engine 5 simulator for training and testing LLM and VLM agents in realistic 3D environments.

The platform supports RGB, depth, and segmentation sensors, along with navigation, vehicles, pedestrians, robots and procedural city generation.

It's built with a Gym-like Python interface, it allows AI agents to learn physical and social reasoning in complex virtual worlds before real world deployment.

We're moving from AI that only understands information to AI that can perceive, reason and act inside realistic simulated environments.

@SciTechera @Lianhuiq Thanks for sharing our work!🔥

Also check out the latest development on SimWorld Studio

Environment generation is the missing scaling axis for embodied AI.

Introducing SimWorld Studio: a self-evolving factory for endless interactive 3D env where agents act, fail & learn.

Env-agent co-evolvution improves navigation success 50% → 90%.

From a prompt, our SimCoder writes code to automatically build an interactive world. Agents train inside it. And their performance shapes the next world.
