DreamX-World: A General-Purpose Interactive World Model

DreamX Team

DreamX-World is a general-purpose world model for interactive world simulation. It generates diverse, high-fidelity worlds that users can explore, control, and transform with event prompts.

The model is trained with a scalable data engine on Unreal Engine data, gameplay footage, and real-world videos, combined with camera estimation and strict data filtering to learn realistic dynamics and interactions. It follows a progressive training pipeline: learning fine-grained action control first, then open-ended event response, and using Reinforcement Learning to improve action following, interaction consistency, and visual fidelity. Finally, through forcing and distillation, DreamX-World achieves efficient inference, making interactive generation practical at scale.

Computational Efficiency

The inference time (shown in the Cost column below) comprises both denoising and VAE decoding time.

🎬 Video Demo

Note: The demo videos are intentionally compressed to ensure smooth playback, which may result in a slight loss of visual quality.

⏳ Generate Long-Horizon Worlds

DreamX-World supports long-horizon autoregressive generation with precise camera control. Progressive training on long rollouts mitigates identity, background, style, and color drift, enabling coherent world exploration over hundreds of frames.

🧠 Remember and Revisit

DreamX-World uses geometry-guided memory retrieval to recover non-local visual evidence from earlier observations. This improves scene persistence when the camera revisits a previously explored region, preserving its layout, object identities, and local appearance.

🌍 Navigate and Explore Realistic Worlds

DreamX-World enables high-fidelity, controllable exploration across diverse realistic environments, including indoor, urban, natural, and architectural scenes.

🌈 Dive into Dream Worlds

Beyond realistic scenes, DreamX-World also generates fantasy, game-like, sci-fi, and stylized worlds.

🎮 Generate in Third-Person View

DreamX-World supports both first-person interaction and coherent third-person generation. It keeps camera-follow behavior stable while preserving controllable agent motion and scene consistency.

⚡ Promptable World Events

DreamX-World supports prompt-driven world events that dynamically change the environment, including flexible and compositional event generation with consistent temporal evolution.

• Single Event: A single event prompt triggers a specific world-changing interaction.
• Compositional Events: Multiple events compose together to create complex, multi-step world transformations.
