This repository contains the model used in the paper [Aether: Geometric-Aware Unified World Modeling](https://arxiv.org/abs/2503.18945).

Aether addresses a fundamental challenge in AI: integrating geometric reconstruction with generative modeling 
for human-like spatial reasoning. Our framework unifies three core capabilities: (1) **4D dynamic reconstruction**, 
(2) **action-conditioned video prediction**, and (3) **goal-conditioned visual planning**. Trained entirely on 
synthetic data, Aether achieves strong zero-shot generalization to real-world scenarios.
