AI Summary
AlayaWorld v1.1 introduces major architectural revisions for interactive long-horizon world modeling, including a new 3D point-cache renderer and redesigned conditioning pipeline.
Excerpt
This report presents an improved version of AlayaWorld. While the backbone architecture, chunk-wise autoregressive generation scheme, and training data remain unchanged from the previous release, we substantially revise how conditioning signals are represented and integrated into the model. The new design is guided by a simple principle: conditioning signals should match the generated content as closely as possible in both latent representation and temporal structure. To this end, we make two ma
