Audio Token Attention Is Predictable Before the Language Model Runs

A large audio language model (LALM) turns a minute of speech into 750-1,500 tokens and prefills every one. Image-token pruning often cuts after the language model's first layers, where image tokens draw little attention. Audio tokens draw much more attention there, and their ranking is still far from final, so audio ne...

AS$^2$D: Accelerating On-Demand Audio Understanding on Mobile Devices

Speculative decoding accelerates autoregressive generation by using a smaller drafter to propose tokens for batched verification by a larger target. However, conventional speculative decoding couples drafting to the target's evolving verified prefix, serializing drafting and verification. We ask whether this dependency...

OmniCache: Multidimensional Hierarchical Feature Caching For Diffusion Models

OmniCache is proposed, a unified hierarchical caching framework that performs multidimensional feature reuse through Token Cache, Frame Cache, Block Cache, and Layered Cache that reuses spatial features in temporal layers and temporal features in spatial layers, while Layered Cache captures cross-step redundancy at the...
