Researchers have introduced A-PACK, a novel two-stage framework designed to reduce the computational costs associated with omni-modal Large Language Models (LLMs). This method defers audio pruning until query-conditioned multimodal interactions become relevant, addressing the significant prefill and KV-cache expenses of processing long multimodal sequences. A-PACK prioritizes audio information density and uses local audio-visual dynamics for more effective visual selection, leading to substantial reductions in computational operations and improvements in decoding throughput on benchmarks using Qwen2.5-Omni models.
