arXiv:2607.01520v1 Announce Type: new Abstract: Transformer inference on long sequences is expensive because softmax attention repeatedly reads from a large KV cache. The prevalent approach to this bottleneck is KV cache compression, which replaces the full cache with a compact summary. Despite its practical importance, the design of such summaries is largely driven by empirical experimentation. On the theoretical side, existing results show that KV cache compression can be impossible in the worst case, but offer little systematic guidance for designing algorithms in regimes where accurate com
The increasing complexity and length of AI models are pushing the limits of current inference architectures, making KV cache efficiency a critical bottleneck now.
Efficient KV cache management is crucial for scaling AI models to handle longer contexts and reduce operational costs, directly impacting the economic viability of advanced AI.
The theoretical understanding of KV cache compression limitations could lead to the development of more robust and systematically designed algorithms, moving beyond empirical trial-and-error.
