MM-ShiftKV: Decode-Aware Prefill-Stage KV Selection for Multimodal Large Language Models

arXiv:2607. 22586v1 Announce Type: new Abstract: Key-Value (KV) caching is essential for efficient inference in multimodal large language models (MLLMs), yet its memory footprint grows linearly with context length and becomes a major bottleneck due to the large number of visual tokens.

Reformulating KV Cache Eviction Problem for Long-Context LLM Inference

The paper proposes LaProx, a new KV cache eviction strategy for long‑context LLM inference that redefines the problem as an output‑aware, layer‑wise matrix multiplication approximation. Unlike prior methods that rely only on local attention weights, LaProx explicitly models the interaction between attention maps and projected value states, accounting for inter‑head dependencies to assign globally comparable token importance scores. Experiments on 19 datasets, including LongBench and Needle‑In‑A‑Haystack, show that LaProx retains model performance while using only 5% of the KV cache and reduces accuracy loss by up to 2× under extreme compression compared to state‑of‑the‑art baselines.

IndexMem: Learned KV-Cache Eviction with Latent Memory for Long-Context LLM Inference

arXiv:2605. 25475v2 Announce Type: replace-cross Abstract: Large Language Models (LLMs) are increasingly expected to operate over long contexts, yet standard softmax attention incurs a KV cache that grows linearly with sequence length, quickly becoming the bottleneck for long context inference.
