Make Each Token Count: Towards Improving Long-Context Performance with KV Cache Eviction

Ngoc Bui, Hieu Trung Nguyen, Arman Cohan +1

The key-value (KV) cache is a major bottleneck in long-context inference, where memory and computation grow with sequence length. Existing KV eviction methods reduce this cost but…
