VarRate Cuts Long-Context Memory by Varying KV-Cache Compression Token by Token
The training-free method targets the key-value cache, the dominant memory cost of long-context inference, without the structural limits of token-selection or fixed-rate approaches.
A new paper introduces VarRate, a training-free method for variable-rate compression of the key-value cache in long-context large language model (LLM) inference. The key-value (KV) cache stores the attention state for every token in the con…

The Inference-Cost Efficiency Race
Techniques that cut tokens generated and KV-cache memory per query will keep compressing the marginal cost of serving reasoning models, making inference efficiency a recurring competitive axis alongside raw capability.
