Lynx: Progressive Speculative Quantization for accelerating KV Transfer in Long-Context Inference
arXiv:2607.01831v1 Announce Type: cross Abstract: Long-context inference is increasingly common in large language model (LLM) serving, driven by retrieval-augmented generation and agentic systems. In disaggregated inference, these workloads require transferring large Key-Value (KV) caches across the network, where decoding cannot begin until the transfer completes. Recent KV quantization techniques reduce data volume and alleviate this bottleneck, but existing schemes fail to achieve both low network-exposed latency and high inference accuracy. We challenge the assumption that the KV cache is
The increasing complexity of large language models and widespread adoption of retrieval-augmented generation and agentic systems necessitates more efficient data transfer and inference methods.
Improving the efficiency of KV cache transfers is critical for scaling LLM inference, directly impacting the cost, speed, and responsiveness of AI applications.
This advancement promises to reduce network latency and data volume requirements for long-context LLMs, making their deployment more feasible and cost-effective in disaggregated inference architectures.
