LMCache: Lower LLM Performance Costs in the Enterprise
summary
Claims a practical open source KV-cache layer that reduces Time to First Token and increases throughput by reusing attention tensors instead of recomputing long contexts. Integrates with vLLM and KServe, runs on Kubernetes, and offloads GPU KV tensors to CPU, local disk or backends like Redis and S3 with RDMA/GPU‑to‑GPU sharing. Shows a working library (permissive license, PyTorch‑foundation) and describes batching, chunking and async transfer optimizations that lower latency and cost.
