Operators trade repeated prompt computation for shared host-memory capacity and KV-transfer overhead.** By [Ryan Merket](https://runtimewire.com/author/ryan-merket) · Published Primary source: [The Cloudflare Blog](https://blog.cloudflare.com/kv-cache-exposure-remediation/) ## Why it matters Shared prefix reuse can cut repeated prompt computation when requests arrive at different serving instances. Operators must weigh that potential saving against host-memory reservations, transfer copies and the GPU KV capacity still required to serve cache hits. TensorRT-LLM's [v1.4.0rc1 release candidate](https://github.com/NVIDIA/TensorRT-LLM/releases?ref=runtimewire), released October 22nd, lists an integration with Mooncake Store for sharing KV-cache prefixes across serving instances. Mooncake's [project update](https://kvcache-ai.github.io/Mooncake/?ref=runtimewire) dates the merge to October 10th.… When you purchase through links in our articles, [we may earn a small commission](https://runtimewire.com/affiliate-monetization-standards).
