KVarN: Native vLLM KV-cache quantization back end by Huawei

KVarN is a new vLLM KV-cache quantization backend from Huawei. It aims to significantly reduce memory usage for large language models by quantizing the key-value cache, enabling larger context windows or more models on the same hardware. This development directly benefits AI developers by offering a practical solution to memory constraints in LLM inference.
