HCAttention: Extreme KV Cache Compression via Heterogeneous Attention Computing for LLMs
HCAttention combines key quantization, CPU value offloading, and cumulative-attention eviction to run long-context LLMs with 12.5% to 25% of the GPU KV cache while keeping LongBench accuracy close to full attention.
