NVFP4 KV Cache
A novel 4-bit floating-point quantization format for KV cache optimization in large language models.
About
NVFP4 KV cache is a new format designed to significantly enhance the performance of large language models (LLMs) during inference, particularly on NVIDIA Blackwell GPUs. It reduces the KV cache memory footprint by up to 50%, enabling doubled context budgets, larger batch sizes, and longer sequences with minimal accuracy loss (<1%). This optimization addresses the memory bandwidth bottleneck in the decode phase, leading to reduced latency and improved throughput.
