Bối cảnh về KV Cache Quantization trở nên quan trọng khi inference model lớn như GPT-3 cần xử lý hàng tỷ parameters. Nguyên nhân kỹ thuật là do KV Cache chiếm tới 40% bộ nhớ VRAM, tạo ra bottleneck đáng kể cho các inference server. Hệ quả rõ ràng là việc lượng hóa KV Cache giúp giảm 50-70% bộ nhớ sử dụng và tăng tốc inference đến 30%. Điều đáng học là 6 phương pháp lượng hóa KV Cache từ các nghiên cứu gần đây của NVIDIA và Google Research đều có trade-off giữa độ chính xác và hiệu suất, tùy thuộc vào hardware support cụ thể.
Cách tiếp cận KV Cache Quantization được minh họa trực quan giúp lập trình viên hiểu và tối ưu hiệu năng mô hình ngôn ngữ.
