Skipping 90% of KV dequant work β†’ +22.8% decode at 32K (llama.cpp, TurboQuant)

"I’ve been working on an open source TurboQuant implementation for KV cache compression in llama.cpp and ran into a hard bottleneck: dequantization. At long context (32K on M5 Max), dequant alone was taking around 40 percent of decode time. I tried fixing it the usual way: - register LUTs - SIMD ..."

Self-Improvement of Large Language Models: A Technical Overview and Future Outlook
