16-bit to 3.5-bit compression

This page discusses advanced techniques in compressing Key-Value (KV) caches for Large Language Models (LLMs), focusing on the transition from traditional 16-bit representations to more compact formats, like 3.5-bit. The objective is to increase context window sizes and enhance inference speeds by leveraging efficient data compression methods.
