KV caching is one of the biggest ROI optimizations: 5-10x speedups
Sujee argues KVCache is probably one of the biggest ROI optimizations in doing inference, because creating tokens is expensive, especially one at a time. Once you generate a token, it doesn't change, so there's no need to keep regenerating the same token over and over again — the idea is to cache tokens so the next time you need to look up, you don't have to regenerate it, you just look up the cache. Nebius has seen speedups anywhere from 5x to 10x, not just 5 to 10 percent.
