The KV Cache Is Your Inference Bill: Bytes Per Token, From Three Real Configs
An inference budget is a memory-traffic budget wearing a compute costume. Everyone sizes clusters in FLOPs and negotiates GPU-hours, then wonders why cost per token doesn't fall. At batch one, a decoder touches every weight and the whole KV cache to emit one token. Arithmetic is the cheap part. The…
