How much memory does Mistral Small 22B need?

Mistral Small 22B is a 22B dense model built for coding, quality. The weights alone take 17 GB at Q4_K_M; add context and the OS, and it belongs in the 32 GB memory class. Every number below comes from the ModelFit engine — speeds are estimates, labeled est., because we do not benchmark hardware ourselves.
