How much memory does Qwen2.5 14B Instruct need?

Qwen2.5 14B Instruct is a 14B dense model built for coding, chat. The weights alone take 11 GB at Q4_K_M; add context and the OS, and it belongs in the 24 GB memory class. Every number below comes from the ModelFit engine — speeds are estimates, labeled est., because we do not benchmark hardware ourselves.
