How much memory does Granite Switch 4.1 30B need?
Granite Switch 4.1 30B is a 30B dense model built for chat, decisions, safety checks. The weights alone take 21 GB at Q4_K_M; add context and the OS, and it belongs in the 36 GB memory class. Every number below comes from the ModelFit engine: speeds are estimates, labeled est., because we do not benchmark hardware ourselves.
KV = fp16 estimate (q8_0 cache roughly halves it). "Comfortable" = weights + KV within the engine's tiered budget (~70-85% of memory).
