can it run
Only with compromises. 16GB is below the 18GB working set — expect a lower quant, offloading, or heavy swap. Possible, not pleasant.
weights 14GB + KV cache 0.19GB at 4k context vs ~16GB usable → tight. 14.2 of 16 GB usable — keep context modest
computed roofline: 644.6 GB/s × 0.55–0.82 efficiency window / 2.1GB (Q4_K_M) — bands, never points.
MoE: file is 14GB (that decides fit) but only ~3B of experts activate per token (~2.1GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
