can it run
Comfortably. 32GB of memory against a 5GB working set leaves headroom for context, the OS, and anything else you're running.
weights 3.3GB + KV cache 0.53GB at 4k context vs ~32GB usable → full. 3.8 GB needed of 32 GB usable — headroom for context
computed roofline: 1792 GB/s × 0.55–0.80 efficiency window / 3.3GB (Q4_K_M) — bands, never points. Small models (under ~4.5B) run BELOW these bands — kernel-launch overhead keeps them from saturating bandwidth (measured against community medians, 09-06).
