Can the Surface Laptop Ultra (24GB) run FLUX dev fp8?

STRETCH

Only with compromises. 24GB is below the 29GB working set — expect a lower quant, offloading, or heavy swap. Possible, not pleasant.

~3–7.7 tok/s

weights 23GB + KV cache 2GB at 4k context vs ~22GB usable → offload-partial. 25.0 GB vs 22 GB usable — partial CPU offload, expect large speed loss

computed roofline: 273 GB/s × 0.25–0.65 efficiency window / 23.0GB (Q4_K_M) — bands, never points.
