can it run

Can the Surface Laptop Ultra (24GB) run DeepSeek-V4.1-Flash?

NO

No. 24GB of memory can't hold the 212GB working set this model needs. A smaller quant or a bigger machine is required.

~2.7–7 tok/s (active-expert estimate)

weights 168.9GB + KV cache 2GB at 4k context vs ~22GB usable → no. 170.9 GB vs 22 GB usable — does not fit

computed roofline: 273 GB/s × 0.25–0.65 efficiency window / 25.3GB (Q4_K_M) — bands, never points.

MoE: file is 168.9GB (that decides fit) but only ~82.8B of experts activate per token (~25.3GB streamed) — band below is the active-expert estimate, optimistic; community MoE rows run several× the naive bandwidth math
