Yes — the DGX Spark (GH200 480GB) (480 GB LPDDR5X) can run NVIDIA-Nemotron-3-Nano-4B-BF16. At Q4 with the default 8K context it needs ≈ 3.24 GB VRAM (weights 2.2 GB + KV cache 0.04 GB + 1 GB runtime overhead), which fits within 480 GB. Decode at Q4/8K: ≈ 79.5 tok/s (estimated, batch 1). FP16 (≈ 9.04 GB) also fits, at ≈ 21.9 tok/s (estimated). Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
