Can DGX Spark (GH200 480GB) run gemma-4-31B-it-FP8-block?

NVIDIA · 480 GB LPDDR5X · 500 GB/s bandwidth · RedHatAI · 31.3B · model ctx up to NoneK

Fit & speed by quant and context

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).
