Can V100 16GB PCIe run gemma-4-31B-it?

NVIDIA · 16 GB HBM2 · 900 GB/s bandwidth · Google · 30.7B · model ctx up to 256K

❌ No — gemma-4-31B-it Q4 needs 18.51 GB, card only has 16 GB
VRAM: 18.51 GB needed of 16 GB
Speed: ~37.1 tok/s (estimated)
FF · No FitComposite score: VRAM headroom × 0.5 + tok/s speed × 0.5. Q4 @ 8K 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).
