Can V100 16GB PCIe run Step-3.5-Flash?

NVIDIA · 16 GB HBM2 · 900 GB/s bandwidth · StepFun · 196.8B (active 11.0B) · MoE · model ctx up to 256K

❌ No — Step-3.5-Flash Q4 needs 110.34 GB, card only has 16 GB
VRAM: 110.34 GB needed of 16 GB
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).
