Can H100 80GB SXM5 run DeepSeek-V4-Flash?

NVIDIA · 80 GB HBM3 · 3350 GB/s bandwidth · DeepSeek · 158.1B (active 13B) · MoE · model ctx up to 1000K

No — DeepSeek-V4-Flash at Q4 needs ≈ 89.25 GB even at 4K context, beyond the H100 80GB SXM5's 80 GB HBM3. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 365.7 tok/s (estimated, batch 1). FP16 needs ≈ 319.8 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	89.25 GB	No	376.4 est.
Q4	8K default	90.55 GB	No	365.7 est.
Q4	32K	98.36 GB	No	309.9 est.
FP16	4K	318.5 GB	No	8.1 est.
FP16	8K default	319.8 GB	No	8.1 est.
FP16	32K	327.6 GB	No	—

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).
