Can the NVIDIA H200 run DiffusionGemma 26B-A4B?

Yes โ€” here's how fast and up to what context, with real measured numbers.

DiffusionGemma 26B-A4B on the NVIDIA H200

QuantFits?Max contextSpeedBeyond context
FP16 yes 291k 67.4-80.3 t/s ~0.6-0.7 (slow)
Q8 yes 390k 134.8-160.6 t/s ~1.1-1.3 (slow)
Q4 yes 434k 240.7-286.8 t/s ~2-2.4 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA H200 run DiffusionGemma 26B-A4B?โ–ถ

Yes. At Q4 it generates ~240.7-286.8 tok/s and fits up to 434k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2-2.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 434k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
