Can Gaudi 3 128GB run Step-3.5-Flash?

Intel · 128 GB HBM2e · 3276 GB/s bandwidth · StepFun · 196.8B (active 11.0B) · MoE · model ctx up to 256K

Yes — the Gaudi 3 128GB (128 GB HBM2e) can run Step-3.5-Flash. At Q4 with the default 8K context it needs ≈ 111.44 GB VRAM (weights 108.24 GB + KV cache 2.2 GB + 1 GB runtime overhead), which fits within 128 GB. Decode at Q4/8K: ≈ 189.5 tok/s (estimated, batch 1). FP16 needs ≈ 396.8 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	110.34 GB	Yes	189.5 est.
Q4	8K default	111.44 GB	Yes	189.5 est.
Q4	32K	118.04 GB	Yes	189.5 est.
FP16	4K	395.7 GB	No	15.6 est.
FP16	8K default	396.8 GB	No	15.5 est.
FP16	32K	403.4 GB	No	15.0 est.

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).
