Can H200 141GB SXM5 run Inkling?

NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth · Thinking Machines · 975.0B (active 41.0B) · MoE · model ctx up to 1024K

No — Inkling at Q4 needs ≈ 541.35 GB even at 4K context, beyond the H200 141GB SXM5's 141 GB HBM3e. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 14.2 tok/s (estimated, batch 1). FP16 needs ≈ 1959.2 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	541.35 GB	No	14.4 est.
Q4	8K default	545.45 GB	No	14.2 est.
Q4	32K	570.05 GB	No	—
FP16	4K	1955.1 GB	No	—
FP16	8K default	1959.2 GB	No	—
FP16	32K	1983.8 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).
