Can H200 141GB SXM5 run GLM-5.1?

NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth · Z.ai · 753.9B (active 40B) · MoE · model ctx up to 198K

No — GLM-5.1 at Q4 needs ≈ 419.65 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: ≈ 24.2 tok/s (estimated, batch 1). FP16 needs ≈ 1516.8 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.

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).
