Can H200 141GB SXM5 run Mistral-Small-4-119B-2603?

NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth · Mistral · 119.0B (active 6.5B) · MoE · model ctx up to 256K

Yes — the H200 141GB SXM5 (141 GB HBM3e) can run Mistral-Small-4-119B-2603. At Q4 with the default 8K context it needs ≈ 67.75 GB VRAM (weights 65.45 GB + KV cache 1.3 GB + 1 GB runtime overhead), which fits within 141 GB. Decode at Q4/8K: ≈ 469.9 tok/s (estimated, batch 1). FP16 needs ≈ 240.3 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).
