Can I Run MiMo-V2.5 on NVIDIA H100 80GB (PCIe)?
Written by Jakub Rusinowski · Last updated September 6, 2026
No — MiMo-V2.5 310B at Q4_K_M needs 191.9 GB at 8K context (187.2 GB weights + 4.7 GB KV cache/overhead), and the NVIDIA H100 80GB (PCIe)'s 80 GB leaves it ~111.9 GB short. The cheapest card that runs it is the Apple M5 Ultra (512 GB).

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 80 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA H100 80GB (PCIe): 8K 191.9 GB ✗ · 32K 203.5 GB ✗ · 128K 250.2 GB ✗. Past 8K it no longer fits 80 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
