Can I Run MiniMax M3 on NVIDIA H100 80GB (PCIe)?
Written by Jakub Rusinowski · Last updated July 21, 2026
No — MiniMax M3-VL at Q4_K_M needs 143.2 GB at 8K context (138.9 GB weights + 4.3 GB KV cache/overhead), and the NVIDIA H100 80GB (PCIe)'s 80 GB leaves it ~63.2 GB short. The cheapest card that runs it is the Apple M2 Ultra (192 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 143.2 GB ✗ · 32K 153.8 GB ✗ · 128K 196 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.
No compatible GPU? MiniMax M3-VL on 128 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every MiniMax M3 variant requires more VRAM than the NVIDIA H100 80GB (PCIe) provides (80 GB).
