Does MiMo-V2.5-Pro fit in 32GB of VRAM?
Not at these settings. No indexed quantization of MiMo-V2.5-Pro fits 32GB card at any context we compute, with q4_0 KV. The smallest shipped quantization is 197.49 GiB in weights alone, against 29.76 GiB usable. CPU offload can still run it, slowly.

Figures are GiB of total memory: weights plus KV cache plus compute buffer and backend overhead. Weights and KV are near-exact; the overhead term is modeled. Hover any cell for the breakdown.
Why there are no speeds on this page
A capacity is not a card. Whether a model fits depends only on memory, so every figure above holds for any 32GB accelerator. How fast it runs depends on memory bandwidth, which varies several-fold between cards of the same capacity — so putting a tokens-per-second number here would be inventing one. Pick a specific card from hardware and the speed column appears.
Why other calculators disagree
A parameters × bits ÷ 8 estimate ignores two things that dominate at long context. First, the weights themselves are not the nominal rate — quantizations are mixtures, so the real file is consistently larger than the label implies. Second, most of this model's layers cache only a 128-token window rather than the full context.
