KV cache by context
unresolved
This model declares a 128-token sliding window, but we could not establish which layers use it. Its architecture publishes the layout as a per-layer array inside the model file rather than as a period in config.json, and we have not yet ingested that array.
A flat context × layers × heads figure would be substantially too high, so we are not showing one. This is tracked as a known gap rather than filled with a guess.

Why other calculators give a different number
A parameters × bits ÷ 8 estimate puts Q4_K_M at roughly 536.05 GiB. The real file is 580.09 GiB, because a quantization is a mixture and some tensors are always kept at higher precision.

Questions people ask
- How much VRAM does MiMo-V2.5-Pro need?
- Q4_K_M is exactly 622,865,272,992 bytes (580.09 GiB) in weights. Add the KV cache, which depends on your context length, plus roughly half a gigabyte of runtime overhead.
- Is MiMo-V2.5-Pro a mixture-of-experts model?
- Yes — 384 experts, 8 routed per token. Every expert must be resident, but only the routed ones are read per token, which is why its memory requirement and its speed behave very differently.
- Which quantization of MiMo-V2.5-Pro should I use?
- Q4_K_M is the usual default. Pick the largest quantization that fits your card at the context you actually need — the table above gives exact sizes for every one published.
