Frequently Asked Questions

How much VRAM does MiMo V2.5 need?

MiMo V2.5 requires 186.8 GB of VRAM at Q4_K_M, or 621.9 GB at BF16. Full 1049K context adds up to 51.4 GB (238.3 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 310.8B × 4.8 bits ÷ 8 = 186.5 GB

KV Cache + Overhead ≈ 0.3 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.

KV Cache + Overhead ≈ 51.8 GB (at full 1049K context)

Can NVIDIA GeForce RTX 5090 run MiMo V2.5?

No — MiMo V2.5 requires at least 85.9 GB at IQ2_XXS, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.

What's the best quantization for MiMo V2.5?

For MiMo V2.5, Q4_K_M (186.8 GB) offers the best balance of quality and VRAM usage. Q4_K_L (190.7 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 85.9 GB.

Can I run MiMo V2.5 on a Mac?

Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run MiMo V2.5, the smallest at IQ2_XXS. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 186.8 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (192 GB).

Can I run MiMo V2.5 locally?

Yes — MiMo V2.5 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is MiMo V2.5?

At Q4_K_M, MiMo V2.5 can reach ~85 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)

Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.

Example: NVIDIA B200 → 10.5 GB active ÷ (8000 × 0.65) = 2.01 ms, plus 48 layers × 0.055 ms = 2.64 ms, so 1000 ÷ 4.65 ms = ~215 tok/s

Estimated speed at Q4_K_M (186.8 GB)

~215 tok/s
~215 tok/s
~85 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.

What's the download size of MiMo V2.5?

At Q4_K_M, the download is about 186.45 GB. The full-precision BF16 version is 621.51 GB. The smallest option (IQ2_XXS) is 85.46 GB.

Which GPUs can run MiMo V2.5?

No single consumer GPU has enough VRAM to run MiMo V2.5 at Q4_K_M (186.8 GB). Multi-GPU or professional hardware is required.

Which devices can run MiMo V2.5?

4 devices with unified memory can run MiMo V2.5 at Q4_K_M (186.8 GB), including Mac Pro M2 Ultra (192 GB), Mac Studio (M3 Ultra, 256GB), Mac Studio (M3 Ultra, 512GB), Mac Studio M2 Ultra (192 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
