Frequently Asked Questions
How much VRAM does MiMo V2.6 Pro RL UNCENSORED need?
MiMo V2.6 Pro RL UNCENSORED requires 615.0 GB of VRAM at Q4_K_M, or 2048.9 GB at BF16. Full 1049K context adds up to 112.5 GB (727.6 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 1024.2B × 4.8 bits ÷ 8 = 614.5 GB
KV Cache + Overhead ≈ 0.5 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 ≈ 113.1 GB (at full 1049K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run MiMo V2.6 Pro RL UNCENSORED?
No — MiMo V2.6 Pro RL UNCENSORED requires at least 435.8 GB at Q2_K, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for MiMo V2.6 Pro RL UNCENSORED?
For MiMo V2.6 Pro RL UNCENSORED, Q4_K_M (615.0 GB) offers the best balance of quality and VRAM usage. Q5_K_M (730.3 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 435.8 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run MiMo V2.6 Pro RL UNCENSORED on a Mac?
Yes, but only at lower quantizations. The smallest Mac that can run MiMo V2.6 Pro RL UNCENSORED is Mac Studio (M3 Ultra, 512GB) at Q3_K_M; 1 of the 146 Macs we list can run it at some quantization. For Q4_K_M (615.0 GB) you need a Mac with more unified memory.
