Frequently Asked Questions
How much VRAM does MiMo V2.6 Flash RL UNCENSORED need?
MiMo V2.6 Flash RL UNCENSORED requires 96.0 GB of VRAM at Q4_K_M, or 319.1 GB at BF16. Full 1049K context adds up to 51.4 GB (147.4 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 159.4B × 4.8 bits ÷ 8 = 95.6 GB
KV Cache + Overhead ≈ 0.4 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 ≈ 51.9 GB (at full 1049K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run MiMo V2.6 Flash RL UNCENSORED?
No — MiMo V2.6 Flash RL UNCENSORED requires at least 68.1 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 Flash RL UNCENSORED?
For MiMo V2.6 Flash RL UNCENSORED, Q4_K_M (96.0 GB) offers the best balance of quality and VRAM usage. Q5_K_M (113.9 GB) provides better quality if you have the VRAM. The smallest option is Q2_K at 68.1 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run MiMo V2.6 Flash RL UNCENSORED on a Mac?
Yes — Mac Studio (M3 Ultra, 96GB) and 20 other Macs can run MiMo V2.6 Flash RL UNCENSORED, the smallest at Q3_K_M. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 96.0 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (128 GB).
Can I run MiMo V2.6 Flash RL UNCENSORED locally?
Yes — MiMo V2.6 Flash RL UNCENSORED can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is MiMo V2.6 Flash RL UNCENSORED?
At Q4_K_M, MiMo V2.6 Flash RL UNCENSORED can reach ~50 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.
tok/s = (bandwidth GB/s ÷ model GB) × efficiency
Example: NVIDIA B200 → 8000 ÷ 96.0 × 0.65 = ~54 tok/s
Estimated speed at Q4_K_M (96.0 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of MiMo V2.6 Flash RL UNCENSORED?
At Q4_K_M, the download is about 95.62 GB. The full-precision BF16 version is 318.72 GB. The smallest option (Q2_K) is 67.73 GB.
Which GPUs can run MiMo V2.6 Flash RL UNCENSORED?
No single consumer GPU has enough VRAM to run MiMo V2.6 Flash RL UNCENSORED at Q4_K_M (96.0 GB). Multi-GPU or professional hardware is required.
Which devices can run MiMo V2.6 Flash RL UNCENSORED?
18 devices with unified memory can run MiMo V2.6 Flash RL UNCENSORED at Q4_K_M (96.0 GB), including ASUS Ascent GX10, Mac Pro M2 Ultra (128 GB), Mac Pro M2 Ultra (192 GB), Mac Studio (M3 Ultra, 256GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
