Frequently Asked Questions
- How much VRAM does MiniMax M3 Uncensored need?
MiniMax M3 Uncensored requires 256.7 GB of VRAM at Q4_K_M, or 854.6 GB at BF16. Full 1049K context adds up to 96.5 GB (353.2 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 427.0B × 4.8 bits ÷ 8 = 256.2 GB
KV Cache + Overhead ≈ 0.5 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 97 GB (at full 1049K context)

- Can I run MiniMax M3 Uncensored on a Mac?
MiniMax M3 Uncensored requires at least 182.0 GB at Q2_K, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.
- Can I run MiniMax M3 Uncensored locally?
Yes — MiniMax M3 Uncensored can run locally on consumer hardware. At Q4_K_M quantization it needs 256.7 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is MiniMax M3 Uncensored?
At Q4_K_M, MiniMax M3 Uncensored can reach ~17 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 B300 → 8000 ÷ 256.7 × 0.65 = ~20 tok/s
Estimated speed at Q4_K_M (256.7 GB)
~20 tok/s~17 tok/s~17 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
