Frequently Asked Questions
- How much VRAM does MiniMax M2.7 BF16 need?
MiniMax M2.7 BF16 requires 137.8 GB of VRAM at Q4_K_M, or 457.9 GB at BF16. Full 205K context adds up to 25.8 GB (163.5 GB total).
VRAM = Weights + KV Cache + Overhead
Weights = 228.7B × 4.8 bits ÷ 8 = 137.2 GB
KV Cache + Overhead ≈ 0.6 GB (at 2K context + ~0.3 GB framework)
KV Cache + Overhead ≈ 26.3 GB (at full 205K context)

- Can I run MiniMax M2.7 BF16 on a Mac?
MiniMax M2.7 BF16 requires at least 97.8 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 M2.7 BF16 locally?
Yes — MiniMax M2.7 BF16 can run locally on consumer hardware. At Q4_K_M quantization it needs 137.8 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.
- How fast is MiniMax M2.7 BF16?
At Q4_K_M, MiniMax M2.7 BF16 can reach ~32 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 ÷ 137.8 × 0.65 = ~38 tok/s
Estimated speed at Q4_K_M (137.8 GB)
~38 tok/s~38 tok/s~32 tok/sReal-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
- What's the download size of MiniMax M2.7 BF16?
At Q4_K_M, the download is about 137.21 GB. The full-precision BF16 version is 457.38 GB. The smallest option (Q2_K) is 97.19 GB.
- Which GPUs can run MiniMax M2.7 BF16?
