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)

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 ≈ 26.3 GB (at full 205K context)

Can I run MiniMax M2.7 BF16 on a Mac?

Yes — Mac Pro M2 Ultra (128 GB) and 14 other Macs can run MiniMax M2.7 BF16, 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 137.8 GB of usable unified memory (RAM minus macOS overhead), from Mac Pro M2 Ultra (192 GB).

Can I run MiniMax M2.7 BF16 locally?

Yes — MiniMax M2.7 BF16 can run locally on consumer hardware. 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 ~73 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 → 6.6 GB active ÷ (8000 × 0.65) = 1.28 ms, plus 62 layers × 0.055 ms = 3.41 ms, so 1000 ÷ 4.69 ms = ~213 tok/s

Estimated speed at Q4_K_M (137.8 GB)

~213 tok/s
~213 tok/s
~182 tok/s

Real-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?

No single consumer GPU has enough VRAM to run MiniMax M2.7 BF16 at Q4_K_M (137.8 GB). Multi-GPU or professional hardware is required.

Which devices can run MiniMax M2.7 BF16?

4 devices with unified memory can run MiniMax M2.7 BF16 at Q4_K_M (137.8 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.
