TL;DR

Run Mistral Nemo Base 12B on an Apple M4 Max with BF16 quantization for Grade S performance at ~83 tokens/second.

Prerequisites

Before starting, ensure you have at least 50GB of free disk space, macOS Ventura 13.0 or later, and Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install` in your terminal.

Expected performance

With the BF16 quantization, you can expect the model to run at approximately 83 tokens/second, using around 24.5GB of VRAM. This leaves you with 103.5GB of VRAM for context, allowing for a practical context window of up to 131,072 tokens, depending on the complexity of the input.

1. Install runtimeOllama (preferred on Apple Silicon)

brew install ollama
ollama setup

2. Download the model

Download the BF16 quantized version of the Mistral Nemo Base 12B model (24.0GB file size) from Hugging Face.

ollama pull mistralai/Mistral-Nemo-Base-2407

3. Run it

ollama run mistralai/Mistral-Nemo-Base-2407

4. Optimize for M4 Max

To optimize performance on the Apple M4 Max, use the Metal/MLX backend for efficient GPU utilization. The 128GB VRAM allows for significant headroom, enabling you to maintain high performance while handling large context windows. Ensure that MPS layers are enabled to leverage the unified memory architecture effectively.

Troubleshooting

Model fails to load due to insufficient VRAM

Ensure you have at least 128GB of VRAM available. If not, consider using a lower quantization like Q4_K_M.

Performance is significantly slower than expected

Check that the Metal/MLX backend is enabled and that MPS layers are utilized. Run `ollama config --backend metal` to set the backend.

Model crashes during inference

Increase the swap space or reduce the batch size. Run `ollama config --swap-size 100G` to allocate more swap space.

Alternative runtimes

For users who prefer different runtimes, consider LM Studio for a GUI-based interface, llama.cpp for more control over quantization, MLX for direct Metal integration, or Jan for a lightweight alternative. Each has its own strengths, but Ollama is generally recommended for its ease of use and performance on Apple Silicon.
