Setup tutorial: Llama 3.2 3B Instruct on M4 Pro

AI-generated, GPU-specific. Verified commands for your exact hardware.

TL;DR

Llama 3.2 3B Instruct runs at Grade S (~274 tok/sec) on Apple M4 Pro using the Q8_0 quantization. Requires 3.7GB VRAM, leaving ample headroom for large contexts.

Prerequisites

Before starting, ensure you have at least 10GB 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 Q8_0 quantization, you can expect the model to run at approximately 274 tokens per second, utilizing 3.7GB of VRAM. Given the 48GB VRAM of the Apple M4 Pro, you will have 44.3GB of headroom for context, allowing for very large context windows without running into memory constraints.

1. Install runtimeOllama (preferred on Apple Silicon)

brew install ollama
ollama setup

2. Download the model

Download the Q8_0 quantized model (3.2GB file) from Hugging Face.

ollama pull bartowski/Llama-3.2-3B-Instruct-GGUF:Llama-3.2-3B-Instruct-Q8_0.gguf

3. Run it

ollama run Llama-3.2-3B-Instruct-Q8_0.gguf
ollama chat

4. Optimize for M4 Pro

For optimal performance on the Apple M4 Pro, leverage the Metal/MLX backend to utilize the 48GB of unified memory. Ensure that MPS layers are enabled to take advantage of the GPU's parallel processing capabilities. The Q8_0 quantization is well-suited for this setup, balancing model accuracy and resource efficiency.

Troubleshooting

If you encounter an 'out of memory' error, try reducing the batch size or context length.

ollama config set batch_size 16

If the model runs slowly, ensure that the Metal/MLX backend is properly configured.

ollama config set backend metal

If you see an 'MPS layer not found' error, reinstall the Ollama runtime.

brew reinstall ollama && ollama setup

Alternative runtimes

While Ollama is the preferred runtime for Apple Silicon, you can also consider LM Studio for a more graphical interface, llama.cpp for fine-grained control over quantization, or MLX for direct Metal integration. Jan is another option if you need a lightweight solution. Choose based on your specific needs for performance, ease of use, and customization.
