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

TL;DR

Llama 3.2 1B Instruct runs at Grade S on the Apple M4 Pro with FP16 quantization, achieving ~423 tok/sec.

Prerequisites

Before starting, ensure you have at least 5GB of free disk space, macOS 12.3 or later, and Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install`.

Expected performance

With the FP16 quantization, you can expect the Llama 3.2 1B Instruct model to run at approximately 423 tokens per second, using around 2.8GB of VRAM. This leaves you with 45.2GB of VRAM headroom, 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 init

2. Download the model

Download the FP16 quantized model (2.3GB file) from Hugging Face.

ollama pull bartowski/Llama-3.2-1B-Instruct-GGUF:Llama-3.2-1B-Instruct-f16.gguf

3. Run it

ollama run Llama-3.2-1B-Instruct-f16.gguf
ollama chat --model Llama-3.2-1B-Instruct-f16.gguf

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. With 48GB of VRAM, you have ample headroom for large context windows and multiple concurrent tasks.

Troubleshooting

Model fails to load due to insufficient VRAM.

Ensure that the Metal/MLX backend is properly configured and that you are using the FP16 quantization. If issues persist, try reducing the context length.

Performance is lower than expected.

Check that the MPS layers are enabled and that the Metal/MLX backend is correctly set up. Restart the runtime if necessary.

Ollama commands are not recognized.

Ensure that Ollama is installed correctly by running `brew install ollama` and then `ollama init`. Add Ollama to your PATH if it is not already included.

Alternative runtimes

While Ollama is the preferred runtime for Apple Silicon, alternatives like LM Studio, llama.cpp, and MLX can also be used. LM Studio provides a graphical interface and is useful for users who prefer a visual setup. llama.cpp is more lightweight and suitable for systems with limited resources. MLX offers advanced features for researchers and developers. Choose based on your specific needs and system configuration.
