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

TL;DR

Llama 3.2 3B Instruct runs at Grade S on the Apple M3 Max with Q8_0 quantization, achieving ~730 tok/sec.

Prerequisites

Before starting, ensure you have at least 5GB of free disk space, macOS 12 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 ~730 tok/sec, utilizing 3.7GB of VRAM. Given the 128GB of total VRAM, this leaves approximately 124.3GB available for context, allowing for a practical context window of up to 131072 tokens.

1. Install runtimeOllama (preferred on Apple Silicon)

brew install ollama
ollama init

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
ollama chat

4. Optimize for M3 Max

To optimize performance on the Apple M3 Max, ensure that you are using the Metal/MLX backend to leverage the 128GB of unified memory. The Q8_0 quantization is specifically tuned for this GPU, allowing efficient use of the 128GB VRAM while maintaining high throughput. Use the `OLLAMA_BACKEND=metal` environment variable to force the Metal backend.

Troubleshooting

Low token generation speed

Ensure the Metal/MLX backend is enabled by setting `OLLAMA_BACKEND=metal` before running the model.

Out of memory errors

Reduce the context length or batch size to fit within the available VRAM.

Model not found

Verify the model was successfully downloaded and is listed in `ollama models`. If not, re-run the `ollama pull` command.

Alternative runtimes

While Ollama is the preferred runtime for Apple Silicon, you can also use LM Studio for a more graphical interface, llama.cpp for fine-grained control, or MLX for direct Metal integration. Jan is another lightweight option but may not offer the same performance optimizations as Ollama on the Apple M3 Max.
