TL;DR

Run Gemma 2 9B Instruct on an Apple M4 Max with a Grade S performance, using the Q8_0 quantization for ~225 tok/sec speed.

Prerequisites

Before starting, ensure you have at least 10GB 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` in your terminal.

Expected performance

With the Q8_0 quantization, you can expect the model to run at approximately 225 tokens per second, using around 9.7GB of VRAM. Given the 128GB VRAM, you will have 118.3GB of headroom for context, allowing for a practical context window of up to 8192 tokens without significant performance degradation.

1. Install runtimeOllama (preferred on Apple Silicon)

brew install ollama
ollama init

2. Download the model

Download the Q8_0 quantized version of Gemma 2 9B Instruct (9.2GB file size) from Hugging Face.

ollama pull bartowski/gemma-2-9b-it-GGUF:q8_0

3. Run it

ollama run bartowski/gemma-2-9b-it-GGUF:q8_0
ollama chat bartowski/gemma-2-9b-it-GGUF:q8_0

4. Optimize for M4 Max

For optimal performance on the Apple M4 Max, utilize the Metal/MLX backend to leverage the 128GB of unified memory. Ensure that MPS layers are enabled to take full advantage of the GPU's capabilities. The Q8_0 quantization is specifically tuned for this hardware, balancing performance and memory usage.

Troubleshooting

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

ollama config set max_context_length 4096

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

ollama config set backend metal

If you see errors related to MPS layers, check that they are enabled.

ollama config set use_mps true

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 more control over quantization, and MLX for direct Metal integration. Jan is another option but may require additional setup for Apple M4 Max.
