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

TL;DR

Run Gemma 2 9B Instruct on an Apple M3 Max with Ollama, using the Q8_0 quantization. Expect Grade S performance at ~225 tok/sec.

Prerequisites

Before starting, ensure you have at least 100GB of free disk space, macOS 13.0 or later, and Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install` in the terminal.

Expected performance

With the Q8_0 quantization, you can expect Gemma 2 9B Instruct to run at approximately 225 tok/sec, using 9.7GB of VRAM. Given the remaining 118.3GB of VRAM, you can maintain a practical context window of up to 8192 tokens, allowing for extensive and context-rich interactions.

1. Install runtimeOllama (preferred on Apple Silicon)

brew install ollama
ollama setup

2. Download the model

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

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 M3 Max

For optimal performance on the Apple M3 Max with 128GB of VRAM, use the Metal/MLX backend to leverage the GPU's MPS layers and unified memory. The Q8_0 quantization will use 9.7GB of VRAM, leaving 118.3GB available for context and other tasks. Ensure you have the latest macOS and Metal drivers installed.

Troubleshooting

Low token generation speed

Ensure you are using the Metal/MLX backend and the latest macOS version. Run `ollama setup` to verify the configuration.

Out of memory errors

Reduce the context length to 4096 or lower. Adjust the batch size if you are using custom configurations.

Model not found

Re-run the `ollama pull` command to ensure the model is downloaded correctly. Check your internet connection and try again.

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. Choose an alternative if you need specific features or encounter issues with Ollama.
