Setup tutorial: Qwen 2.5 14B on M4 Pro
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Qwen 2.5 14B on an Apple M4 Pro with Grade S performance at ~49 tok/sec using the Q8_0 quantization. Requires 15.1GB VRAM and 14.6GB disk space.
Prerequisites
Before starting, ensure you have at least 50GB 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 the terminal.
Expected performance
With the Q8_0 quantization, you can expect ~49 tok/sec performance while using 15.1GB of VRAM. This leaves approximately 32.9GB of VRAM headroom for context, allowing for a practical context window of up to 131,072 tokens. This setup ensures snappy and efficient inference even with large contexts.
1. Install runtimeOllama (preferred on Apple Silicon)
brew install ollama
ollama init2. Download the model
Download the Qwen 2.5 14B Q8_0 quantized model (14.6GB file) from Hugging Face.
ollama pull bartowski/Qwen2.5-14B-Instruct-GGUF:Qwen2.5-14B-Instruct-Q8_0.gguf3. Run it
ollama run Qwen2.5-14B-Instruct-Q8_0.gguf
ollama chat --model Qwen2.5-14B-Instruct-Q8_0.gguf4. Optimize for M4 Pro
For optimal performance on the Apple M4 Pro, leverage the Metal/MLX backend and utilize the 48GB unified memory. Ensure that the MPS (Metal Performance Shaders) layers are enabled to take full advantage of the GPU. The Q8_0 quantization is specifically optimized for this setup, balancing memory usage and inference speed.
Troubleshooting
Inference is slow or hangs.
Ensure that the Metal/MLX backend is enabled and that the MPS layers are properly configured. You can check this by running `ollama config` and verifying the settings.
Out of memory errors during inference.
Reduce the context length to fit within the available VRAM. For example, try setting the context length to 65,536 tokens by running `ollama config --context-length 65536`.
Model fails to load.
Verify that the model file has been downloaded correctly and is not corrupted. You can redownload the model using the `ollama pull` command.
Alternative runtimes
Alternative runtimes include LM Studio, llama.cpp, and MLX. LM Studio provides a more user-friendly interface but may not be as performant as Ollama. llama.cpp is highly customizable and can be fine-tuned for specific use cases, but it requires more manual setup. MLX is another option for leveraging Metal on Apple Silicon, but Ollama is generally easier to set up and use for most users.
