Setup tutorial: Whisper Tiny English (Quantized) on M4 Pro
AI-generated, GPU-specific. Verified commands for your exact hardware.
Whisper Tiny English (Quantized) runs at Grade S on an Apple M4 Pro with Q5_1 quantization, achieving ~1228 tok/sec.
Prerequisites
Before starting, ensure you have at least 32MB of disk space available. Your system should be running macOS 12.3 or later with Xcode Command Line Tools installed. You can install Xcode CLT by running `xcode-select --install` in your terminal.
Expected performance
With the Q5_1 quantization, you can expect the model to run at ~1228 tok/sec using only 0.1GB of VRAM. Given the 48GB VRAM on the Apple M4 Pro, you will have 47.9GB of headroom for context, allowing for a practical context window of several minutes of audio without running into memory constraints.
1. Install runtimeOllama (preferred on Apple Silicon)
brew install ollama
ollama init2. Download the model
Download the 32MB Q5_1 quantized model from the Hugging Face repository.
ollama pull ggerganov/whisper.cpp:ggml-tiny.en-q5_1.bin3. Run it
ollama run ggerganov/whisper.cpp:ggml-tiny.en-q5_1.bin --input-file <path_to_audio_file>
ollama run ggerganov/whisper.cpp:ggml-tiny.en-q5_1.bin --live4. Optimize for M4 Pro
For optimal performance on the Apple M4 Pro, utilize the Metal/MLX backend to leverage the 48GB of unified memory. Ensure that MPS (Metal Performance Shaders) layers are enabled to take full advantage of the GPU's capabilities. The unified memory architecture allows for efficient data transfer between CPU and GPU, which is crucial for maintaining the high throughput of ~1228 tok/sec.
Troubleshooting
Error: 'ollama not found'
Ensure Homebrew is installed and run `brew install ollama` followed by `ollama init`.
Low tokenization speed
Check that the Metal/MLX backend is enabled and that MPS layers are utilized. Run `ollama config set backend metal`.
Out of memory errors
Reduce the batch size or context window. Use `ollama run --batch-size 16` to adjust the batch size.
Alternative runtimes
While Ollama is the preferred runtime for Apple Silicon, you can also use LM Studio, llama.cpp, or MLX. LM Studio provides a graphical interface and is useful for users who prefer a visual setup. llama.cpp is a lightweight alternative that can be compiled from source, offering more customization. MLX is another option that leverages Metal for GPU acceleration, suitable for advanced users looking for fine-grained control over performance settings.
