Setup tutorial: Kokoro 82M TTS on M4 Pro
AI-generated, GPU-specific. Verified commands for your exact hardware.
Run Kokoro 82M TTS on an Apple M4 Pro with Grade S performance, using the ONNX-Q8F16 quantization. Expect ~1228 tok/sec and 0.6GB VRAM usage.
Prerequisites
Before starting, ensure you have at least 100MB 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 ONNX-Q8F16 quantization, you can expect ~1228 tok/sec and 0.6GB VRAM in use, leaving 47.4GB of VRAM for context. This allows for a practical context window of several minutes of audio, depending on the complexity of the input.
1. Install runtimeOllama (preferred on Apple Silicon)
brew install ollama
ollama init2. Download the model
Download the 86MB ONNX-Q8F16 quantized model from Hugging Face.
ollama pull onnx-community/Kokoro-82M-v1.0-ONNX:onnx/model_q8f16.onnx3. Run it
ollama run onnx-community/Kokoro-82M-v1.0-ONNX:onnx/model_q8f16.onnx
ollama chat --model onnx-community/Kokoro-82M-v1.0-ONNX:onnx/model_q8f16.onnx4. Optimize for M4 Pro
For optimal performance on the Apple M4 Pro, leverage the Metal/MLX backend to utilize the 48GB of unified memory. Ensure that MPS (Metal Performance Shaders) layers are enabled to take full advantage of the GPU's capabilities. The 48GB VRAM provides ample headroom for large contexts and batch processing.
Troubleshooting
Low token generation speed
Ensure 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 length. Adjust the model's configuration settings using `ollama config set batch_size 16`.
Model not loading
Verify that the model file has been downloaded correctly. Re-run the download command: `ollama pull onnx-community/Kokoro-82M-v1.0-ONNX:onnx/model_q8f16.onnx`.
Alternative runtimes
Alternative runtimes include LM Studio, llama.cpp, and MLX. LM Studio is suitable for GUI-based interaction, while llama.cpp offers more control over low-level optimizations. MLX is ideal for integrating the model into larger machine learning pipelines. Choose based on your specific use case and development environment.
