To use Mistral on-device, you can follow these steps as outlined in the WWDC sessions:

  1. Model Training and Preparation:

    • Define and Train the Model: Start by defining the model architecture and training it using libraries like PyTorch or TensorFlow. Utilize Apple silicon and the unified memory architecture on Mac for high-performance training.
    • Convert to Core ML Format: Convert the trained model into Core ML format using Core ML tools. This step includes optimizing the model representation and parameters to achieve great performance while maintaining accuracy.
  2. Model Integration:

    • Integrate with Apple Frameworks: Use Core ML to integrate the model into your app. Core ML provides a unified API for performing on-device inference across various machine learning and AI model types. It optimizes hardware-accelerated execution across the CPU, GPU, and neural engine.
  3. Optimization Techniques:

    • Quantization and KV Cache: Apply techniques like quantization and efficient key-value caching to optimize the model further. For example, the Mistral 7B model can be converted to a Core ML model with post-training per-block quantization to run smoothly on Apple silicon.
  4. Running the Model:

    • Execution on Device: Once integrated, you can run the model on your device. Core ML optimizes the execution, ensuring efficient performance.
