  • Python-first design
  • Unified memory architecture

Why Apple Silicon?

  • Billions of devices
  • High-performance GPU
  • Shared memory model
  • Massive untapped potential

Core Design Principles

  • Simple and intuitive API
  • Familiar NumPy-like syntax
  • Lazy evaluation
  • Composable functions

Architecture Overview

  • NumPy-like array interface
  • Unified memory (CPU + GPU)
  • Automatic differentiation

Key Features

  • Efficient inference on-device
  • Fine-tuning and training
  • Memory-optimized operations
  • Cross-platform compatibility

MLX vs Alternatives

  • PyTorch: GPU-focused, larger overhead
  • TensorFlow: Production-heavy, complex
  • JAX: Functional, steep learning curve
  • MLX: Apple Silicon native, lightweight

Core Concepts

  • Arrays: Lazy computation model
  • Operations: GPU-accelerated when beneficial
  • Gradients: Full autodiff support
  • Training: Lightning-fast fine-tuning

Training Pipeline: Data to Inference

Step 1: Data Preparation

  • Extract and annotate domain-specific patterns
  • Convert to optimized training tensors

Step 2: Model Training

  • Train specialized architectures from scratch
  • Metal-accelerated on Apple Silicon

Step 3: Deploy & Inference

  • Package models (.npz or .safetensors)
  • Load at startup, run in parallel

What You Can Do

  • Train specialized models from scratch
  • Inference on M-series chips in <50ms
  • Parallel model execution
  • Bundle models directly in apps

The Future

  • On-device AI becomes standard
  • Privacy-first applications
  • Distributed ML at the edge
