Study chapter

AI

Models, data, and the thinking behind intelligent products.

The AI chapter builds a practical foundation in machine learning and applied AI, the same skills behind OZmind, our in-house AI engine.

What you'll learn

  • PyTorch, tensors, and how neural networks are trained
  • CNNs, residual connections, and how deep learning code is structured
  • Building a GPT-2 style Transformer from scratch
  • Mechanistic interpretability with TransformerLens and hooks
  • A hands-on interpretability project: steering, SAEs, IOI, and more
