Definition

A model architecture loosely inspired by neurons in the brain — in practice, a stack of matrix multiplications with non-linear functions between them. Deep learning is what you get when you stack many layers of these and train them on a lot of data.

  • From models to LLMs

    An LLM is one kind of ML model, trained on text, predicts the next token. That single trick at scale gets you ChatGPT, and also explains where it breaks.

  • What makes a model: data and algorithm

    A model is a file of learned numbers, produced by running an algorithm over data. Both ingredients matter, but bad data beats a good algorithm every time.

  • Inside AI: machine learning and deep learning

    Open the AI umbrella. Machine learning is the part that learns from data. Deep learning is ML done with neural networks, and that's where today's models live.
