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.
