How AI Actually Works (Under the Hood)

Now that you've used AI, peek under the hood. This intermediate module covers the three concepts most beginners skip: what machine learning actually is, the anatomy of a neural network, and how deep learning powers everything from ChatGPT to image generators. We'll also cover training data and gradient descent in plain English, why GPUs are the workhorses of modern AI, and the common failure modes — overfitting, bias, and hallucinations — so you understand why AI behaves the way it does.
