Transformer Models with PyTorch Cheatsheet

A transformer is a stack of understandable parts: token embeddings, positional encoding, masked multi-head attention, feed-forward sublayers, and residual-normalised blocks. This cheatsheet gathers every component on one page, from the attention formula to the built-in nn.Transformer, each snippet annotated line by line. Keep it open while you build, or save the image and pin it nearby.

For the full background, read the guide to transformer models with PyTorch. To practise, work through the 10 code-along examples.
