Hard ideas. Easy words.

We take out the hard part, not the big idea. You get it the first time.

The textbookA large language model generates text autoregressively, sampling each token from a probability distribution conditioned on the preceding context window.

Stories

Every unit is a story about real-life people.

Elena's phone shows how ChatGPT writes. Sam's cake stall shows how to set a price. You remember people, so you remember the idea.

Elena's phone guesses

Elena texts "See you". Her phone suggests "soon". ChatGPT guesses its next word the same way.

Femi sees a shocking headline and shares it. Ada first checks who wrote it. That is called checking the source.

Sam’s stall fee

Sam rents a market stall. If each cake only covers flour and lemons, Sam loses money. Each cake must also pay a fixed share of the rent.
