Generative AI
noun
AI that produces new text, images, audio, code or other material from patterns learned during training. It generates rather than merely retrieves, which is why it can be useful, original-looking and wrong at the same time.
Also known as GenAI
Generative AI is the branch of AI that makes things: text, images, audio, video, code and the first draft of the email you did not want to write. It learns patterns from large bodies of material and uses them to produce a new response to a prompt. New does not mean lived, witnessed or true. The system can generate a convincing answer with no experience behind it, and produce a false detail with the same composure as a correct one. That is not a technical footnote; it is the reason the output still needs a person. In the book, generative AI is less a mechanical colleague than an acceleration engine: it removes blank pages, moves information between forms and makes competent output cheap. The human job begins where the generation ends, deciding whether the thing is right, useful, safe and worth sending.
