What is Generative AI?

Last updated · 1 min read

The family tree in one minute

AI — machines doing useful tasks → Machine learning — tasks learned from data instead of programmed rules → Deep learning — learning with large neural networks → Generative AI — networks large enough to create text, images, audio, video and code.

The LLM behind ChatGPT is generative AI for text. Midjourney is generative AI for images. Same principle — predict what a plausible continuation looks like — applied to different materials.

Where you already use it (maybe without knowing)

  • Autocomplete and "smart replies" in email
  • Photo enhancement on your phone (generative fill)
  • The chatbot you tried last month
  • Code completion like Copilot
  • The summary at the top of a search result

The two things to hold onto

  1. It generates, it does not verify. Plausible output is the product — hallucination is a feature of how it works, not a bug someone forgot to fix.
  2. It is a collaborator, not an oracle. The people getting the most out of it treat it like a fast first-draft partner with infinite patience — and keep the judgment for themselves.

Frequently asked questions

Is ChatGPT generative AI?
Yes — ChatGPT generates new text in response to your prompts, which is the definition of generative AI. The image, music and video tools work the same way in their own medium.
What is the difference between AI and generative AI?
AI is the umbrella term for machines doing useful tasks. Generative AI is the subset that creates new content. Your email spam filter is AI but not generative; ChatGPT is both.
Why did generative AI explode in 2022 and not earlier?
Three curves crossed — vastly more data, vastly more computing power, and a simple interface (chat) on top of models that had quietly been improving for a decade. ChatGPT made it visible overnight.
