What is generative AI? Watch
Generative AI is AI that creates new content: text, images, audio, video or code. You describe what you want in plain words, called a prompt, and it generates it.
Older AI mostly predicts or sorts: is this email spam? Which product will you like? Generative AI makes something new: write the email, design the poster.
How it works Watch
- It is trained on millions of examples - text, pictures, sounds - and learns their patterns.
- You give a prompt, like "a poster for my bakery, warm colours".
- It generates new content that fits those patterns. It does not copy-paste one example.
- Then you check it for facts, quality and rights before you use it.
Text and images: two different tricks Watch
- Text comes from a large language model that predicts the next word again and again.
- Images often come from a diffusion model: it starts with random noise, like TV static, and removes it step by step until a picture matching your words appears.

- Hallucination: generated text can contain made-up facts. Check before you share.

- Copyright: do not copy famous characters, logos or an artist's exact work.
- Privacy: never upload private documents or other people's photos without permission.

Frequently asked questions
What is the difference between AI and generative AI?
AI is the whole field. Generative AI is the part of AI that creates new content, like text or images, instead of only predicting or sorting.
Is ChatGPT generative AI?
Yes. ChatGPT generates text (and images and voice) from your prompts, using large language models.
Is generative AI free?
Many tools, like ChatGPT, Gemini and Copilot, have free plans with limits. Paid plans add more use and better models.
