What it is
Generative AI is AI that produces new content instead of only sorting or predicting. It learns patterns from large amounts of existing text, images or sound and uses them to create something new on request.
What it can create
| Output | Typical technique | Business example |
|---|---|---|
| Text | Large language model | Drafting offers, summaries, answers |
| Images | Diffusion model1 | Product visuals, variations of a design |
| Audio and voice | Speech models | Phone assistants, voice-overs |
| Video | Video diffusion models | Short clips, explainers |
| Code | Large language model | Writing and checking software |
Where it saves work
Most of the value appears in customer operations, marketing and sales, software engineering and research and development, according to an estimate by McKinsey that puts the potential at 2.6 to 4.4 trillion US dollars a year worldwide.2 Such figures are estimates of potential, not measured results.
What needs checking
- Accuracy. Generated text can contain errors stated with confidence.
- Rights. Who owns the output, and was protected material used?
- Labelling. From August 2026 AI-generated or manipulated content must be marked as such in the EU.3
- Data. Confidential information should not go into public tools without a rule.
Key terms
- Diffusion model
- Creates images by turning random noise step by step into a picture.1
- Prompt
- The description or instruction you give the tool.
- Deepfake
- Realistic generated image, sound or video of real people or events.
