Generative AI Basics

What Makes AI 'Generative'?

Classical AI classifies: is this email spam, is this tumour malignant? Generative AI creates: write this email, draw this picture, compose this melody. The shift from analysing to creating is what makes this generation of AI feel so different.

Key Concepts

  • Discriminative models assign labels; generative models produce new samples
  • Text, images, audio, video and code can all be generated today
  • Generative outputs are new combinations of learned patterns — not copies from a database
  • Quality has crossed a threshold: much generated content passes as human-made
  • The same capability that drafts your report can also fabricate misinformation — capability and risk are twins

Try It Yourself

Write down three tasks from your week and label each as classification (analysing) or generation (creating). Which could generative AI have accelerated?
