What is generative AI?

SHORT ANSWER

Generative AI creates things such as text, images, audio or code from an instruction. It can produce a useful draft, and you still need to decide whether the output is accurate and fits the task.

How an instruction becomes an answer

A language model has been trained to recognise patterns in large amounts of text. When you ask a question, it uses your instruction and the surrounding context to build an answer step by step. An AI service may also have tools for retrieving web pages or reading documents. Which evidence it actually used depends on the service and task.

A workplace scenario

You have a 500-word public course description and need a short email. Ask for 100 words aimed at people new to the subject, using the description as the source. Check the course name, what is included and the link before sending. Notice which sentences became clearer and which details you had to restore.

Choose a task with an answer you can check

Start with something you already know how to judge, such as shortening a text or organising ideas. Keep the original and compare. This builds both your ability to give a clear instruction and your judgement of what actually improved.
