Quick answer
AI, or artificial intelligence, describes machine-based systems that use inputs to produce outputs such as predictions, recommendations, decisions, or generated content. Different AI systems use different methods and have different limits.
Original example
Sorting a crowded inbox
An email service can use a trained model to estimate whether each new message is spam. The output is a prediction, not certainty, so legitimate messages can still be classified incorrectly.
What AI systems do
AI systems process data according to designed or learned patterns. Some classify or forecast; generative systems create text, images, audio, or other content in response to prompts.
Performance depends on the task, data, design, and operating context. Human-sounding output does not prove understanding, accuracy, or neutrality.
Common misunderstandings
- AI is an umbrella term, not one single program or technique.
- Confident AI output can still be incomplete, biased, or wrong.
