AI that interprets images and video — reading a document, recognising a product, counting people. The part of AI that has been quietly working in industry for years.
Prompt Injection
An attack where hidden instructions in a web page or document trick an AI into ignoring its real orders. The reason a careful assistant treats page content as information, never as commands.

Guardrails
The limits placed on what an AI may say or do — refusing certain requests, staying on topic, never inventing a price. Essential on anything customer-facing.
Training Data
