High-level summary of the AI Act

The EU AI Act classifies AI systems by risk level, from prohibited (like social scoring systems that manipulate behavior) to minimal risk (unregulated). High-risk AI systems, such as those used in critical decisions affecting people's lives, face strict regulations requiring developers to provide documentation, conduct testing, and monitor for problems. General-purpose AI (large language models that can do many tasks) have lighter requirements unless they present systemic risk, in which case developers must test them against adversarial attacks (attempts to trick or break them) and report serious incidents.
