In shortHigh-risk AI is the EU AI Act's most heavily regulated category: systems that can significantly affect people's safety or fundamental rights, such as AI used in recruitment, credit, education and critical infrastructure. Providers and deployers face the strictest duties. Most high-risk obligations fall due across 2027 and 2028, with the amended dates confirmed by Regulation (EU) 2026/1744.

What makes an AI system high-risk?

There are two routes. A system is high-risk if it is listed as an Annex III use-case — areas such as recruitment, creditworthiness, education, essential services, law enforcement and critical infrastructure — or if it is a safety component of, or itself, a product already regulated under Annex I (such as medical devices or machinery). A narrow exception applies where an Annex III system does not pose a significant risk. See what is high-risk AI?

Obligations for providers of high-risk AI

Providers carry the heaviest load: a continuous risk-management system, data governance, detailed technical documentation, record-keeping and logging, transparency to deployers, human-oversight design, and appropriate accuracy, robustness and cybersecurity. Before placing the system on the market they must complete a conformity assessment and register it.

Obligations for deployers of high-risk AI

Deployers must use the system in line with its instructions, ensure competent human oversight, monitor its operation, keep logs, and inform people where required. Certain deployers — including public bodies and some others — must also carry out a Fundamental Rights Impact Assessment before use.

When do high-risk rules apply?

Regulation (EU) 2026/1744 confirmed the amended dates: 2 December 2027 for Annex III systems and 2 August 2028 for Annex I product-embedded systems. See the EU AI Act timeline.

How to prepare for high-risk obligations

Find your high-risk systems first: build an AI inventory and classify each system. For anything high-risk, stand up the risk-management, documentation and oversight controls now — the deferred dates buy time, not a reprieve. You can check your exposure to see where you stand.

Frequently asked questions

What is high-risk AI under the EU AI Act?

AI that can significantly affect people's safety or fundamental rights — for example systems used in recruitment, credit, education or critical infrastructure.

How is an AI system classified as high-risk?

Either it is an Annex III use-case, or it is a safety component of (or is) a product regulated under Annex I, unless a narrow no-significant-risk exception applies.

What obligations apply to high-risk AI?

Risk management, data governance, documentation, logging, transparency, human oversight and accuracy — plus conformity assessment for providers.

When do high-risk AI rules apply?

2 December 2027 for Annex III systems and 2 August 2028 for Annex I product-embedded AI, as confirmed by Regulation (EU) 2026/1744.

What's the first step for high-risk AI?

Build an AI inventory and classify each system — you cannot meet high-risk obligations for systems you have not identified.
