Question 1

Scope, roles, and staged application

Start every EU AI Act question with Article 2 scope and Article 3 roles. A company can be a provider for one AI system, a deployer for another, and a downstream provider when it integrates a general-purpose AI model into its own system.

The AI Act also has staged application dates. Chapters I and II apply from 2 February 2025, Chapter V GPAI duties and several governance and penalty provisions apply from 2 August 2025, the Regulation generally applies from 2 August 2026, and Article 6(1) with corresponding obligations applies from 2 August 2027.

Does the EU AI Act apply to a non-EU provider?

Yes, if the provider places an AI system or general-purpose AI model on the Union market, puts an AI system into service in the Union, or is established outside the Union but the AI system output is used in the Union. The answer should record the market, customer, output-use location, and operator role.

How do provider and deployer roles differ under the EU AI Act?

A provider is responsible for developing, placing on the market, or putting into service an AI system or GPAI model under its own name or trademark. A deployer is the organisation using an AI system under its authority. The same organisation may hold different roles for different systems or lifecycle steps.

Which EU AI Act dates should most teams track first?

Track 2 February 2025 for Chapters I and II, including prohibited practices and AI literacy; 2 August 2025 for GPAI obligations, notified-body and governance provisions, penalties, and Article 78; 2 August 2026 for general application; and 2 August 2027 for Article 6(1) high-risk product-safety classification and related obligations.

  • Article 2 covers providers placing AI systems or GPAI models on the Union market, EU deployers, certain third-country providers and deployers where the output is used in the Union, importers, distributors, product manufacturers, authorised representatives, and affected persons in the Union.
  • A provider develops, or has developed, an AI system or GPAI model and places it on the market or puts an AI system into service under its own name or trademark.
  • A deployer uses an AI system under its authority, except for personal non-professional use.
  • The AI Act excludes areas outside Union law and several military, defence, national security, and specified international cooperation uses.
Question 2

Prohibited practices and high-risk classification

Article 5 is the first stop for unacceptable-risk uses. It prohibits specific practices, including manipulative or exploitative systems causing or likely to cause significant harm, certain social scoring, certain criminal-risk prediction based solely on profiling or personality traits, untargeted scraping for facial recognition databases, workplace and education emotion recognition except for medical or safety reasons, certain sensitive biometric categorisation, and law-enforcement real-time remote biometric identification in publicly accessible spaces except within narrow conditions.

If Article 5 does not prohibit the use, the next question is whether Article 6 classifies it as high-risk. High-risk status can come from a covered product-safety route under Article 6(1), or from an Annex III use case under Article 6(2), subject to the Article 6(3) narrow non-high-risk derogation.

Is every AI system under the EU AI Act high-risk?

No. The AI Act uses a risk-based approach. Some practices are prohibited, some systems are high-risk, some systems have specific transparency obligations, GPAI models have their own rules, and many AI systems are outside high-risk classification unless a product-safety route or Annex III use case applies.

What makes an AI system high-risk under Article 6(1)?

Article 6(1) applies when the AI system is intended as a safety component of a product, or is itself a product, covered by listed Union harmonisation legislation and that product or system must undergo third-party conformity assessment before market placement or putting into service.

Can an Annex III AI system be treated as not high-risk?

Sometimes. Article 6(3) allows a derogation where the Annex III system does not pose a significant risk of harm to health, safety, or fundamental rights, including because it does not materially influence decision-making. The provider must document the assessment and register the non-high-risk conclusion. If the system profiles natural persons, it is always high-risk.

  • For Article 5, document the exact intended purpose, users, affected persons, data source, deployment context, and whether any exception or Member State authorisation route is being relied on.
  • For Article 6(1), check whether the AI system is a safety component of a product, or is itself a product, covered by listed Union harmonisation legislation and subject to third-party conformity assessment.
  • For Annex III, check biometrics, critical infrastructure, education, employment, essential services, law enforcement, migration and border control, and justice or democratic-process use cases.
  • If a provider concludes an Annex III system is not high-risk under Article 6(3), it must document that assessment before market placement or putting into service and register the system under Article 49(2).
Question 3

High-risk obligations, FRIA, registration, and incidents

For high-risk AI systems, the FAQ answer should separate provider obligations from deployer obligations. Providers carry the core pre-market compliance package: Section 2 requirements, quality management, technical documentation, logs where under their control, conformity assessment, EU declaration of conformity, CE marking, registration, corrective actions, and authority cooperation.

Deployers have operational duties once they use the system, including using instructions for use, assigning competent human oversight, monitoring operation, using relevant input data where under their control, keeping logs under their control for an appropriate period of at least six months unless another law says otherwise, informing affected workers before workplace use, and informing natural persons when Annex III high-risk systems make or assist decisions about them.

What records should a provider have for a high-risk AI system?

A provider should have the Article 16 compliance package: quality management, technical documentation, logs where under its control, conformity assessment records, EU declaration of conformity, CE marking evidence, Article 49 registration, corrective-action records, and materials needed to demonstrate conformity to competent authorities.

When is a fundamental rights impact assessment required under the EU AI Act?

A FRIA is required before first deployment for the deployers listed in Article 27 when they deploy covered Article 6(2) high-risk AI systems, except the Annex III critical-infrastructure area. The FRIA complements any DPIA where overlapping obligations are already met through data-protection assessment work.

Who registers high-risk AI systems in the EU database?

For covered Annex III high-risk systems, the provider or authorised representative registers itself and the system before market placement or putting into service. Public authorities, Union institutions, bodies, offices, agencies, and persons acting on their behalf must register themselves, select the system, and register their use before putting the system into service or using it.

What should an EU AI Act serious-incident file contain?

For high-risk systems, keep the event chronology, affected system, harm, affected persons or groups, provider and deployer notifications, authority notifications, corrective measures, logs, and post-market monitoring evidence. For GPAI models with systemic risk, the Commission template asks for start and end dates, harm, chain of events, model involved, evidence of involvement, response, recommendations, root cause analysis, and post-market monitoring patterns.

  • A FRIA is required before first deployment for specified deployers of Article 6(2) high-risk AI systems: bodies governed by public law, private entities providing public services, and deployers of certain Annex III essential-services systems, with the Annex III critical-infrastructure area excluded by Article 27.
  • The FRIA must describe the deployer process, period and frequency of use, affected groups, likely fundamental-rights risks, human oversight measures, and risk-response measures including internal governance and complaint mechanisms.
  • Article 49 registration applies before placing on the market or putting into service many Annex III high-risk systems, with separate provider, authorised-representative, and public-authority deployer registration routes.
  • For high-risk AI systems, providers must report serious incidents under Article 73; deployers that identify a serious incident must inform the provider first and then the importer or distributor and relevant market surveillance authorities.
Question 4

GPAI and transparency obligations

General-purpose AI model providers have a separate Chapter V rule set. Article 53 requires technical documentation, downstream information, a copyright-policy control, and a public summary of training content using the AI Office template. Providers of GPAI models with systemic risk also have Article 55 duties for model evaluation, systemic-risk assessment and mitigation, serious-incident tracking and reporting, and cybersecurity protection.

Transparency questions should be answered under Article 50, not treated as generic AI disclosure advice. The rule distinguishes direct human interaction, synthetic content marking by providers, notices for emotion recognition and biometric categorisation by deployers, deepfake disclosures, and AI-generated or manipulated public-interest text disclosures.

What does the EU AI Act require from GPAI model providers?

Article 53 requires GPAI model providers to maintain model technical documentation, provide downstream information needed by AI-system providers, maintain a policy for EU copyright compliance, publish a summary of training content using the AI Office template, and cooperate with the Commission and competent authorities.

What extra duties apply to GPAI models with systemic risk?

Article 55 adds model evaluation with state-of-the-art protocols and adversarial testing, assessment and mitigation of systemic risks at Union level, serious-incident tracking and reporting without undue delay, and adequate cybersecurity protection for the model and physical infrastructure.

When must users be told they are interacting with AI?

Article 50 requires providers of AI systems intended to interact directly with natural persons to design and develop the system so people are informed they are interacting with an AI system, unless that is obvious to a reasonably well-informed, observant, and circumspect person in the circumstances and context of use.

When must AI-generated content be labelled or disclosed?

Article 50 requires provider-side machine-readable marking for synthetic audio, image, video, or text outputs where the rule applies. Deployers must disclose deepfakes, and must disclose AI-generated or manipulated public-interest text unless a listed exception applies, such as human review or editorial control with editorial responsibility.

  • From 2 August 2025, obligations for GPAI providers enter into application for models placed on the market after that date; providers of GPAI models placed on the market before 2 August 2025 have until 2 August 2027 to comply.
  • Third-country providers of GPAI models must appoint an EU authorised representative before placing the model on the Union market, unless the open-source exception applies and the model does not present systemic risk.
  • Providers of AI systems that interact directly with natural persons must inform them they are interacting with an AI system unless that is obvious in context.
  • Providers of systems generating synthetic audio, image, video, or text must ensure outputs are marked in machine-readable format and detectable as artificially generated or manipulated, subject to the Article 50 exceptions.
Question 5

Practical evidence checklist for FAQ answers

A useful FAQ answer should leave behind enough evidence for product, legal, engineering, procurement, security, and compliance teams to reproduce the decision later. The evidence should identify the exact AI system or model, the operator role, the intended purpose, the market or output-use location, and the cited source that supports the answer.

Do not treat vendor claims, model cards, or policy summaries as a substitute for the applicable AI Act source. They can support implementation evidence, but the FAQ answer should still map the fact pattern to Article 2 scope, Article 3 roles, Article 5 prohibitions, Article 6 high-risk classification, Chapter V GPAI duties, Article 50 transparency, Article 27 FRIA, Article 49 registration, or incident duties as applicable.

What should an EU AI Act FAQ answer avoid?

Avoid unsupported deadlines, penalty figures, thresholds, exemptions, or authority routes. If the grounding source does not support the answer, mark the issue as unresolved instead of filling the gap from memory or vendor marketing.

What is the minimum useful evidence for an EU AI Act FAQ answer?

Keep the AI system or model name, intended purpose, operator role, risk classification, source citation, decision owner, affected launch or deployment, required artifact, approval history, and reassessment trigger for product, model, supplier, market, or legal changes.

  • Scope record: market, establishment, output-use location, operator role, affected persons, exclusions considered, and source citation.
  • Classification record: Article 5 screen, Article 6(1) product-safety route, Annex III use case, Article 6(3) derogation assessment if used, and profiling check.
  • High-risk record: provider obligations, deployer obligations, conformity assessment route, technical documentation, logs, human oversight, instructions for use, registration, FRIA, and incident escalation.
  • GPAI record: model provider identity, open-source status, systemic-risk assessment, technical documentation, downstream information, copyright policy, training-content public summary, authorised representative where needed, and AI Office submission route.
  • Transparency record: interaction notice, machine-readable synthetic-content marking, biometric or emotion-recognition notice, deepfake disclosure, public-interest text disclosure, accessibility, timing, and exception analysis.
