Who must comply with the EU AI Act? The Act can apply to providers that place AI systems or general-purpose AI (GPAI) models on the EU market, and to organizations that deploy AI systems under their authority. Some obligations also reach businesses established outside the EU when they supply a model or system into the Union market. Your duties depend on your legal role, the system and its purpose, where it is supplied or used, and the date that rule applies. Maximum penalties range from €7.5 million to €35 million or a percentage of worldwide annual turnover, whichever is higher, but those are statutory ceilings—not automatic or typical fines.
This FAQ explains the role-based scope, the main obligations, the staged timetable, enforcement powers and a practical way to assess your exposure. It covers the European Union AI Act only; other laws may apply at the same time.

The Act assigns responsibilities according to what an organization does with an AI system or model, rather than simply where it is incorporated. A company can have more than one role across different products or projects, so classification should be done system by system.
Providers
A provider is a natural or legal person that develops an AI system, or has one developed, and places it on the market or puts it into service under its own name or trademark. Provider obligations change with the system category. For a high-risk system, the provider must complete the required conformity assessment before market placement or putting the system into service and remains responsible for compliance throughout the system’s lifecycle.

Deployers
A deployer is a natural or legal person, public authority, agency or other body that uses an AI system under its authority. The definition covers business, occupational, trade and freelance use; a person who regularly uses AI to obtain an economic benefit can therefore be treated as a deployer. Employees following an organization’s instructions and control are not separate deployers for that organizational use. Personal, non-professional activity is excluded from the Article 50 deployer definition.
GPAI model providers
Providers that supply general-purpose AI models have a distinct set of duties. The Commission’s guidance indicates that the provider concept can include an entity outside the EU that places a GPAI model on the Union market. Compute or capability indicators discussed in guidance help explain scope, but they do not replace the full legal definition or a fact-specific assessment.

Importers, distributors and other participants can acquire duties in particular circumstances. An organization that substantially modifies a system, rebrands it or otherwise takes on a legally defined provider role may no longer be treated as a passive intermediary. The decisive questions are what the organization did, whose name the system uses, and where the system is supplied or operated.
Does the EU AI Act apply to my company?
Use a five-part analysis: identify the role, classify the system and purpose, map the market and use locations, check the applicable date, and identify the supervising authority and evidence required. EU establishment is not the only trigger; a non-EU business can still fall within scope when it places a covered model or system on the Union market.
- Map the role. Record whether each business unit is acting as provider, deployer, GPAI provider, importer, distributor or another value-chain actor.
- Describe the system and purpose. A general-purpose model, a system used for a specified high-risk purpose, a system requiring transparency, and a prohibited practice follow different rules.
- Map geography. Note where the model or system is placed on the market and where it is used. A company’s headquarters alone does not settle the question.
- Check the date. The Act is phased. A duty may already apply, have a transition period, or begin later for a particular category.
- Assign evidence and oversight. Determine which authority is competent and what documentation, human oversight, notices, monitoring and incident records are needed.
The European Commission describes its FAQs and guidance as implementation help. The binding regulation and any applicable implementing measures control the legal result, so a general answer cannot replace a fact-specific classification.
What AI Act duties apply to high-risk systems?
High-risk obligations divide between the provider that supplies the system and the deployer that operates it. The relevant high-risk dates depend on whether the system is a specified use case or is embedded in a regulated product.
Provider requirements
- Complete a conformity assessment before placing the system on the EU market or putting it into service.
- Operate a quality-management system proportionate to the legal requirements.
- Register the system where registration is required.
- Maintain post-market monitoring and processes for serious incidents and corrective action.
- Keep the technical and operational evidence needed to demonstrate conformity during the lifecycle.
Deployer requirements
- Use the system in accordance with the provider’s instructions.
- Monitor its operation and respond to identified risks or failures.
- Appoint a human-oversight person who has sufficient competence, authority and resources.
- Follow additional information, assessment or registration duties that apply to the organization or use case.
Public authorities and public-service deployers can face additional impact-assessment or registration obligations in specified cases. Workplace uses and decisions affecting individuals can also trigger information duties. The exact trigger depends on the system’s classification and context, not merely on the fact that AI is present.
What must GPAI model providers do?
GPAI providers have baseline obligations even when the model is not classified as having systemic risk. The Commission identifies three core deliverables: technical documentation, a copyright-compliance policy, and a sufficiently detailed public summary of training content.
Baseline GPAI duties
- Prepare and maintain the technical documentation required for downstream providers and authorities.
- Adopt a policy for complying with applicable copyright rules.
- Publish a sufficiently detailed summary of the content used to train the model.
Additional systemic-risk duties
Providers of models with systemic risk must meet additional requirements, including notification, risk assessment and mitigation, serious-incident reporting and cybersecurity protections. Whether a model reaches that category depends on the legal criteria and the evidence available for the particular model; an indicative capability or compute threshold in guidance is not a substitute for the complete test.
The Commission says GPAI obligations began applying on 2 August 2025. Its guidance describes a transition for models placed on the market before that date, with compliance due by 2 August 2027. Enforcement powers for GPAI obligations apply from 2 August 2026.

What transparency rules apply under Article 50?
Article 50 creates disclosure and marking duties for specified interactions and content. The obligation is not a universal label on every AI output; it is triggered by the kind of system, interaction or content and by whether the organization is a provider or deployer.
Provider-facing duties
Providers of systems that interact directly with people must inform them that they are interacting with AI. Providers also have duties to support machine-readable marking of certain generated or manipulated content so that it can be detected as such.
Deployer-facing duties
Deployers must make disclosures in specified situations, including use of emotion-recognition or biometric-categorization systems. They must also label deepfakes and certain AI-generated or manipulated text that is published to inform the public on matters of public interest.
The Commission states that Article 50 applies from 2 August 2026. A limited transition applies to certain marking obligations for qualifying systems placed on the market before that date; the Commission FAQ specifies 2 December 2026 for those providers. The transition does not erase other duties that may already apply to the system or actor.

The dates below are the Commission’s implementation overview as described after the AI Omnibus changes. Classification and the current legal text still matter: a date in the table does not turn an otherwise out-of-scope system into a regulated one.
| Obligation or milestone | Date described by the Commission | Practical meaning |
|---|---|---|
| Prohibited practices and AI-literacy provisions | 2 February 2025 | These provisions are already applicable as of 25 October 2026. |
| GPAI model-provider obligations | 2 August 2025 | Models placed on the market before this date have a transition described through 2 August 2027. |
| Article 50 transparency rules and relevant enforcement powers | 2 August 2026 | Some marking duties for qualifying pre-existing systems have a limited transition to 2 December 2026. |
| High-risk use cases in specified Annex III areas | 2 December 2027 | Confirm the system’s category and the current implementation text before relying on this date. |
| AI embedded in regulated products | 2 August 2028 | This covers systems embedded in products governed by the relevant product-safety legislation. |
What are the penalties for violating the EU AI Act?
The Commission publishes maximum ceilings. The amount imposed in an individual case is determined by factors including the infringement’s nature, gravity and duration; proportionality can be taken into account for SMEs and small mid-cap companies in Article 50 cases.
| Type of infringement | Maximum administrative penalty |
|---|---|
| Prohibited AI practices | €35 million or 7% of the offender’s total worldwide annual turnover, whichever is higher. |
| Other breaches, including GPAI obligations | €15 million or 3% of worldwide annual turnover, whichever is higher. |
| Failure to comply with an information request, or supplying incorrect, incomplete or misleading information in an AI-system case | Up to €7.5 million or 1% of worldwide annual turnover, whichever is higher. |
These figures are not typical fines and do not show how often penalties are imposed. They are statutory maximums. The authority must assess the facts and proportionality rather than automatically applying the highest number.
How is the AI Act enforced?
Enforcement is shared. The European Commission’s AI Office handles GPAI providers and specified related systems. National competent authorities handle other AI systems, while the European Data Protection Supervisor covers AI systems used by EU institutions.

A company should therefore be able to produce a coherent record of its role, classification, instructions, human oversight, monitoring and incident decisions rather than relying on informal assurances from a vendor.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should a company do first?
A defensible compliance program starts with an inventory and a decision log. The following sequence keeps legal classification ahead of tool procurement or policy drafting.
- Inventory every AI system and model. Include internally developed tools, embedded features, APIs, fine-tuned models and systems used by contractors or public-facing teams.
- Identify the contractual and operational owner. Record who developed the system, whose name or trademark appears, who placed it on the market and who controls day-to-day use.
- Describe each purpose and affected group. Document what the system does, whose decisions or interactions it influences, and whether it is used at work, in public services or for another regulated purpose.
- Classify the category. Test for prohibited practice, high-risk use, Article 50 transparency trigger, GPAI model or another category.
- Build a date matrix. Tie each duty to its application date and any transition, including the 2 December 2026 marking transition and the later high-risk dates.
- Assign controls and accountable people. Allocate conformity work, technical documentation, human oversight, monitoring, incident response, notices and registration tasks.
- Prepare for questions from authorities. Keep evidence of instructions, assessments, training, monitoring results, corrective actions and communications in a form that can be retrieved quickly.
- Review changes. Reassess classification when a model is materially modified, rebranded, moved into a new use case or supplied to a new market.
What mistakes create avoidable risk?
- Assuming an EU subsidiary is the only trigger. A non-EU provider can be covered when it places a model or system on the Union market. Map supply and use locations separately.
- Treating every user as a provider. Ordinary organizational use generally points to the deployer role; provider status can arise when the organization develops, rebrands or substantially modifies the system.
- Using a model’s marketing label as its legal category. “Copilot,” “assistant” or “general-purpose” does not by itself decide whether a use is high-risk or transparency-triggering.
- Waiting for the final deadline. Prohibited-practice and AI-literacy provisions already apply, and GPAI and Article 50 duties have their own dates and transitions.
- Budgeting from the maximum fine. A ceiling is not a forecast. Focus first on classification, evidence, oversight and the ability to correct problems.
- Ignoring other laws. The AI Act does not displace data-protection, product-safety, employment, consumer-protection or sector-specific requirements.
What is the practical answer for a business leader?
Do not begin by asking whether the company “uses AI” in the abstract. Ask which entity is supplying or operating which system, for what purpose, in which market, and on what date. That map determines whether the immediate task is a prohibition check, a GPAI documentation package, an Article 50 notice or marking process, a high-risk conformity and monitoring program, or a combination. Keep the classification tied to evidence and revisit it whenever the model, branding, deployment context or market changes.
Frequently Asked Questions
Are employees personally treated as deployers when they use an AI tool at work?
No, not for organizational use when they act under the organization’s instructions and control. The organization is the relevant deployer; a person using AI regularly for an independent business, trade, occupational or freelance activity may instead fall within the deployer definition.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Can one organization be both a provider and a deployer?
Yes. A company can provide a system under its own name and separately deploy that system, or another system, under its authority. Each role brings its own duties, so the same project may need both provider and deployer controls.
Does complying with the AI Act replace GDPR compliance?
No. The AI Act operates alongside data-protection, product-safety, employment, consumer-protection and sector rules. An AI Act conformity process does not by itself establish that personal-data processing or another regulated activity is lawful.
Are the published penalty amounts what companies usually pay?
No. The European Commission describes them as maximum ceilings. The eventual amount depends on the infringement’s nature, gravity and duration, with proportionality considered in the circumstances specified by the Act.
