Law / proposed law in Greece

Regulation (EU) 2024/1689 of the European Parliament and of the Council on harmonised rules on artificial intelligence (the EU AI Act) was published in the Official Journal of the European Union on 12 July 2024. It entered into force on 1 August 2024, although many of its provisions come into force on specific dates:

2 February 2025: General provisions and provisions relating to prohibited AI practices and AI literacy (Chapters I and II).
2 August 2025: Provisions relating to general-purpose AI (GPAI) models, governance and competent authorities (Chapters V and VII), and penalties (Chapter XII).
2 August 2026: Original enforcement date for most of the AI Act's remaining provisions, including the requirements for Annex III high-risk AI systems, AI regulatory sandboxes (Article 57(1)), and certain transparency obligations relating to chatbots, deepfakes and AI-generated content. However, under the Digital Omnibus for AI (defined below), the timeline for Annex III high-risk AI systems is extended to 2 December 2027, with a further extension to 2 August 2030 for high-risk AI systems intended to be used by public authorities. Similarly, the watermarking obligations imposed on generative AI content (Article 50(2)) are extended to 2 December 2026.
2 August 2027: Original enforcement date for provisions relating to high-risk AI systems that are safety components of products or products themselves (i.e., AI systems covered by Annex I). However, under the Digital Omnibus for AI (defined below), the timeline for Annex I high-risk AI systems is extended to 2 August 2028, with a further extension to 2 August 2030 for high-risk AI systems intended to be used by public authorities.

AI compliance in Greece

In July 2026, Greece enacted the law titled ‘Implementing Measures for Regulation (EU) 2024/1689 of the European Parliament and of the Council of 13 June 2024 (the AI Act) – Amendments to Law 4961/2022 and Other Provisions’ (Government Gazette A' 114/20 July 2026, hereinafter the Greek AI Act Implementation Law or the Law). The new law establishes the national legal framework for the implementation of the AI Act in Greece, while simultaneously repealing Chapter B of Part A of Law 4961/2022, which had constituted the first legislative attempt to regulate issues relating to the development and use of artificial intelligence. It is also worth noting that, in Opinion No. 9/2026 on the draft Law, the Hellenic Data Protection Authority (HDPA) welcomed the proposed supervisory framework while stressing that the effective implementation of the AI Act would require adequate organisational, financial and human resources.

The Law establishes the institutional, supervisory and enforcement framework for the application of the AI Act in Greece and designates the competent national authorities responsible for market surveillance and regulatory oversight. It further establishes a dedicated coordination and expertise centre for artificial intelligence and provides mechanisms for the submission and handling of complaints relating to AI systems. In addition, the Law requires the registration of AI systems used by public sector entities and strengthens the monitoring of AI developments at national level. In addition, the Law provides for the establishment of an AI Regulatory Sandbox to support innovation and the testing of AI systems under regulatory supervision. However, at the time of writing, there is no official confirmation that the sandbox is operational. Taken together, these measures form the core of Greece's national AI governance framework and seek to ensure the effective implementation of the AI Act.

Furthermore, regarding the use of artificial intelligence systems in the educational process and the protection of personal data, Greece has adopted Joint Ministerial Decision No. 55909/Δ6 (Government Gazette B΄ 2639/12.05.2026) (the Decision). The Decision applies to all secondary schools in Greece and requires that AI systems be used solely as tools to support teaching and learning under human supervision. It prohibits, inter alia, the fully automated assessment of students or teachers, the profiling of students and educators, and the submission of AI-generated content as a substitute for students’ own work. In addition, the Decision imposes specific transparency, security and data protection obligations, including the conduct of prior impact assessments, the implementation of data minimisation measures, restrictions on the input of personal data into AI systems, mandatory training for teachers, awareness-raising activities for students, and safeguards against misinformation, algorithmic bias and harmful content.

A new EU Product Liability Directive, Directive (EU) 2024/2853 of the European Parliament and of the Council of 23 October 2024 on liability for defective products (Product Liability Directive), was published in the Official Journal of the European Union on 18 November 2024 and entered into force on 8 December 2024. Member States have until 9 December 2026 to implement the Product Liability Directive into national law. The Product Liability Directive modernises the EU-level strict product liability regime, preserving the core principles of the previous law while adapting to new technologies by extending the scope to include software and AI. This regime is still limited to certain types of damages and applies only to consumers and other natural persons.

On 24 July 2026, the Council of the European Union adopted the proposal for a Regulation of the European Parliament and of the Council amending Regulations (EU) 2024/1689 and (EU) 2018/1139 as regards the simplification of the implementation of harmonised rules on AI (Digital Omnibus for AI). The Digital Omnibus for AI was published in the Official Journal of the European Union on 24 July 2026 (OJ L, 2026/1744) and entered into force on 27 July 2026. Key elements include:

a new prohibition on non-consensual intimate AI-generated content and child sexual abuse material;
extension of small and medium-sized enterprise (SME) regulatory exemptions to small mid-caps;
clarification of the AI Office’s supervisory powers over general-purpose AI models, including enforcement powers over AI systems embedded in very large online platforms (VLOPs) and very large online search engines (VLOSEs), and centralisation of enforcement of certain GPAI systems within the AI Office; national competent authorities retain jurisdiction over law enforcement, border management, the judiciary, and financial institutions;
clarification of the AI literacy obligation;
reduced administrative burden (e.g., registration simplification for non‑high‑risk systems falling into Article 6(3) exemptions); and
extension of access to AI regulatory sandboxes, including through an EU-level sandbox, with national competent authorities required to establish AI regulatory sandboxes by 2 August 2027.

The Commission’s 2022 proposal on adapting non-contractual civil liability rules to artificial intelligence (COM(2022) 496) (AI Liability Directive) was withdrawn under the Commission Work Programme 2025 (COM(2025) 45 final, Annex IV), with the withdrawal formalised in the Official Journal in October 2025. No replacement proposal is currently tabled. As proposed, the AI Liability Directive would have complemented the EU AI Act and the revised Product Liability Directive by harmonising national civil liability regimes and rules on the burden of proof in relation to AI. However, this ambitious project was ultimately abandoned, notably due to the significant divergence across Member States’ legal frameworks.

On 22 June 2026, the European Parliament and Council reached a provisional agreement on a Directive aimed at combating the sexual abuse and sexual exploitation of children and child sexual abuse material (CSAM) (CSAM Directive). The CSAM Directive updates existing offences and introduces new criminal offences to address technological developments and emerging forms of CSAM, including the criminalisation of the production, possession, and dissemination of instructions on how to commit child sexual abuse or produce CSAM. The CSAM Directive also establishes offences related to AI, making it unlawful to design, adapt, acquire, possess, or distribute AI systems intended to generate CSAM. Additional offences include paying for access to livestreamed child sexual abuse, livestreaming such abuse, organising travel for the purpose of child sexual abuse, and sexual extortion of children through threats to disclose CSAM. The Directive expands provisions on grooming, criminalising soliciting a child to produce or share CSAM, and increases penalties for offences such as the acquisition, possession, or access to CSAM, as well as its distribution or dissemination.

On 3 June 2026, the European Commission published a proposal for a Regulation establishing a framework of measures for strengthening Europe’s cloud and AI ecosystem (Cloud and AI Development Act or CADA) (COM(2026) 502 final). CADA is addressed at the EU's limited computing capacity and dependence on non-European cloud providers, and aims to increase sustainable computing capacity, ensure data sovereignty and operational continuity, and enhance public sector resilience. While the EU AI Act regulates AI systems and GPAI models, CADA focuses on cloud and AI computing services and their underlying infrastructure. It establishes a four-level Union cloud computing sovereignty framework, with higher levels requiring that data generated by audited services cannot be used to train AI systems operated by entities outside the European Economic Area (EEA). The proposal also establishes ‘Cloud and AI Leadership Initiatives’ supporting frontier, physical, and industrial AI development. The AI Board would coordinate AI adoption activities under CADA.

Product Liability Directive in Greece

Lastly, it should be noted that Greece has not yet transposed the revised Product Liability Directive into national law.

Regulatory guidance / voluntary codes

Regulatory guidance / voluntary codes in Greece

In order to ensure the consistent, effective, and uniform application of the EU AI Act across the European Union, the European Commission has published various guidelines and codes of practice. These are non-binding, as only the Court of Justice of the European Union has authoritative interpretation powers. Codes of practice are voluntary compliance tools which help demonstrate compliance with binding AI Act obligations.

The Commission has published the following guidelines:

4 February 2025: Guidelines on prohibited AI practices;
6 February 2025: Guidelines on AI system definition;
18 July 2025: Guidelines on the scope of obligations for general-purpose AI model providers;
19 May 2026: Draft guidelines on the classification of high-risk AI systems (High-Risk Classification Guidelines) (see the High-risk AI section);
20 July 2026: Guidelines on the implementation of the transparency obligations for certain AI systems under Article 50 of the EU AI Act (Article 50 Guidelines) (see the User transparency section).

The Commission has also published the following codes of practice:

10 July 2025: General-purpose AI Code of Practice; and
10 June 2026: Code of Practice on Transparency of AI-Generated Content (Transparency Code of Practice) (see the User transparency section).

Under Article 95 of the EU AI Act, providers of AI systems that do not fall under the high-risk classification, as well as deployers, have the possibility to adopt voluntary codes of conduct in order to adopt, on a non-binding basis, technical solutions and industry best practices. Because of this, it is expected that the AI Office will issue further codes of conduct for this purpose.

To provide organisations with support identifying and implementing AI literacy initiatives, on 4 February 2025 the Commission launched a repository of AI literacy practices.

In May 2024, the Council of Europe adopted the Framework Convention on Artificial Intelligence and Human Rights, Democracy and the Rule of Law (Framework Convention) (CETS No. 225). The Framework Convention was opened for signature on 5 September 2024 in Vilnius, and the European Union signed the same day pursuant to Council Decision (EU) 2024/2218. It is an international, legally binding treaty aiming to ensure that activities within the lifecycle of AI systems are fully consistent with human rights, democracy, and the rule of law, whilst being conducive to technological progress and innovation.

AI compliance in Greece

In November 2024, the High-Level Advisory Committee on Artificial Intelligence, established in November 2023 under the supervision of the Greek Prime Minister, published Greece’s national AI strategy, titled ‘A Blueprint for Greece's AI Transformation’ (the AI Strategy).

The AI Strategy sets out a comprehensive set of principles for ensuring that AI systems are effective and are developed and used responsibly throughout their lifecycle. These principles:

stress the importance of first confirming that AI is truly necessary for the given solution, ensuring that the project is feasible, and using high-quality data for training algorithms;
emphasize the need for clear processes and rules governing data access, alignment among stakeholders, and defining success through key performance indicators and risk-value assessments;
highlight the importance of appropriate infrastructure, organisation, and workforce for the deployment of AI, while continually evaluating the interpretability and added value of the AI system; and
address crucial aspects of responsible AI, including monitoring security risks, complying with legal and data regulations, ensuring ethical alignment, and fostering environmental sustainability throughout the AI system’s development and implementation.

Looking ahead, the report ‘Generative AI Greece 2030’ examines the future landscape of generative AI in Greece by 2030. Authored by the National Centre for Social Research (EKKE) and the National Centre for Scientific Research, with support from the Special Secretariat of Foresight, the report proposes co-creating voluntary guidelines for public authorities, social partners and other stakeholders. These guidelines aim to align AI development with ethical principles and reduce the risk of socio-economic divides arising from unequal access to AI. The report also calls for ethical oversight mechanisms that promote societal values, safety, transparency, innovation and human welfare, while tackling digital inequality and algorithmic discrimination.

In the healthcare sector, the National Commission for Bioethics & Technoethics of Greece has issued its ‘Opinion on the Applications of Artificial Intelligence in Health in Greece’. This opinion sets out guidelines requiring AI applications to adhere to fundamental ethical principles, including:

Autonomy: respecting patients' right to informed decision-making while safeguarding privacy and consent;
Beneficence and No Harm: improving health outcomes or diagnostics without causing harm;
Safety: implementing strict quality control to prevent errors;
Fairness: ensuring equitable distribution of AI benefits in healthcare;
Equality: providing equal access to AI-based healthcare for all;
Prevention and Precaution: ceasing AI use if risks are identified or remain uncertain;
Explainability: ensuring that AI decisions are transparent, interpretable and accountable;
Complementarity: ensuring that AI supports, but does not replace, human medical judgement.

Turning to education, in March 2025, the National Commission for Bioethics & Technoethics of Greece issued its ‘Opinion on the Use of Artificial Intelligence in Greek Schools’, setting out ethical guidelines and policy recommendations for the use of AI in primary and secondary education. The Opinion identifies the following as fundamental principles governing the responsible use of AI in schools: respect for human dignity, autonomy, beneficence and non-maleficence, equitable access, complementarity, transparency, sustainability, augmentation over automation and inventiveness over repetition.

At the tertiary level, several Greek university faculties have published their own AI guidelines for students and staff. Institutions including the University of Crete, the National and Kapodistrian University of Athens, the University of Macedonia, the Aristotle University of Thessaloniki and the University of Western Attica permit AI as an assistive tool, provided users fully disclose AI involvement, critically evaluate outputs and respect intellectual property. Submitting AI-generated content as original work without acknowledgment constitutes academic misconduct comparable to plagiarism and may result in institutional sanctions.

To promote public understanding of AI, the Ministry of Digital Governance and Artificial Intelligence published the guide ‘Artificial Intelligence for Everyone’ in May 2026. Developed in cooperation with the National Council for Research, Technology and Innovation and the Special Secretariat for Artificial Intelligence and Data Governance, this guide was authored by leading Greek AI scientists and made available through the national AI portal. It explains core AI concepts, including generative AI and large language models, through practical examples and accessible guidance, offering recommendations for effective and responsible use of AI-powered tools. This initiative supports the government's broader strategy to enhance digital skills, raise public awareness of AI technologies and facilitate their safe adoption across society.

Similarly, the HDPA has launched a few educational initiatives to promote compliance with the new legislative framework. These include the publication of educational materials and the development of training programmes on AI and data protection, including dedicated curricula for Data Protection Officers, privacy professionals and ICT professionals involved in the development of AI systems.

For the business community, the Hellenic Federation of Enterprises (SEV) has published a ‘Guide on the Use of AI for Businesses’. Designed to help Greek enterprises understand and integrate AI effectively, the guide addresses practical implementation, business benefits, including productivity gains, revenue growth and cost reduction, and workforce empowerment. It also examines strategic considerations, challenges and prerequisites for successful AI adoption across various sectors.

In the research sector, the Hellenic Academic Libraries Link (HEAL-Link) issued guidance in March 2026 entitled ‘Use of Artificial Intelligence for Research Purposes and Publication of Research Results’. This guidance provides recommendations on responsible use of generative AI tools throughout the research lifecycle and promotes transparency by requiring disclosure of AI-assisted contributions in research outputs. Finally, in the advertising sector, the Hellenic Association of Communication Agencies (EDEE) and the Hellenic Advertisers Association (SDE) have jointly published a best practice guide titled ’10 Principles for the Responsible Use of Artificial Intelligence in Advertising’. This guide is addressed to advertising agencies and individuals promoting products or services.

Appointed supervisory authority in Greece

European Level

The European Commission established the European AI Office (AI Office) on 24 January 2024. The AI Office is a European Commission function and forms part of the Directorate-General for Communications Networks, Content and Technology; it must therefore operate in accordance with the Commission's internal processes. The AI Office is responsible for assisting the European Commission with the oversight, monitoring, and enforcement of requirements for GPAI models and systems. Under the Digital Omnibus for AI, the AI Office has been granted enforcement powers over AI systems embedded in VLOPs and VLOSEs, and certain GPAI systems enforcement is centralised within the AI Office. It is primarily made up of hired full-time staff from a range of backgrounds such as technology specialists, economists, policy specialists, and lawyers.

In addition, the European Artificial Intelligence Board (AI Board) has been established under Article 65 of the EU AI Act. The AI Board's core responsibility is to advise and assist the Commission and Member States to facilitate the consistent and effective application of the EU AI Act. The AI Board includes a representative from each Member State, and the AI Office and the European Data Protection Supervisor participate as non-voting observers.

Member State Level

Article 70 of the EU AI Act concerns the designation of national competent authorities by EU Member States. It specifies that each Member State shall establish or designate as national competent authorities at least one notifying authority and at least one market surveillance authority for the purposes of the general supervision and enforcement of the EU AI Act. Where multiple market surveillance authorities are appointed, one of the market surveillance authorities must act as the single point of contact. The authorities must operate independently and without bias. Member States were required to notify the Commission of their appointed authorities and publicly available information on how to contact them by 2 August 2025, and must report to the Commission on the financial and human resources of their competent authorities by the same date and every two years thereafter (Article 70(6)). The designation of national authorities has been slower than expected, which may affect early enforcement consistency.

Supervisory authority in Greece

Prior to the enactment of the Greek AI Act Implementation Law, Greece had not met the 2 August 2025 deadline for designating the national competent authorities and fulfilling the related notification obligations under Article 70 of the AI Act. The Law addresses this gap by establishing the national governance framework for the supervision and enforcement of AI systems and formally designating the competent authorities referred to in this section.

In particular, the Law designates the HDPA as the competent market surveillance authority pursuant to Article 70(1) of the AI Act in respect of:

AI systems falling within the prohibited AI practices set out in Article 5 of the AI Act;
high-risk AI systems referred to in Annex III to the AI Act; and
AI systems subject to transparency obligations pursuant to Article 50 of the AI Act.

An exception applies to high-risk AI systems that are safety components of, or themselves constitute, products covered by Union harmonisation legislation listed in Annex I, Section A of the AI Act. In such cases, the market surveillance authorities already designated under the relevant national sector-specific legislation retain competence to supervise AI Act compliance within their respective areas.

The HDPA is also designated as Greece’s single point of contact pursuant to Article 70(2) of the AI Act.

For conformity assessment purposes, the Hellenic Telecommunications and Post Commission (EETT) is designated as the national notifying authority under Article 28 of the AI Act, exercising all powers assigned to notifying authorities under the Regulation. The HDPA also acts as a notified body, responsible for conducting conformity assessments under Annex VII of the AI Act for high-risk AI systems intended for deployment by law enforcement, migration and asylum authorities.

Regarding the protection of fundamental rights, Greece designated the following authorities in November 2024 to supervise and enforce Union law obligations, including the right to non-discrimination, in relation to high-risk AI systems under Annex III of the AI Act:

The Hellenic Data Protection Authority (ΑΠΔΠΧ);
The Greek Ombudsman (Συνήγορος του Πολίτη);
The Hellenic Authority for Communication Security and Privacy (ΑΔΑΕ); and
The National Commission for Human Rights (EEΔΑ).

These bodies cooperate with the HDPA in its capacity as the competent market surveillance authority and exercise the powers set out in Article 77 of the AI Act.

Greece has also taken steps to strengthen its broader institutional AI governance framework. Following an announcement by the Prime Minister in June 2025, the Ministry of Digital Governance was renamed the Ministry of Digital Governance and Artificial Intelligence. At the same time, a Special Secretariat for Artificial Intelligence and Data Governance was established within the Ministry, with responsibility for supporting the development, coordination and implementation of national policies on artificial intelligence and data governance.

Definitions

Definitions in Greece

AI System

Article 3(1) of the EU AI Act defines an 'AI system' as follows:

"a machine-based system that is designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment, and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments".

The EU AI Act uses a technology-neutral definition, focusing on the effect of the system rather than the techniques used. There are several key features of the definition which, acting together, distinguish the AI system from more traditional software systems. The central characteristics are the level of autonomy and adaptiveness in how the system operates and the ability for the system to infer how to generate outputs. So, an AI system must be able to operate independently at some level (like many existing technologies) but must also be able to apply logic to draw conclusions from data it is given. It may also adapt after deployment, in effect by continuing to ‘learn’. These features are more akin to human capability than traditional technology systems, which operate using more fixed and pre-determined paths to process data. These outputs must influence physical or virtual environments, whether by making decisions or through other means.

The EU AI Act also sets out specific rules for GPAI models. GPAI models differ from AI systems; they can be an essential component integrated into an AI system, but do not themselves constitute an AI system until further components are added (such as an interface). For more information, see the Controls on generative AI section.

Provider

Article 3(3) of the EU AI Act defines a 'provider' as follows:

"a natural or legal person, public authority, agency or other body that develops an AI system or a general-purpose AI model or that has an AI system, or a general-purpose AI model developed and places it on the market or puts the AI system into service under its own name or trademark, whether for payment or free of charge".

Those falling within this definition as a ‘provider’ have significant responsibility for ensuring compliance with the EU AI Act, and so identifying the provider will be crucial for businesses and may well influence their choice of business/deployment model.

The provider is responsible for putting the AI on the market either by making it first available in the market or by directly putting the AI into use for its own purposes and under its own name or trademark. An organisation may also become a downstream provider if it makes substantial modifications to a system or changes its intended purpose (Article 25(1)). Guidance from the European Commission is expected on what counts as a ‘substantial modification’. At this stage, the only conclusive criterion is that such modification must not have been foreseen by the provider in the initial conformity assessment carried out by the provider.

Payment is not relevant, which will impact GPAI models supplied onto the market on an open-source basis or under free commercial terms.

Deployer

Article 3(4) of the EU AI Act defines a 'deployer' as follows:

"a natural or legal person, public authority, agency or other body using an AI system under its authority except where the AI system is used in the course of a personal non-professional activity".

In simple terms, a 'deployer' is an entity that uses an AI system other than for personal, non-professional use. Although the burden of responsibility on a deployer is not as great as on providers, there are still obligations that it must fulfil.

Note that the EU AI Act also implements requirements for organisations performing other roles (as distributor, importer, product manufacturer, and authorised representative). Together with the deployer and provider, such organisations are referred to as 'operators' of AI. Importantly, the same operator may qualify simultaneously as more than one of these roles if they meet the respective conditions. For instance, it is possible to be both the provider and the deployer of an AI system at the same time.

Prohibited activities

Prohibited activities in Greece

Certain AI practices are banned outright under Article 5 of the EU AI Act due to their potential for harm and ethical concerns. These prohibitions aim to protect EU citizens from the most intrusive and potentially abusive uses of AI.

Under Article 5, these uses and technologies include:

Subliminal techniques: Deploying subliminal techniques or techniques that are manipulative or deceptive and have the effect or objective of materially distorting a person’s behaviour by impairing their ability to make an informed decision, causing them to make a decision they would not otherwise have taken, in a manner that causes significant harm to them or others (or is reasonably likely to do so).
Exploiting vulnerabilities: Exploiting vulnerabilities of specific groups due to age, disability, or social or economic situation – as with subliminal techniques, this must have the effect or objective of materially distorting behaviour and cause significant harm to them or others (or be reasonably likely to do so).
Social scoring: Evaluating or classifying natural persons or groups based on their social behaviours or personality characteristics (known, inferred, or predicted) leading to either or both, unfavourable treatment of them or others in social contexts unrelated to the context in which the data was originally gathered or that is unjustified or disproportionate to their social behaviour or its gravity.
Crime profiling: Assessing the risk of an individual committing a crime, based on the profiling of that person and assessing their personality traits (as opposed to using such systems to support a human assessment of the involvement of a person).
Facial recognition databases: Creating or expanding facial recognition databases through untargeted scraping of facial images from the internet or CCTV footage.
Inferring emotions: Inferring emotions in workplaces and educational institutions (except for medical or safety reasons).
Biometric categorisation: Categorising natural persons based on their biometric data to deduce or infer sensitive information about them (i.e., their race, political opinions, trade union membership, religious or philosophical beliefs, sex life, or sexual orientation) except where based on lawfully acquired datasets (including in law enforcement).
Biometric identification: Engaging in ‘real-time’ biometric identification systems in publicly accessible spaces for law enforcement purposes, except under specific exempt circumstances.
As a new prohibited practice introduced by the Digital Omnibus for AI, Non-consensual intimate AI-generated content and CSAM: Placing on the market, putting into service, or using AI systems that (i) are intended to create, generate, or manipulate, or (ii) are designed or capable such that the creation, generation, or manipulation is a reasonably foreseeable outcome without adequate technical safeguards, non-consensual intimate content of natural persons (including non-consensual intimate deepfakes) or child sexual abuse material. Companies must comply with this prohibition by 2 December 2026.

High-risk AI

High-risk AI in Greece

Article 6 of the EU AI Act sets out classification rules for high-risk AI systems, stating that high-risk AI systems fall within two categories: (i) safety components of products or products themselves regulated by existing EU product safety laws (listed in Annex I, e.g., medical devices, automotive AI); or (ii) systems used in specified areas (listed in Annex III), namely:

Critical infrastructure: AI systems used as safety components in the management or operation of critical digital infrastructure, road traffic, or the supply of water, gas, heating, or electricity.
Education and vocational training: AI systems that determine access to education or training or otherwise impact a person's future opportunities and career development, and AI systems used for monitoring and detecting prohibited behaviour during tests.
Employment and worker management: AI systems used in hiring (including the placement of targeted job advertisements), performance evaluation, promotion, or termination decisions.
Access to essential private and public services: AI systems that evaluate eligibility for essential public services, such as social security and healthcare, as well as AI systems for evaluating and classifying emergency calls and dispatching emergency services. Additionally, AI systems used to evaluate creditworthiness or during the risk assessment and pricing of life and health insurance.
Law enforcement: AI systems used by law enforcement for risk assessments, predicting criminal activities (the risk of individuals becoming victims of crime, risk of (re-)offending, or otherwise during criminal investigations), for polygraphs (i.e., 'lie detectors' or similar tools), and assessing reliability of evidence.
Border control and migration: AI systems used to assess visa applications, asylum claims, and border security, including for polygraphs (i.e., 'lie detectors' or similar tools), and for detecting, recognising, or identifying individuals in migration contexts.
Judicial and democratic processes: AI systems assisting judicial authorities with researching and interpreting facts and the law and applying the law to a set of facts, as well as AI systems used for influencing the outcome of elections or referendums or voting behaviour.
Biometric identification and categorisation: AI systems that perform remote biometric identification, are used to categorise individuals based on biometric data or other sensitive or protected attributes, or are used for emotion recognition purposes.

Chapter III, Section 2 of the EU AI Act (Articles 9 to 15) imposes mandatory requirements on high-risk AI systems, including risk management systems (Article 9), data governance (Article 10), technical documentation (Article 11), record-keeping and logging (Article 12), transparency and information to deployers (Article 13), human oversight measures (Article 14), and accuracy, robustness, and cybersecurity (Article 15). Providers must also implement quality management systems (Article 17) and post-market monitoring (Article 72).

The European Commission has the power to amend the abovementioned categories of high-risk AI systems, including to modify any existing use cases or add new ones (Article 7(1) of the EU AI Act).

The Digital Omnibus for AI clarifies the definition of ‘safety component’ (Article 3(14)), specifying that an AI system fulfils a safety function only where its intended purpose is to prevent or mitigate risks to health and safety. AI systems used solely for non-safety-related functions such as user assistance, performance optimisation, service efficiency, automation, convenience, or quality control do not qualify as safety components.

The 19 May 2026 High-Risk Classification Guidelines are intended to assist providers, deployers, and market surveillance authorities in determining whether an AI system qualifies as high-risk. They provide interpretation of key classification concepts and practical examples.

Where an AI system falls into one of the two abovementioned categories of high-risk AI systems but does not pose significant risk of harm to health, safety, or fundamental rights, the operators of such AI systems are relieved from the requirements imposed for high-risk AI systems (except for the EU database registration). However, to benefit from such exemption, a thorough assessment must be documented and strict conditions must be met (the 19 May 2026 High-Risk Classification Guidelines published in May 2026 provide interpretive guidance). Importantly, providers claiming this exemption under Article 6(3) must still register the AI system in the EU database pursuant to Article 49(2). The Digital Omnibus for AI maintains this mandatory registration requirement for effective market surveillance and public accountability, but simplifies the registration process.

The Digital Omnibus for AI extends the deadlines for high-risk AI system requirements. Specifically:

for Annex III high-risk AI systems, the requirements apply from 2 December 2027 (extended from 2 August 2026);
for Annex I high-risk AI systems, the requirements apply from 2 August 2028 (extended from 2 August 2027); and
for high-risk AI systems intended to be used by public authorities, providers and deployers must comply with the EU AI Act requirements by 2 August 2030.

General-Purpose AI Models

Article 3(63) of the EU AI Act defines a GPAI (general-purpose AI) model as an:

"AI model, including where such an AI model is trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable of competently performing a wide range of distinct tasks regardless of the way the model is placed on the market and that can be integrated into a variety of downstream systems or applications, except AI models that are used for research, development or prototyping activities before they are placed on the market."

GPAI models are versatile and can be applied across various domains and contexts. The Act sets requirements to ensure that these specific models, due to their broad applicability and the wide range of tasks they can complete, adhere to high ethical and safety standards. Please note that not all AI models are GPAI models, and the EU AI Act only regulates the latter.

General-Purpose AI Models with Systemic Risk

Article 3(65) of the EU AI Act defines 'systemic risk' as:

"a risk that is specific to the high-impact capabilities of general-purpose AI models, having a significant impact on the Union market due to their reach, or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or the society as a whole, that can be propagated at scale across the value chain".

Article 51 of the EU AI Act classifies a GPAI model as having systemic risk if it has high-impact capabilities (this is presumed when the cumulative amount of computation used for training exceeds 10^25 floating point operations (FLOPs), though the Commission may also designate models based on other indicators and benchmarks) or based on a decision of the Commission.

Systemic risk involves the broader, cumulative impact of GPAI models on society. This encompasses scenarios where GPAI models could lead to significant disruptions or risks, necessitating a regulatory focus to prevent widespread adverse effects and ensure resilience across sectors. In view of the higher risks, the Act sets additional requirements for GPAI models with systemic risk.

Importantly, the requirements of a GPAI model/system (i.e., without a specific use case) and the requirement of an AI system based on its risk profile (depending on the use case at stake) can be cumulative. For instance, if the provider of a GPAI model integrates its model in a high-risk AI system, then the rules for both GPAI models and high-risk AI systems should be complied with.

Enforcement / fines

Enforcement / fines in Greece

The EU AI Act enforces compliance through a structured framework of fines and sanctions, varying in severity based on the nature of the non-compliance. Member States were required to lay down rules on penalties (including administrative fines) and notify them to the Commission by 2 August 2025.

For non-compliance with prohibited AI practices (see the Prohibited activities section), fines can reach up to EUR 35 million or 7% of the total worldwide annual turnover, whichever is higher.

Breaches of high-risk AI system requirements (see the High-risk AI section) can incur fines up to EUR 15 million or 3% of the total worldwide annual turnover.

Other non-compliance issues, such as providing incorrect or misleading information, can result in fines up to EUR 7.5 million or 1% of the total worldwide annual turnover. This applies to breaches not covered by the highest or significant sanctions. Reduced fine caps apply to SMEs and start-ups.

Enforcement / fines in Greece

Although Greece initially failed to meet the 2 August 2025 deadline for adopting national rules on penalties and enforcement measures, the Greek AI Act Implementation Law addresses this omission by establishing the national enforcement and sanctions regime required under Article 99 of the AI Act. As part of that regime, the Law confers additional administrative corrective and sanctioning powers on the HDPA and the other designated market surveillance authorities, alongside the market surveillance powers already provided for under the AI Act and Regulation (EU) 2019/1020.

More specifically, the competent authorities may issue warnings where an AI system intended to be placed on the market or put into service is likely to infringe the AI Act or the Greek AI Act Implementation Law. Where an infringement has already occurred, they may issue reprimands or binding compliance orders requiring operators to bring the AI system into compliance in a specified manner or within a specified period.

The Law further empowers the HDPA and the other market surveillance authorities to impose the administrative fines provided for in Article 99 of the AI Act to both private and public entities. In addition, they may threaten or impose periodic penalty payments when operators do not comply with competent authorities’ binding compliance orders, of up to two per cent of the undertaking’s average daily worldwide turnover or income during the preceding financial year. However, the practical application of the sanctions regime may give rise to interpretative questions, particularly as regards the delineation of competences between the designated authorities and the coexistence of the AI Act enforcement regime with existing national sector-specific legislation. Notably, these corrective and sanctioning measures may also be imposed on public sector bodies, ensuring that public authorities deploying or operating AI systems are subject to the same enforcement tools.

When exercising their sanctioning powers, the competent authorities must ensure that penalties are effective, proportionate and dissuasive in each individual case.

In addition, the Greek AI Act Implementation Law further enhances the enforcement powers of the HDPA by incorporating, mutatis mutandis, the investigative and corrective powers provided under Articles 15(4) and 15(5) of Law 4624/2019. These powers enable the HDPA to issue warnings and binding compliance orders, impose temporary or permanent restrictions or prohibitions, require the surrender of documentation and technical systems, seize relevant equipment and records, and order the discontinuation, freezing or destruction of data and related filing systems where necessary to remedy non-compliance.

The Greek AI Act Implementation Law further reinforces compliance through a mandatory publication regime for enforcement decisions. The HDPA and the other market surveillance authorities must publish sanctioning decisions identifying the infringement, the sanctions imposed and the infringing party.

Finally, the Greek AI Act Implementation Law enables the HDPA and the other designated market surveillance authorities to recover the costs incurred in investigating and establishing instances of non-compliance. Recoverable costs include, among others, the costs of testing AI systems, implementing market surveillance measures and managing non-compliant products prior to their placement on the market.

User transparency

User transparency in Greece

Article 50 of the EU AI Act sets out transparency obligations for providers and deployers of certain AI systems, which include that:

Article 50(1): providers of AI systems must ensure that natural persons using an AI system are informed that they are interacting with an AI system unless this is obvious to the natural person (this obligation excludes AI systems authorised by law to detect, prevent, investigate, or prosecute criminal offences).
Article 50(2): providers of AI systems, including general-purpose AI systems, generating synthetic audio, image, video, or text content must ensure that the outputs are marked in a machine-readable format and detectable as artificially generated or manipulated. This obligation excludes AI systems that perform an assistive function for standard editing, AI systems that do not substantially alter the input data, and AI systems authorised by law to detect, prevent, investigate, or prosecute criminal offences. Providers must also process data in accordance with other relevant EU laws.
Article 50(3): deployers of emotion recognition or biometric categorisation systems must inform the affected natural persons.
Article 50(4): deployers of AI systems that generate or manipulate image, audio, or video content constituting deepfakes must disclose that the content has been artificially generated or manipulated. For content forming part of an evidently artistic, creative, satirical, fictional, or analogous work or programme, this disclosure must be made in an appropriate manner that does not hamper the display or enjoyment of the work.
Article 50(5): deployers of AI systems that generate or manipulate text published to inform the public on matters of public interest must disclose that the text has been artificially generated or manipulated. This obligation does not apply where the AI-generated content has undergone human review or editorial control and a natural or legal person holds editorial responsibility for the publication.

These obligations apply from 2 August 2026 (except for the watermarking obligation under Article 50(2), for which providers of AI systems placed on the market before 2 August 2026 have until 2 December 2026 to comply).

The Transparency Code of Practice, published on 10 June 2026, is a voluntary instrument that sets out practical steps to help providers and deployers of generative AI systems meet the Article 50 transparency obligations. The Code is structured into two sections: Section 1 addresses provider obligations under Article 50(2), covering the marking and detection of AI-generated or manipulated content through machine-readable solutions; Section 2 addresses deployer obligations under Article 50(4) and (5), covering the labelling of deepfakes and AI-generated text published to inform the public on matters of public interest. On 8 July 2026, the Commission concluded that the Code adequately covers these obligations and facilitates their effective implementation.

The Article 50 Guidelines, published on 20 July 2026, provide practical guidance to assist providers, deployers, and competent authorities in ensuring compliance with the Article 50 transparency obligations. The Guidelines clarify key concepts, including what constitutes a directly interactive AI system (such as chatbots), the scope of synthetic content, and the treatment of deepfakes. They also address exceptions for AI systems that perform assistive functions for standard editing, and for AI systems authorised by law to detect, prevent, investigate, or prosecute criminal offences. The Guidelines complement the Transparency Code of Practice and explain how adherence to the Code may be used to demonstrate compliance with the EU AI Act’s requirements.

Under the Digital Omnibus for AI, providers of generative AI systems that were already placed on the market before 2 August 2026 have a four-month transitional period to comply with the Article 50(2) watermarking obligations, ending on 2 December 2026.

User transparency in Greece

In addition to the transparency requirements imposed directly by the AI Act and further elaborated in the European Commission’s soft-law ‘Guidelines on the transparency obligations of providers and deployers of AI systems’, the Greek AI Act Implementation Law establishes a registration obligation for AI systems in the public sector. Before deploying an AI system, public-sector bodies must register it in a centralised registry maintained by the Special Secretariat for Artificial Intelligence and Data Governance. Registration requires detailed information, including the system's purpose, public-interest objective, categories of data processed, technical characteristics and functionalities.

Fairness / unlawful bias

Fairness / unlawful bias in Greece

At its core, the EU AI Act is driven by the imperative to safeguard the fundamental rights of EU citizens. The rapid advancement of AI technologies has introduced significant benefits but also potential risks, such as biases in decision-making systems and privacy infringements. The AI Act aims to mitigate these risks by establishing clear rules that ensure AI systems respect the rights enshrined in the EU Charter of Fundamental Rights. This focus on human-centric AI seeks to enhance trust and acceptance among the public, thereby promoting wider adoption of AI technologies in a responsible manner.

Within the EU AI Act, non-discrimination and fairness are incorporated within the following:

Recital 27 includes seven principles for trustworthy AI including ensuring that AI systems are developed and used in a way that includes diverse actors and promotes equal access, gender equality, and cultural diversity, while avoiding discriminatory impacts and unfair biases that are prohibited by Union or national law.
Article 10 sets out data and data governance requirements for high-risk AI systems and includes a requirement to examine and assess possible bias in training, validation, and testing data sets.
Deployers are required to ensure that any input data is relevant and sufficiently representative in view of the intended purpose of the high-risk AI system (Article 26(4)).
Under Article 4a (introduced by the Digital Omnibus for AI), providers and deployers may exceptionally process special categories of personal data (such as data revealing racial or ethnic origin, political opinions, or religious beliefs) where strictly necessary for bias detection and correction. This legal basis is subject to strict safeguards, including pseudonymisation, access controls, deletion once bias correction is complete, and documentation in processing records.
Article 27 requires deployers of high-risk AI systems (where those deployers are public authorities or private entities providing public services) to conduct fundamental rights impact assessments before putting the system into use (see the High-risk AI section). These assessments must address, among other matters, the specific risks of harm to marginalised persons or vulnerable groups and the foreseeable impact on the categories of natural persons affected. The 19 May 2026 High-Risk Classification Guidelines provide further interpretive guidance on assessing when an AI system poses a significant risk to fundamental rights, including risks of discrimination, and clarify that AI systems used in contexts with heightened discrimination risks (such as employment, credit, and access to essential services) require careful assessment against the criteria in Article 6(3).
Article 5 prohibits certain AI practices that are inherently discriminatory, including AI systems that categorise natural persons based on biometric data to deduce or infer sensitive information about them (such as race, political opinions, trade union membership, religious beliefs, sex life, or sexual orientation), except where based on lawfully acquired datasets (see the Prohibited activities section).

The Framework Convention addresses the issue of bias (most notably in Articles 10 and 11 relating to ‘equality and non-discrimination') and highlights that AI has the potential to create and reinforce biases and that bias and discrimination by AI can cause manifest harm to individuals and to society. The Framework Convention encourages the development and sharing of strategies to counter these risks, including debiasing datasets in research and development and by the development of rules on data processing. This approach has the potential to turn software, algorithms, and data into an asset in fighting bias and discrimination in certain situations, and a force for equal rights and positive social change.

Fairness / unlawful bias in Greece

In the education sector, Greece has adopted specific rules addressing fairness and bias in AI use. The Decision identifies the prevention of algorithmic bias as a core objective and requires AI use in schools to respect principles of fairness and inclusion. Generative AI must be deployed in ways that ensure equal access, avoid algorithmic discrimination and stereotypes, and provide accessibility for students with disabilities or learning difficulties. The Decision prohibits fully automated decisions on student or teacher assessment, profiling and the use of AI-generated data for decisions affecting individuals’ personality, behaviour or rights. These protections are reinforced by requirements for human supervision, transparency, contestability of outputs and accessible complaint mechanisms.

Human oversight

Human oversight in Greece

Human oversight is crucial for preventing and mitigating risks associated with an AI system's operation. Providers must also ensure that operators are adequately trained to oversee the AI system, understand its functionalities, and respond appropriately to any issues. Effective human oversight enhances the safety and reliability of high-risk AI systems, ensuring they operate within acceptable parameters and can be controlled in case of unexpected behaviour or malfunctions.

Article 14 of the EU AI Act deals with human oversight, stating that providers must implement measures to ensure effective human oversight of high-risk AI systems. This involves designing the system with mechanisms that allow human operators to monitor, intervene, and deactivate the AI system if necessary. Providers of high-risk AI systems are required to ensure that systems falling under their responsibility are compliant with this requirement (Article 16(a)) and to include the human oversight measures within the ‘instructions for use’ for the high-risk AI system (Article 13(3)(d)).

In addition, deployers of high-risk AI systems are required to comply with the provider’s 'instructions for use' and to assign human oversight to persons that have the necessary competence, training, and authority as well as necessary support (Article 26(1) and (2)).

Finally, Recital 27 of the EU AI Act includes seven principles for trustworthy AI including ensuring that AI systems apply human agency and oversight. This means that AI systems are developed and used as a tool that serves people, respects human dignity and personal autonomy, and functions in a way that can be appropriately controlled and overseen by humans.

The Decision on the use of AI systems in secondary education contains several provisions relating to human oversight. AI systems may only support, and not replace, the role of educators, while all AI outputs must be supervised, reviewed and evaluated by appropriately trained educational staff. The Decision expressly prohibits fully automated decision-making for the evaluation of students or teachers, requires mechanisms for human oversight and intervention at every stage of system operation, and provides that AI outputs must remain contestable through human review and complaint procedures.
