Understanding the EU AI Act

The regulatory framework takes a risk-based approach to AI governance.

Framework Overview

The EU AI Act establishes a comprehensive regulatory framework that applies to AI systems placed on or used in the EU market. The regulation extends extraterritorially to providers outside the EU if their system outputs are used within the Union. This affects multiple parties in the AI supply chain, including providers, deployers, importers, and distributors.

The framework employs a risk-based classification approach, dividing AI systems into four distinct categories:

• Unacceptable Risk: Prohibited AI practices that are banned outright in the EU
• High Risk: Systems subject to strict requirements and conformity assessment procedures
• Limited Risk: AI applications requiring transparency obligations only
• Minimal Risk: Systems with no mandatory requirements, though voluntary codes of practice are encouraged

Key Implementation Timeline

The regulation follows a phased implementation schedule with critical deadlines:

Risk Categories Deep Dive

Prohibited AI Practices

Certain AI systems are completely banned in the European Union due to their potential for harm to fundamental rights and human dignity. Organizations must identify and discontinue any such systems by February 2025.

Subliminal Manipulation: AI systems that deploy techniques designed to distort behavior in ways that cause psychological or physical harm are prohibited. This includes manipulative advertising and hidden persuasion tactics that operate below the threshold of conscious awareness.

Exploitation of Vulnerabilities: AI systems that exploit vulnerabilities related to age, disability, or socioeconomic situation are banned. Examples include predatory marketing targeting elderly individuals or systems designed to exploit financial distress.

Social Scoring by Public Authorities: The classification of individuals based on their social behavior by public authorities is prohibited. Note that private credit scoring is not banned but may qualify as high-risk depending on implementation.

Real-Time Biometric Identification in Public Spaces: Live facial recognition in publicly accessible spaces is generally prohibited, with narrow exceptions for specific law enforcement scenarios requiring judicial authorization.

Emotion Recognition in Workplace and Education: AI systems that infer emotions in workplace or educational settings are prohibited, except when deployed for legitimate medical or safety purposes.

Biometric Categorization: Systems that infer sensitive attributes such as race, political opinions, religious beliefs, or sexual orientation from biometric data are banned.

Facial Recognition Database Scraping: The practice of scraping facial images from the internet or CCTV footage to create facial recognition databases (similar to Clearview AI-style systems) is prohibited.

High-Risk AI Systems

High-risk systems face the strictest regulatory requirements. These fall into two categories:

Annex I: Safety Components: AI systems that function as safety components in products already covered by EU safety legislation. This includes machinery, medical devices, toys, and vehicles. Systems in this category that require third-party conformity assessment under existing product safety laws face enhanced scrutiny.

Annex III: Standalone High-Risk Systems: AI systems deployed in specific use cases deemed to pose significant risks to health, safety, or fundamental rights:

The key test for high-risk classification is whether the system poses significant risks to health, safety, or fundamental rights. Notably, AI systems performing purely procedural tasks may not qualify as high-risk even if deployed in these domains.

Limited and Minimal Risk Systems

Limited Risk Systems: These AI applications face transparency obligations only. Organizations must ensure users are aware they are interacting with AI systems:

• Chatbots: Must disclose that users are interacting with an AI system
• Emotion Recognition: Must inform subjects when emotion inference is deployed (where permitted)
• Biometric Categorization: Must inform subjects when biometric categorization occurs (where permitted)
• Deepfakes: Must clearly label synthetic content as artificially generated
• AI-Generated Content: Must label AI-generated content when used in matters of public interest

Minimal Risk Systems: The vast majority of AI applications fall into this category, including spam filters, game AI, and inventory optimization systems. These face no mandatory requirements, though voluntary codes of conduct are encouraged to promote responsible development.

General Purpose AI (GPAI) Provisions

The Act includes specific provisions for foundation models and general-purpose AI systems.

GPAI Classification

General Purpose AI models are defined as AI models trained with significant generality that display significant capabilities across a wide range of tasks. The key criteria include:

• Broad Training Data: Trained on large-scale, diverse datasets
• General Purpose: Capable of performing many different tasks rather than optimized for a single use case
• Integrability: Can be integrated into a variety of downstream systems and applications

GPAI models are further classified into two tiers:

Standard GPAI Models

Models below the systemic risk threshold face baseline requirements:

1. Technical Documentation: Comprehensive documentation of model architecture, training process, and capabilities
2. EU Copyright Law Compliance: Demonstrate compliance with EU copyright law and put in place policies respecting opt-outs from copyright holders
3. Training Content Summary: Provide a detailed summary of the content used for model training

Systemic Risk GPAI Models

Models exceeding 10²⁵ FLOPs of computing power used for training, or otherwise designated by the Commission, face additional obligations:

• Model Evaluation and Testing: Conduct standardized evaluations and adversarial testing
• Serious Incident Assessment: Assess and mitigate risks of serious incidents, including tracking and reporting
• Adequate Cybersecurity Protection: Implement robust security measures to protect the model and its infrastructure
• Energy Consumption Reporting: Report on the energy consumption of model training and operation

Systemic risk designation considers high-impact capabilities, reach to large numbers of users, and potential for large-scale harm.

GPAI Provider Obligations

Obligations for All GPAI Providers

Documentation Requirements: Providers must document the training process, testing methodologies, and comprehensive information about model capabilities and limitations.

Copyright Compliance: Organizations must identify and comply with EU copyright law, provide a detailed summary of training content, and respect requests from copyright holders to opt out their content from training data.

Downstream Information: GPAI providers must supply sufficient information to downstream providers to enable them to comply with high-risk requirements if the GPAI model is integrated into a high-risk system.

Additional Requirements for Systemic Risk GPAI

Evaluation and Testing: Conduct model evaluations using standardized protocols, perform adversarial testing (red teaming) to identify systemic risks, and assess dangerous capabilities that could emerge from the model.

Risk Mitigation: Assess and mitigate risks of serious incidents, establish processes to track incidents, and report serious incidents to regulatory authorities.

Cybersecurity: Implement adequate protection for the model itself and secure the infrastructure used for training, deployment, and access.

Transparency: Report energy consumption for model training and operation, and publish information about model capabilities and limitations.
