The European Union's AI Act, formally Regulation (EU) 2024/1689, introduces a risk-based regulatory framework for AI systems, focusing on mitigating risks associated with their deployment in critical sectors like healthcare, transportation, and law enforcement. The Act categorizes AI systems by their potential for harm, imposing stringent oversight on high-risk systems to ensure public safety and the protection of fundamental rights. This categorization is central to understanding the distinctions between High-Risk AI Systems and General-Purpose AI - two distinct concepts under the AIA.

Classification and Risk Level

High-Risk AI Systems are explicitly identified due to their potential to cause substantial impact on public health, safety, and fundamental rights. This classification hinges on the intended use of these systems, especially if they function as critical safety components in products or are standalone products requiring third-party conformity assessments (Article 6 AIA). AI systems utilized in critical sectors—such as biometric identification, critical infrastructure management, education, employment, and law enforcement—fall under this high-risk category. The stringent classification is designed to address the potential consequences of these systems failing or being misused, which could lead to significant harm.

On the other hand, General-Purpose AI Systems are not inherently categorized as high-risk. These systems are versatile and designed to perform a broad range of tasks across various applications. While not specifically restricted to high-risk scenarios, General-Purpose AI can become part of high-risk systems depending on how they are used (Recital 97 AIA). This adaptability means that while these systems might not initially be subject to the same stringent regulations as high-risk AI, they may still need to comply with higher regulatory standards when integrated into high-risk environments.

Intended Use

The deployment context of AI systems plays a crucial role in determining their regulatory classification. High-Risk AI Systems are typically employed in sectors where failure or misuse could result in significant harm, such as healthcare, transportation, and public safety (Article 3 AIA). In these areas, the stakes are particularly high, necessitating robust regulatory frameworks to mitigate potential risks.

In contrast, General-Purpose AI Systems are designed with adaptability in mind, allowing them to be used across a variety of contexts. Although they are not restricted to high-risk applications, when these systems are incorporated into high-risk environments, they must adhere to the same stringent requirements as high-risk AI systems (Recital 97 AIA). This ensures that their deployment does not inadvertently introduce significant risks.

Compliance Requirements

Given their potential impact, High-Risk AI Systems are subject to rigorous compliance requirements to ensure their safety, transparency, and reliability. These include the establishment of documented risk management systems (Article 9 AIA), ensuring transparency and enabling effective human oversight (Article 13 and 14, AIA), maintaining high-quality datasets (Recitals 66 and 71 AIA), and undergoing comprehensive conformity assessments before being placed on the market (Recital 123 AIA). These measures are designed to build public trust and mitigate the risks associated with deploying these high-risk technologies.

General-Purpose AI Systems, while not subject to the same stringent requirements, must still ensure compliance when integrated into high-risk systems. This involves close cooperation with providers of high-risk AI systems to align on compliance obligations and share necessary information to meet regulatory standards (Recital 85 AIA). The flexibility afforded to general-purpose AI allows for broad application, but this adaptability comes with the responsibility to meet higher regulatory standards when required.

Regulatory Obligations

To mitigate risks, High-Risk AI Systems are obligated to meet specific criteria concerning accuracy, robustness, cybersecurity, and transparency (Article 15 AIA). These obligations are critical to ensuring that these systems function reliably and safely in environments where their failure could have severe consequences.

In comparison, General-Purpose AI Systems face less stringent obligations unless they are integrated into high-risk systems. When they are part of such systems, they must comply with the high-risk system's regulatory requirements, ensuring that they do not compromise the overall safety and reliability of the technology (Recital 85 AIA).

Conclusion

The distinction between High-Risk AI Systems and General-Purpose AI under Regulation (EU) 2024/1689 reflects the EU's commitment to safeguarding public interests while fostering innovation in AI. High-risk systems are rigorously regulated to protect against potential harms, ensuring their deployment in critical sectors is safe and trustworthy. Meanwhile, general-purpose AI systems maintain their versatility, with the understanding that their integration into high-risk environments demands adherence to stringent compliance measures.
