The "Methodology for Classifying General-Purpose AI Models with Systemic Risks" under the European Union Artificial Intelligence Act (EU AI Act) offers a comprehensive framework to address the challenges posed by rapidly advancing general-purpose AI (GPAI) technologies. These models demonstrate wide-ranging capabilities across domains and hold transformative potential for innovation, but their scale, functionality, and societal influence also pose systemic risks. The document establishes a structured methodology to identify, classify, and mitigate these risks while ensuring AI models are deployed ethically, responsibly, and sustainably.
