The correct answer isA. Only GPAI modelswith systemic riskmustpublish a detailed summary of training datato meet transparency and accountability standards under the EU AI Act.

From the AI Governance in Practice Report 2025 (EU AI Act Section):

“For GPAI systems with systemic risk, providers must publish sufficiently detailed summaries of the content used to train the model.”

Also, the AIGP ILT Guide confirms:

“The obligation to disclose summaries of training data applies only to systemic-risk GPAI models, not all general-purpose models or high-risk systems.”

This unique requirement is part of the Act’s effort to increasetransparency and auditabilityfor powerful foundational models.
