Deployers must use the provider's transparency information in their data protection impact assessment
EU AI Act · Article 26(9)
Where a deployer of a high-risk AI system is required to carry out a data protection impact assessment under Article 35 of the GDPR or Article 27 of the Law Enforcement Directive, it must draw on the information the provider supplied under Article 13, such as the intended purpose, performance, limitations and human-oversight measures, when producing that assessment.
