AI Act training-content summary

Under Article 53(1)(d) of the AI Act, providers of general-purpose AI models must publish a sufficiently detailed summary of the content used for training, using the template provided by the AI Office.

The obligation applies from 2 August 2025 (Article 113 of Regulation (EU) 2024/1689). The Commission published the template in July 2025.

Arieta Data publishes a ready-made description of its corpus that buyers can paste into the relevant sections of their summary.
