MLex: The European Commission has released a template requiring AI developers to disclose training data under the EU AI Act. However, the scope of a key requirement, listing the top 10% of crawled domain names, remains unclear. Confusion centres on whether this should be per content type, known as modality, or in aggregate. How the size of the content should be accounted for is another point of confusion. Such vague wording could incentivise AI firms to limit disclosure. The Commission is preparing further guidance, but has so far declined to comment.
