The EU law requires developers of “general purpose AI” (GPAI) models to keep track of and disclose what content is used in training. It further states that “any use of copyright protected content requires the authorization of the [rights holder] concerned, unless relevant copyright exceptions and limitations apply.” “Crucially, this appears to apply even if the training was carried out in another more lenient jurisdiction,” said Jonathan Coote, a music and AI lawyer at UK law firm Bray & Krais.
