The DPC said it will review whether Google complied with obligations under the EU's General Data Protection Regulation, or GDPR, before processing personal data of EU users to help develop its foundational AI model, Pathways Language Model 2 (PaLM 2).

"This statutory inquiry forms part of the wider efforts of the DPC, working in conjunction with its EU/EEA peer regulators, in regulating the processing of the personal data of EU/EEA data subjects in the development of AI models and systems," said DPC in a press release on Thursday.

Last week, the Irish data regulator said it ended court proceedings against X after the social media platform agreed to limit its use of personal data collected from EU users to train its AI model Grok on a permanent basis.
