Google is under investigation by Europe’s privacy watchdog over its processing of personal data in the development of one of its artificial intelligence models, as regulators ramp up their scrutiny of Big Tech’s AI ambitions.

Ireland’s Data Protection Commission, which is responsible for enforcing the EU’s General Data Protection Regulation, said it had launched a statutory inquiry into the tech giant’s Pathways Language Model 2, or PaLM 2.

PaLM 2 was launched in May 2023 and predates Google’s latest Gemini models, which power its AI products. Gemini, which was launched in December of the same year, is now the core model behind its text and image-generation offering.
