DUBLIN (Reuters) - Google's lead EU privacy regulator opened an inquiry on Thursday into whether the search engine giant adequately protected European Union users' personal data before using it to help develop its foundational AI Model.

Ireland's Data Protection Commission (DPC), the lead EU regulator for most of the top U.S. internet firms due to the location of their EU operations in Ireland, said the probe concerned the Alphabet Inc unit's Pathways Language Model 2 (PaLM 2).
