The Italian Data Protection Authority (Garante) announced on December 20 that it has fined ChatGPT manufacturer OpenAI 15 million euros (about $15.58 million) after concluding its investigation into the use of personal data by generative artificial intelligence applications. Garante said it found that OpenAI processed users' personal data in order to train ChatGPT without sufficient legal basis, in violation of the principle of transparency and related information obligations to users.
