Italian privacy regulator Garante said on Friday that it decided to fine OpenAI of 15 million euros (15.58 million dollars) after completing an investigation into ChatGPT developer OpenAI's use of personal data.
Garante is one of the EU's most active regulators in evaluating whether AI platforms comply with EU data privacy regulations.
Garante said it found that OpenAI's processing of users' personal data “was to train ChatGPT without sufficient legal basis, in violation of the principle of transparency and the relevant information obligations of users.”
There was no immediate comment from OpenAI. It has previously said it believes its practices are in line with EU privacy laws.
Last year, Italian regulators briefly banned the use of ChatGPT in Italy for allegedly violating EU privacy rules.
The service was reactivated after Microsoft-supported OpenAI resolved issues such as users' right to refuse consent to the use of personal data training algorithms.
