Japan has joined the growing list of countries probing X over Elon Musk’s artificial intelligence service Grok and the chatbot’s role in creating and spreading sexualized images of people without their consent.

The Cabinet Office has asked the social media platform to improve safeguards and curb the output of sexually altered images by Grok, Economic Security Minister Kimi Onoda said.

Officials also submitted written questions about measures by X to prevent the creation of deepfakes and other images that violate people’s privacy, intellectual property and right to control the use of their likeness, she said.
