Japan has become the latest country to launch an investigation into X's AI-powered service, Grok, following growing concerns about the platform's role in generating and distributing non-consensual sexualized imagery. The probe reflects broader regulatory scrutiny facing AI developers globally, as authorities grapple with content moderation challenges and the misuse of generative AI technology. This development underscores the regulatory landscape tightening around autonomous AI systems and their potential for harm, placing pressure on platforms to implement stronger safeguards and verification mechanisms. The case highlights the ongoing tension between innovation in AI services and the need for robust governance frameworks to protect user privacy and prevent abuse.
