The UK government has launched unprecedented regulatory action against Elon Musk’s X platform, with Ofcom beginning a formal investigation into the AI chatbot Grok for generating illegal sexualized deepfakes. Prime Minister Keir Starmer warned X could lose its “right to self-regulate” under the Online Safety Act. Despite these concerns, the Pentagon is moving forward with integrating Grok AI into its network this month. Separately, Apple is partnering with Google to integrate Gemini AI into its next-generation Siri assistant, a collaboration confirmed on January 12, 2026, to enhance Siri's capabilities. In other AI developments, Instagram is reportedly developing new features, including AI-powered transitions for Stories and AI voice filters for direct messages.
