Elon Musk said Tuesday his social media platform X is working to fix its AI chatbot, Grok, after it sided with rival tech chief and OpenAI CEO Sam Altman in an ongoing dispute with Musk, who threatened to sue Apple on Monday night over allegations it favors OpenAI in its app store.

Musk, who has been at loggerheads with Altman since their fallout after co-founding OpenAI, reacted strongly to Grok's response. He criticized the platform for allowing false defamatory statements about him. The incident highlights the challenge of maintaining neutrality in AI chatbots like Grok.

The account was quickly taken down with a vague notice about rule violations, but no official reason was given. When Grok reappeared, it offered mixed explanations for the suspension, sparking widespread confusion.
