During a recent online clash with Sam Altman, the CEO of OpenAI, Elon Musk experienced an unexpected twist when his own AI chatbot, Grok, publicly sided with Altman. The confrontation began after Musk accused Apple of unfairly promoting OpenAI’s ChatGPT in the App Store.

The tournament saw models from Anthropic, Google, xAI and DeepSeek compete against each other to be crowned the top AI chess player.

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.
