Elon Musk is suing Apple and OpenAI over a deal the companies struck to bring ChatGPT to iPhone users, according to a lawsuit filed Monday with the US District Court for the Northern District of Texas, in Fort Worth. 

The lawsuit's main complaint is that Apple doesn't allow iPhone owners to use any other kind of chatbot, like xAI's Grok. Because of this, consumers are locked into using ChatGPT, which gives OpenAI the "benefits from billions of user prompts" that helps the company improve its AI and scale its business. The lawsuit also alleges that Apple manipulated rankings in its App Stores to deprioritize non-OpenAI chatbots, something Apple has previously denied.

Apple and xAI did not respond to a request for comment by the time of publication. An OpenAI spokesperson said, "This latest filing is consistent with Mr Musk's ongoing pattern of harassment."

The lawsuit was filed by xAI, the company behind the Grok chatbot, and its parent company xAI Corp., which Musk founded and includes social media platform X/Twitter.
