Tech titans Elon Musk and Sam Altman bickered over their relative trustworthiness on Tuesday, with each of their artificial intelligence platforms contributing to the feud.
The big picture: The two tech giants' acrimonious relationship has become increasingly public since Musk sued Altman for breaching OpenAI's founding mission last year.
Driving the news: Musk alleged that Apple engaged in an antitrust violation "that makes it impossible for any AI company besides OpenAI to reach #1 in the app store."
- "xAI will take immediate legal action," Musk wrote.
- "This is a remarkable claim given what I have heard alleged that Elon does to manipulate X to benefit himself and his own companies and harm his competitors and people he doesn't like," Altman responded.
The latest: An Apple spokesperson said in a Tuesday evening emailed statement that its App Store is designed to be fair and free of bias.
- "We feature thousands of apps through charts, algorithmic recommendations, and curated lists selected by experts using objective criteria," the spokesperson added.
Zoom out: Grok, powered by Musk's xAI, said Altman was right in the dispute.
- DeepSeek and Perplexity, other AI platforms, reached top App Store slots this year.
- "Musk has a history of directing X algorithm changes to boost his posts and favor his interests, per 2023 reports and ongoing probes," the Grok response said. "Hypocrisy noted."
- "good bot," ChatGPT's X account responded.
- Musk separately shared a screenshot asking ChatGPT 5 Pro whether he or Altman is more trustworthy. ChatGPT answered: "Elon Musk."
State of play: Altman and Musk have had repeated spats since Musk stepped down from OpenAI's board in 2018, as they both vie for leadership in artificial intelligence.
- Last year, Musk sued OpenAI, Altman and another founder claiming that they "deceived" Musk a decade ago. A federal judge in March denied Musk's request to pause OpenAI's transition into a for-profit model, but agreed to a fast-track trial this in the fall of this year.
- In February, a feud between the two escalated as they both tried to wield influence in President Trump's AI plan. Musk was reportedly interested in buying OpenAI for $97.4 billion — which Altman refused.
- "I don't think about him that much," Altman said of Musk in a Friday CNBC "Squak Box" interview.
