Tech billionaire Elon Musk has dropped his lawsuit against Apple over claims that the iPhone maker unfairly favoured OpenAI's ChatGPT over rival chatbots.
Musk sued Apple and ChatGPT developer OpenAI just over a year ago, alleging that Apple was hindering competitors such as his Grok chatbot to give ChatGPT an advantage.
Court filings on Monday said the claims against Apple had been resolved, without providing details on how. Musk's lawsuit against OpenAI, however, remains in place.
Musk was an early investor in OpenAI and has been involved in a long-running dispute with its chief executive, Sam Altman.
Among other things, Musk accused Altman of unlawfully turning OpenAI, which was originally founded as a non-profit organization, into a profit-driven company and benefiting from the change. A California jury ruled against Musk in that case.
Musk's allegations against Apple centred on a partnership with OpenAI announced in 2024. Under the arrangement, users of iPhones and other Apple devices can send queries that Apple's Siri voice assistant cannot answer to ChatGPT.
Shortly before Musk's decision to drop the case against Apple became known, the company launched a new version of Siri in the United States featuring artificial intelligence upgrades.
The new Siri was developed by Apple, while Google's Gemini AI model provides the foundation for some of its features.
In his lawsuit, Musk argued that Apple held a monopoly in the US smartphone market with a 65% share, while OpenAI controlled 80% of the AI chatbot market.
Those claims formed the basis of his allegations of anti-competitive behaviour. Musk had sought damages as well as an end to the Apple-OpenAI partnership.
At the time the lawsuit was filed, Grok had come under fire after producing anti-Semitic remarks and praising Adolf Hitler. Musk's AI company xAI blamed the incident on a programming error.
Musk has since incorporated xAI into his space company SpaceX.
