OpenAI saw disappointing results working with Apple to integrate ChatGPT in Siri, according to court documents filed [PDF] in its ongoing legal fight with Elon Musk’s company SpaceXAI (xAI at the time the lawsuit was filed).
Apple added ChatGPT to ?Siri? in December 2024, but users had to go through a multistep opt-in process, which added a layer of friction. By January 2025, OpenAI said the integration was “off to a slow start” and the company cut its forecast for the number of incremental logged-in weekly active users that it expected to get from the partnership.
Much of the filing is redacted, but OpenAI said that by the time Musk’s companies filed an antitrust lawsuit against Apple and OpenAI, “it was clear that Apple’s integration of ChatGPT was dramatically underperforming.” In a later section of the filing, OpenAI said again that the Apple integration was “persistently underperforming,” leading to a March 2026 conversation between Apple and OpenAI that is redacted.
OpenAI asked Apple for a two-year exclusivity period, but Apple refused. The agreement between the two companies explicitly said the deal was non-exclusive and Apple had the right to “integrate products or services that provide the same or similar functionality as [ChatGPT].” Apple told OpenAI that it planned to integrate one provider and then add more, and it made similar statements publicly when announcing the feature. Apple also signed a deal with Google, and Apple’s newest models are based on Gemini.
OpenAI’s filing disputes many of the claims in the xAI lawsuit. Musk alleged OpenAI and Apple had an exclusive deal and that the agreement harmed xAI’s growth and customer acquisition. OpenAI says the contract proves there was no exclusive deal, and even if there were, xAI can’t prove harm because the ChatGPT ?Siri? integration just didn’t draw many new ChatGPT users.
Even if the Court assumes that Apple users who elect to use ChatGPT through Apple Intelligence are foreclosed from OpenAI’s rivals (which they are not), the amount of foreclosure caused by the Agreement is indisputably de minimis. While Plaintiffs’ experts declined to calculate foreclosure shares, OpenAI’s expert, Dr. Catherine Tucker, calculated the share of GenAI consumers who accessed ChatGPT through Apple Intelligence across multiple metrics using the same data and market definition relied upon by Plaintiffs’ experts. On these assumptions, Dr. Tucker found foreclosure shares of [REDACTED] across all metrics, consistent with OpenAI’s internal view that Apple Intelligence saw minimal usage.
Musk’s companies dropped their claims against Apple earlier this month, leaving OpenAI as the sole defendant in the lawsuit. OpenAI’s filing asks the court to toss out xAI’s claims prior to the trial planned for January 2027.Tags: ChatGPT, OpenAI, SiriThis article, “ChatGPT in Siri ‘Persistently Underperforming,’ Says OpenAI” first appeared on MacRumors.comDiscuss this article in our forums
