OpenAI Says Siri Integration of ChatGPT Underperformed
Developing
In Short: OpenAI claims the Siri integration of ChatGPT was 'persistently underperforming,' according to court documents.

OpenAI reported in court documents that its integration of ChatGPT into Siri was 'persistently underperforming,' leading to a reassessment of user forecasts.
By January 2025, OpenAI noted the integration was off to a slow start, prompting a reduction in the expected number of incremental logged-in weekly active users.
In a later filing, OpenAI reiterated that the Siri integration was underperforming, leading to a redacted conversation between Apple and OpenAI in March 2026.
Apple had planned to integrate one provider and then add more, as it stated publicly when announcing the feature.
Dr. Tucker's analysis found minimal usage of Apple's AI feature, consistent with OpenAI's view.
OpenAI added ChatGPT to Siri in December 2024, but users had to go through a multistep opt-in process, adding friction.
OpenAI requested a two-year exclusivity period from Apple, which was denied.
OpenAI disputes many of the claims in the lawsuit filed by Elon Musk's company SpaceXAI (xAI at the time).
Musk alleged an exclusive deal between Apple and OpenAI harmed xAI's growth and customer acquisition.
OpenAI argues that even if there were an exclusive deal, the ChatGPT Siri integration did not attract many new users, thus causing minimal harm.
What this adds
The court documents provide new details on the performance and negotiations between Apple and OpenAI, shedding light on the integration challenges.
What's still developing
- 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.
- 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.
