It was previously reported that OpenAI was deeply dissatisfied with its partnership with Apple over ChatGPT integration, with the company even considering legal action. Now, details of those concerns have been formally documented in a filing related to the antitrust lawsuit involving SpaceXAI.
Apple and OpenAI became involved in the antitrust case following allegations made by Elon Musk. Although Apple has since been removed from the lawsuit, the legal dispute itself remains ongoing.
OpenAI did not have access to the details of the settlement reached between Apple and SpaceXAI. However, in its latest filing, the company has outlined why it believes the lawsuit should be dismissed. The document also provides a detailed account of the unusual legal dispute and reveals how disappointed OpenAI was with the results of its Apple partnership.
Reports of OpenAI's frustration with the deal had surfaced previously, including claims that the company had considered suing Apple. The latest filing now provides further confirmation of those concerns.
According to Sections D and F of the filing, OpenAI argues that Apple's implementation of ChatGPT within iOS and Siri was problematic from the outset. Because the integration required users to opt in and was limited in how it could be accessed, users were more likely to launch the standalone ChatGPT app rather than interact with the service through Siri.
A Partnership That Fell Short
The feature launched in December 2024, but by January 2025, OpenAI had already determined that its initial usage forecasts needed to be significantly reduced. By March 2026, the company was reportedly describing the integration as "persistently underperforming."
During the same period, Apple introduced its own Apple Foundation Models, which were developed using a Gemini Frontier model for distillation. While Apple and OpenAI did not have an exclusivity agreement, Apple also did not introduce additional Siri extensions that could have expanded the partnership.
The agreement also limited OpenAI's ability to gain additional benefits from ChatGPT usage through Siri. Since user data from the integration was not collected or used for training, the main potential advantage for OpenAI was the possibility of attracting new users and converting them into paid subscribers.
