OpenAI filed court documents stating its integration of ChatGPT into Apple's Siri was "persistently underperforming," despite a December 2024 launch. The filing, part of a legal battle with Elon Musk's SpaceXAI, reveals the partnership started slowly, leading OpenAI to cut its forecast for new weekly active users. By early 2025, the integration was deemed "dramatically underperforming," with minimal user adoption.

The agreement was non-exclusive, allowing Apple to partner with other providers like Google, whose Gemini powers newer Apple models. OpenAI's filing refutes Musk's allegations of an exclusive deal harming x AI, arguing the integration caused negligible foreclosure. Expert analysis by Dr. Catherine Tucker supports this, finding minimal impact.

Recently, Musk's companies dropped claims against Apple, leaving OpenAI as the sole defendant ahead of a January 2027 trial.
