**[OpenAI: Apple's Integration of ChatGPT Falls Short of Expectations, Subscription Conversion Below Forecast]** BlockBeats News, September 24 — The Financial Times reported, citing the latest court documents, that after Apple integrated ChatGPT into Apple Intelligence, OpenAI found that the increase in weekly active users was below expectations and began lowering growth forecasts. By the summer of 2025, OpenAI internally had already deemed this integration "clearly below expectations." The documents reveal that ChatGPT is set to default off within Apple Intelligence, requiring users to actively enable it, which may limit its actual usage rate. Although users can access ChatGPT via Siri and system writing tools, Apple controls the entry points, invocation methods, and subsequent model selection for AI functionalities. OpenAI had previously hoped to leverage the vast user base of iPhone to expand ChatGPT's reach and further drive users to convert into paid subscribers, but actual subscription conversions also fell short of expectations. The documents did not disclose specific figures for new users or subscription numbers. This year, Apple chose Google Gemini as the foundational model for the new version of Siri AI, further highlighting Apple's control over core AI entry points. The related disclosures come from court documents tied to litigation between Apple and OpenAI, reflecting OpenAI's stance in the lawsuit rather than publicly released operational data from the two companies.
