OpenAI: Apple's integration of ChatGPT falls short of expectations, subscription conversion below forecasts

BlockBeats news, September 24 — The UK's Financial Times, citing newly released court documents, reported that after Apple integrated ChatGPT into Apple Intelligence, OpenAI found that new weekly active users fell short of expectations and began lowering its growth forecasts. By the summer of 2025, OpenAI internally regarded the integration as "clearly underwhelming."

The documents show that ChatGPT is disabled by default in Apple Intelligence, requiring users to actively enable it, which may have limited its actual usage rate. Although users can invoke ChatGPT through Siri and system writing tools, Apple controls the entry point to AI features, the method of invocation, and the choice of subsequent models.

OpenAI had previously hoped to leverage the iPhone's massive user base to expand ChatGPT's reach and further drive user conversion into paid subscribers, but actual subscription conversion also fell short of expectations. The documents did not disclose specific new user or subscriber numbers.

Apple this year chose Google Gemini as the model foundation for the new version of Siri AI, further highlighting Apple's control over the core AI entry point. The disclosures come from court documents related to litigation between Apple and OpenAI, reflecting OpenAI's position in the litigation, not publicly released operating data from the two companies.
