Daybreak users post an OpenAI email with November training and API dates

On Oct. 30, 2026, Daybreak users posted an OpenAI email saying that from Nov. 29 the company may use personal-account Daybreak Blue sessions to improve models even when Improve the model for everyone is off. Copies that describe two changes also say individual API access to Daybreak Blue ends Nov. 20, while Codex access through a ChatGPT sign-in continues, and a follow-up quoted from a recipient promises a separate opt-out except for interactions flagged for safety review. OpenAI's data-controls page, read Nov. 1, still states the training exception and still gives no start date, opt-out, or API cutoff. The email says business and enterprise customers are not affected.
