OpenAI opt-out skips personal Daybreak Blue sessions

From November 29, OpenAI may use content from Daybreak Blue sessions on personal accounts to improve its models, even with the model-improvement setting off, the company told users by email. If you rely on that setting to keep your work out of training, it won’t cover those sessions after that date.

The user who posted the email says that, as far as they know, Daybreak Blue can’t be switched on or off in the Codex CLI on personal accounts.
