- The DecoderOpenAI plans to train models on Daybreak Blue cybersecurity session data that was previously off-limits
Starting November 29, OpenAI will use data from Daybreak Blue sessions to train its models, even when users have turned off training. After backlash, a follow-up email promised a separate opt-out. The move revives concerns from the dispute with mathematicians who suspected OpenAI used their unpublished research for training without consent.
