AI overview

OpenAI announced on November 29 that it will use Daybreak Blue cybersecurity session data to train its models, reversing a previous policy that excluded such data even when model improvement settings were disabled. The change affects Trusted Access program members, who were notified via email. Security researchers have expressed concern that this may repeat the issues of the "Buckmaster-Alpöge" case, though OpenAI has pledged to provide a separate opt-out option.

    Report first recorded Nov 1, 01:19

    OpenAI will use Daybreak Blue cybersecurity session data to train its models starting November 29, reversing a previous policy that excluded this data even when users opted out of training. The change follows backlash from researchers, who worry it could repeat the controversy of the Buckmaster-Alpöge case, in which mathematicians suspected their inputs were used without consent. OpenAI has promised a separate opt-out for this data type.
