David Robinson, who was responsible for the 'safety transparency' function within the OpenAI Safety Systems team, has departed. According to BI, Robinson himself has not yet publicly explained the reason for his departure, and OpenAI has not announced a successor.
This role does not directly train models, nor does it directly do red-teaming, but it is responsible for organizing internal technical findings, risk judgments, and deployment decisions into public materials that outsiders can understand. In Robinson's own words, the work he did was to help outsiders understand and trust the technical work OpenAI carries out to keep systems safe.
Safety transparency work belongs to the Trustworthy AI team within Safety Systems, and its outputs include system cards, the Deployment Safety Hub, safety research blogs, and public governance documents. Almost every time OpenAI releases an important model, Robinson and the team he led would write a system card for the model—that is, a risk disclosure document.
