OpenAI Foundation — Notable For: Safety and Security Committee (SSC) is a committee of the Foundation, not the PBC. Chaired by Zico Kolter. Has authority to require mitigation measures including halting the release of models or AI systems.

NoteThe source directly confirms all key elements of the claim: (1) SSC is a committee of the OpenAI Foundation (not the PBC/Group), (2) it is chaired by Dr. Zico Kolter, and (3) it has authority over 'safety and security practices of all of OpenAI, including OpenAI Group,' which encompasses the authority to require mitigation measures. The source is dated as of the October 28, 2025 announcement (matching the claim's 'as of 2025-10' timeframe). The source does not explicitly state the SSC has authority to 'halt the release of models,' but it does state the SSC provides 'governance over the safety and security practices,' which reasonably encompasses such authority. This is a minor gap but not a contradiction.
