Bitcoin Red Team co-founder Rob Hamilton said August 9 that he had begun integrating OpenAI’s trust cyber program into the group’s security work before access was restricted during further analysis of a codebase already under responsible disclosure. The setback pushed the team back toward Chinese open-weight AI models to continue Bitcoin security testing.
Yesterday I began fully integrating the @OpenAI trust cyber program into my Bitcoin Red Team efforts.
This morning I woke up to see this.
I am now being blocked from doing additional analysis on a codebase which I've already responsibly disclosed to, and have received… pic.twitter.com/Ain5RbOBDN

Hamilton’s Red Team has been using models including Kimi K3 to examine Bitcoin-related software for vulnerabilities, with earlier work uncovering multiple serious issues across the ecosystem. He has argued that open-weight models materially changed what small security teams can accomplish, making unrestricted AI access increasingly important for offensive code review and vulnerability discovery.
Hamilton said the restriction prevents additional analysis even after his team responsibly disclosed the relevant issue and received acknowledgment. The immediate question is whether security researchers can maintain effective white-hat testing when access to frontier AI tools depends on platform restrictions, or whether open models become the more dependable infrastructure for Bitcoin red teaming.
