After Cyber Incident, Mitchell Reaffirms Open Models Are Key to Defense

A recent cybersecurity incident has brought the value of open models for security defense back into the spotlight. Margaret Mitchell took the opportunity to reaffirm her consistent stance: in the face of malicious AI use, open sharing is not the root cause, but rather the key to building societal defense capabilities.

The Necessity of Open Models for Defense

Mitchell argues that regulation alone cannot stop malicious actors from sharing dangerous methods in the dark or secretly developing high-risk models. Even without open-source models, malicious use will not disappear. Closing open-source models would weaken public defense and concentrate power among a few Silicon Valley companies. She emphasizes that individuals and organizations should not be forced to rely on a single commercial company for self-defense, and that accessible defense resources must be provided.

Clarifying Open-Source Misconceptions and Maintenance Responsibilities

In open-source governance, Mitchell points out common misconceptions. She clarifies that the core of openness is code visibility, not allowing anyone to push code directly to production. Standard open-source projects allow users to submit code, but this only enters a review process involving automated checks and manual safety verification.

Furthermore, she distinguishes between code submission permissions and project maintenance responsibilities. If an open-source project relies solely on individual developers or students, it is prone to security issues. Therefore, the industry urgently needs true open-source security companies that employ full-time security experts to maintain code quality and update safety guardrails, providing long-term, reliable security.
