I like open-weight models. I think Jensen Huang’s argument — that open weights let more eyes find more flaws faster — is broadly correct as a security philosophy, and I’ve made versions of that argument in print before this week. I still believe it. I just don’t think this week is the evidence for it that the industry’s letter wants it to be. Meta, Microsoft, OpenAI and others signed a letter defending open-weight models against “premature restrictions,” timed to Huang’s first-ever post on X making the eyes-on-the-code case.
