Anthropic CEO Dario Amodei says the company is not advocating for a ban on open-weight AI models after facing criticism for not signing a recent industry letter supporting them. In a post shared Sunday, Amodei states that Anthropic has “never advocated for a ban on open-weights models,” and argues that open-weight models without dangerous capabilities can serve as a public good. The comments come amid speculation that Anthropic’s silence and position on safety issues may have been aimed at limiting open-weight releases.
Amodei also responds to broader concerns about model safety and effectiveness, saying he does not believe a ban would be an effective approach to improving AI safety. Separate reporting highlights that his remarks include additional caution about risk, including concerns related to China’s expanding AI capabilities. Across outlets, the core message remains that Anthropic does not support banning open-weight models, while emphasizing that safety considerations still play a role in how such models should be handled.
