At the Dublin International AI Summit, Anthropic's international business lead said open-weight AI models are riskier than Anthropic's own models and that he cannot guarantee their safety. He cited the company's experience securing its products, warned that small AI models could soon drive new botnets, and called for slowing AI development until international standards and unified evaluation mechanisms are established. He also said continued investment in frontier models is worthwhile, noting Claude Opus 5.5 is 40% cheaper than earlier versions.
