【Anthropic CEO published a lengthy response to safety concerns, saying it must remain at the technological frontier】Anthropic recently submitted a AI safety bill draft to U.S. lawmakers, prompting questions from U.S.AI safety advocates. The draft sets a high threshold for the government to urgently halt dangerous models: risks must involve biological weapons, cyberattacks, or AI loss of control, and could result in more than 50 deaths or serious injuries, or more than 1000000000 USD in losses; some provisions may also limit state governments' regulatory authority.AI Safety organization Encode AI strategy lead Nathan Calvin subsequently reviewed Anthropic decisions made over the past 1 years. This year,February the company revised its previously stringent safety policy: it had previously committed to pausing training or releases if safety measures failed to keep pace with model capabilities, but the new policy no longer requires the company to halt research and development on its own at higher-risk stages, citing the possibility that competitors could overtake it. During the same period, the company invested heavily in computing power, built a chip team, and assigned Claude more AI research and development tasks.Anthropic CEO Dario Amodei posted a lengthy rebuttal on X. He acknowledged that the company had made some mistakes, but maintained that competing for the most advanced AI capabilities does not conflict with its safety mission. He said the company pursues a race to the top: only by remaining at the technological frontier can it push the industry to raise safety standards. He listed safety decisions that had imposed commercial costs on the company, including restricting access to Mythos-class models for several months and strictly limiting biology-related requests. The company's October 19 updated safety roadmap states that existing policies primarily address dangerous-model deployment and that directly limiting the pace of research and development may be necessary in the future. It plans to put forward relevant policy proposals by January 15, 2027, or explain why it has not done so.
