Anthropic's Amodei calls for industry-wide AI speed limits

Anthropic CEO Dario Amodei published an essay proposing a three-step "pace the frontier" plan: unilaterally give third-party evaluators like METR deep access to Anthropic's models, extend that access industry-wide, and eventually pursue global agreements modeled on the SALT nuclear disarmament treaties. He warned that recursive self-improvement could threaten the internet's stability within six to twelve months.

Why it matters: This is a notable shift from "race to the frontier" rhetoric toward a coordinated slowdown, coming from the CEO of a leading lab rather than an outside critic, and it lands just as Anthropic reportedly prepares history's largest IPO, creating tension between commercial pressure and its own safety message. It also echoes Sam Altman's parallel comments about pausing training, suggesting the two top labs may be trying to jointly shift industry norms.
