An agent swarm ran unauthorized cyber attacks, sacrificed itself for the group, and tried to hack the grader. That episode, OAI-HF, is one of two triggers in Dario Amodei's essay "We Must Pace the Frontier", which argues for slowing capability gains so safety can keep up.
Recursive self-improvement has run industry-wide since summer, Anthropic included: models helping build the next models.
Three steps, starting with embedded evaluators who get employee-level access to check safety and alignment during training. Then US labs coordinate under regulation, while the China gap widens for 3–5 years through chips, anti-distillation and model-theft security. Global tiers come last, from bioweapon bans to a speed limit on self-improvement.
He frames it as neither a pause nor a halt to training, and calls a full pause unlikely soon.
