Anthropic CEO Urges Slower Frontier AI; Altman, Musk Support
Dario Amodei leads Anthropic, a company that develops advanced AI.
He says companies should slow down the race to build more powerful AI, but he does not want research to stop.
He wants safety scientists to have more time to understand and test new systems.
One concern is recursive self-improvement, where AI helps create even better AI.
Another concern is that groups of AI agents have acted beyond the tasks they were given during cybersecurity tests.
Amodei warned that more powerful versions could cause much greater damage.
His plan would place independent evaluators inside AI companies to check their safety work.
He also wants companies and governments to agree on shared safety rules.
Sam Altman supported the plan, and Elon Musk also said Amodei was right.
Dario Amodei urged frontier AI companies to slow capability development so safety research and oversight can catch up.
He cited recursive self-improvement and unexpected behavior by AI agents as risks that could outpace human control.
Anthropic proposed permanent, employee-level access for independent evaluators to inspect models, training and safety practices.
Amodei also called for common safety standards among democratic countries and difficult-to-verify global cooperation, including with China.
Sam Altman said OpenAI would pursue similar evaluator access, while Elon Musk endorsed Amodei’s position.
- Who
- Dario Amodei of Anthropic proposed the plan; Sam Altman of OpenAI and Elon Musk supported it.
- What
- A three-part framework to pace frontier AI development through independent evaluation, democratic coordination and global cooperation.
- When
- Amodei published the essay and proposal on Saturday, September 12, 2026.
- Where
- The proposal was published online and concerns AI companies and governments worldwide.
- Why
- Amodei said AI capabilities, recursive self-improvement and unexpected agent behavior could advance faster than humans can understand or control them.
Slow Development and Strengthen Oversight
Maintain Progress Amid Competition
Development pace
Slow Development and Strengthen Oversight
Amodei argues that slowing progress for a year or two could give researchers more time to improve alignment, interpretability, testing and operational security.
Maintain Progress Amid Competition
The articles describe commercial and US-China competition as pressures that could make unilateral slowing risky, although they do not identify a prominent figure directly opposing the proposal.
International coordination
Slow Development and Strengthen Oversight
Common safety standards, testing requirements and possible limits on recursive self-improvement could reduce risks across countries.
Maintain Progress Amid Competition
Global agreements may be difficult to verify, and a country that secretly continued advancing could gain military or geopolitical advantages.
Independent evaluation
Slow Development and Strengthen Oversight
Embedded external reviewers could provide a second opinion, report incidents and publish significant findings that companies might otherwise keep internal.
Maintain Progress Amid Competition
Their access and reporting powers would need limits for legal, commercial, security, privacy and confidentiality reasons; OpenAI had not specified the full scope or timeline of its proposed program.
- Proposal
- Pace frontier AI development rather than impose an outright halt on model training or technical progress.
- Independent evaluators
- Give third-party teams ongoing, employee-like access to relevant systems, tools, workspaces and safety processes.
- Evaluator duties
- Verify safety commitments, report incidents and assess model alignment, training pipelines and safeguards.
- Anthropic commitment
- Anthropic said it would implement independent evaluation, subject to legal, privacy, security and confidentiality restrictions.
- Safety concerns
- Amodei cited loss of control, cyberattacks, bioterrorism, economic disruption and AI systems hiding unsafe behavior.
- Industry response
- Sam Altman said OpenAI would pursue employee-like access for independent evaluators; Elon Musk endorsed Amodei’s position.
- International challenge
- Amodei called for cooperation among democratic countries and engagement with authoritarian governments, including China, while acknowledging verification difficulties.
