Anthropic CEO Dario Amodei on Saturday called on frontier labs to slow the rate at which they improve AI capabilities so safety work can keep up, arguing that democracies must keep their lead over autocratic rivals — and, in cybersecurity, over widely available open-weight models — as large as possible. The plan lands as OpenAI has already described a shrinking “defender’s window” between trusted-access frontier cyber models and the open-weight systems attackers can already use.

Pace the frontier, defend the gap

Dario Amodei asks labs to slow capability gains so safety can catch up — and to keep closed, trusted-access models ahead of open-weight systems and autocratic rivals.

4–7 mo

Open-weight cyber lag vs closed frontier

6–12 mo

Amodei’s swarm / botnet risk window

3–5 yr

Window to widen a U.S. lead if controls hold

The preparation window is shrinking

Upper end of AISI’s measured open-weight cyber lag, in months. Each block is one month.

2025 lag
6–10 months

2026 lag
4–7 months

Takeaway: Defenders have less time before frontier cyber skill is broadly downloadable.

Three-step pacing plan

Step 1

Embedded evaluators

Employee-like access inside labs. Anthropic is committing now; OpenAI says it will match.

→

Step 2

Democratic coordination

Shared safety standards and limits on unchecked progress, likely needing an antitrust waiver.

→

Step 3

Global coordination

Deals with authoritarian governments only if defection can be verified or contained.

Support

Altman and Musk backed the evaluator pledge. Some security engineers say keeping frontier cyber models private cuts the public abuse surface.

Pushback

Critics say secrecy without shared evals starves independent red teams, and that the plan concentrates power in a few closed labs.
