What does the new security guardrail do?

When users try to access restricted capabilities related to cybersecurity and biology, they are notified their request is blocked and it is processed by the less-advanced Opus 4.8 AI model instead. The safeguard extends to requests related to a specific behavior identified in an Amazon paper, addressing a workaround where users could bypass restrictions by asking the model to fix code rather than identify security issues.

Is Anthropic's regulatory situation fully resolved?

No. While the Commerce Department lifted export controls on Fable 5 and Mythos 5, Defense Secretary Pete Hegseth has told advisers there is no clear path to lift his February 28 order designating Anthropic a supply chain risk.

Trump Administration Lifts Export Controls on Anthropic's Claude Models

Send on LINE

3 Key Points

What happened
The Trump administration removed export restrictions on Anthropic's Claude Fable 5 and Mythos 5 AI models after the company agreed to extend a security guardrail. The new safeguard blocks users from accessing certain restricted capabilities related to cybersecurity and biology, routing those requests to the less-advanced Opus 4.8 model instead.
Why it matters
The export controls had effectively taken Fable 5 offline after the administration learned that users could bypass restrictions by asking the model to fix code rather than identify security issues. Commerce Secretary Howard Lutnick's decision to restore access signals that the administration believes Anthropic's new safeguards are robust enough to address those concerns, though the company still faces a separate designation as a supply chain risk from the Defense Department.
What to watch
While Anthropic has resolved the Commerce Department impasse, Defense Secretary Pete Hegseth has indicated there is no clear path to lift his February 28 order designating the company a supply chain risk, meaning the company's regulatory challenges with the administration are not entirely resolved.
