- David Sacks alleged that Anthropic CEO Dario Amodei refused to "fix the jailbreak or de-deploy the model" after a "highly credible trusted partner" reported a Fable jailbreak
- Anthropic publicly released its Mythos class models earlier this week under the commercial name Fable before the government intervened
- The US government ordered Anthropic to take Fable 5 and Mythos 5 offline, citing national security concerns, and the models remain suspended
- Anthropic blocked access to all customers worldwide to comply, calling the situation a "misunderstanding" in coverage by Moneycontrol
- Dario Amodei had himself previously warned that Mythos posed a national security threat, per Business Insider's framing of the shutdown
- Coverage by The Independent and Ars Technica links the order to a directive from the Trump administration, while Axios connects it to a broader national security dispute
Why it matters: This marks the first US government-mandated takedown of a frontier commercial AI model, establishing a precedent for Washington to compel labs to pull products over national security risks. The irony is sharp: Anthropic's CEO had publicly flagged the same national security concerns that triggered the shutdown, yet David Sacks frames the episode as the company failing to act on a credible jailbreak report—suggesting the government determined Anthropic's own self-regulation was insufficient.
