The US government, citing national security authorities, issued an export control directive ordering the suspension of all access to Fable 5 and Mythos 5 — two Anthropic models — for any foreign national, regardless of whether they are inside or outside the United States. The directive explicitly covers foreign national Anthropic employees as well. Because Anthropic currently has no mechanism to verify the citizenship of its customers, the company chose to disable both models for its entire customer base to ensure compliance. Anthropic stated that other models are not affected and apologized for the disruption.

He notes personal financial consequences, having paid for access for employees who are not US-based and who are now locked out. The video also includes a sponsored segment for CodeRabbit's new agent product, which Theo describes as integrating with tools such as Sentry, PostHog, Jira, Linear, Notion, Google Drive, Datadog, and Google Cloud Logs, and billing based on agent time spent rather than per-tool usage.
