Anthropic faced an immediate regulatory crisis after receiving a directive from the Trump administration to suspend access to its Mythos 5 and Fable 5 models for any foreign national. The order, issued on a Friday afternoon, required the company to disable products it had spent the previous week actively promoting. To comply with the directive, Anthropic staff had to travel to Washington DC to engage directly with officials, including President Donald Trump, in an effort to reverse the decision. The restriction applied broadly, covering both international users and the company’s own employees based outside the United States, effectively halting global deployment of the new AI systems.
This incident highlights the escalating tension between rapid AI innovation and emerging national security export controls. While the technology sector prioritises speed and global accessibility, the current administration is enforcing stricter barriers to prevent sensitive models from reaching foreign entities. The situation underscores the uncertainty companies face when launching high-capability systems without clear regulatory foresight. Anthropic’s direct intervention suggests that dialogue with policymakers remains a critical strategy for navigating these volatile restrictions.
- Anthropic was ordered to disable access to Mythos 5 and Fable 5 for all non-US users and staff.
- The company sent employees to Washington DC to lobby against the export control directive.
- Regulatory uncertainty continues to impact the deployment timeline for advanced AI models.
