TL;DR
Anthropic’s Mythos models have been offline for two weeks following US export restrictions. Negotiations with the government are ongoing, but no resolution is in sight, impacting the company’s prospects and the US AI industry.
Anthropic’s Mythos-class AI models have been offline for two weeks following a US government order to suspend access due to security concerns, with negotiations between the company and the Trump administration still unresolved.
On June 12, the US Department of Commerce issued an export control order demanding that Anthropic suspend access to Mythos 5 and Fable 5 for all foreign nationals, citing national security concerns. Since then, Anthropic has kept the models offline, citing ongoing negotiations and a lack of clarity on the regulatory framework for AI export controls.
Anthropic has declined multiple requests for comment, and sources indicate that negotiations involve high-level executives, including cofounder Tom Brown, but progress remains slow. The company’s leadership has expressed concern over the indefinite shutdown affecting its revenue plans, especially as Mythos models were key to its IPO strategy and financial stability. Meanwhile, the US government has not provided a clear explanation for why the models are still restricted, despite previous assessments suggesting they were safe to release.
Industry experts warn that the lack of a clear legal framework for applying export controls to advanced AI models has created a bureaucratic deadlock, with potential consequences for the US’s position in global AI development.
Impact on US AI Industry and Global Competitiveness
The prolonged shutdown of Mythos models highlights the broader risks of uncertain AI regulation, which could hinder US companies’ ability to innovate and compete internationally. With other nations, notably China, advancing rapidly in AI capabilities, the US risks falling behind if regulatory delays persist. The case also raises concerns about the stability of the US AI ecosystem, which relies heavily on exports and international cooperation.
Furthermore, the situation underscores the potential for government actions to stifle innovation and create a chilling effect on AI research, especially when legal and security frameworks are unclear. Industry leaders warn that this could lead to a power vacuum, prompting global competitors to fill the gap and accelerate their own AI development efforts.

US Export Controls and the Mythos Model Controversy
The US Department of Commerce’s June 12 order targeted Mythos 5 and Fable 5, citing security concerns related to their capabilities. Learn more about Anthropic’s Mythos controversy. While the agency initially tested Fable 5 without objections, a later flagged vulnerability led to the suspension. Experts like Katie Moussouris argue that the vulnerability was overblown, and that the model’s ability to review code and identify security flaws is essential for cybersecurity defense. The lack of a clear legal process for AI export controls has caused delays, with negotiations hampered by bureaucratic complexities and political considerations.
Prior to the restrictions, Anthropic had positioned Mythos as a key revenue driver, with plans for an IPO and partnerships with major firms like SpaceX, Google, and Amazon. The restrictions threaten these plans, while the US government’s stance has caused concern about the future of AI export controls and international competitiveness.
“The vulnerability cited shouldn’t have triggered such a severe government response. It’s a vital tool for AI security work, not a guardrail bypass.”
— Katie Moussouris, CEO of Luta Security
