Anthropic to bring back Fable 5 as US lifts export controls

Latest NewsPublishedJul 1, 2026

US Government Lifts Export Controls, Anthropic to Restore Access to Claude Fable 5

The US government has lifted export controls on Anthropic’s AI models, allowing the company to restore public access to Claude Fable 5 and Mythos 5. This decision comes after weeks of restrictions, which were imposed due to concerns about the potential misuse of these powerful models for malicious purposes. The restrictions had raised concerns about state control over AI technology and set a precedent for government intervention in the development of AI models.

Anthropic will redeploy Claude Fable 5 with a new set of classifiers designed to identify and block a broader range of cybersecurity-related tasks. The company has been working closely with the US government to analyze and approve Fable 5, ensuring alignment across the government and strengthening America’s leadership in AI. This collaboration is part of Anthropic’s efforts to scale up its work with the government on AI model testing and safeguards.

Concerns about Cybersecurity Threats

The export controls were initially imposed after a report revealed that researchers had bypassed Fable 5’s safeguards, prompting the model to identify software vulnerabilities. Anthropic has argued that this risk is not unique to Fable 5 and that weaker models could also identify the same vulnerabilities. The company is now drafting a consensus framework with partners, including Amazon, Microsoft, and Google, to assess the severity of AI jailbreaks and develop strategies to mitigate these risks.

Getting best tech deployed remains priority 

As the development of AI models continues to advance, it is essential to consider the potential risks and benefits of these technologies. The collaboration between Anthropic and the US government demonstrates the importance of working together to ensure that AI models are developed and deployed in a safe and responsible manner. If you’re interested in learning more about how AI is being used to earn passive income, consider joining the EcoPool Network, which offers a platform for earning rewards through Cloud Rewards and Green Crypto, using $ECP, the native coin of the EcoPool ecosystem.

With its user-friendly interface and robust security features, the EcoPool app provides a convenient and secure way to participate in the EcoPool Network and start earning $ECP today.

The restrictions came after the government became aware of a report in which Amazon researchers found a method of bypassing Fable 5’s safeguards, prompting the model to identify several software vulnerabilities. 

In a blog post, Anthropic argued this wasn’t a risk unique to Fable 5, as weaker models could also identify the same vulnerabilities and produce the same exploit.

AI jailbreak classifications proposed 

Anthropic has also begun drafting a consensus framework with Amazon, Microsoft, Google and other partners in its Project Glasswing — a collaboration announced in April to safeguard against AI cybersecurity threats — for “assessing the severity of AI jailbreaks.”

The company is also scaling up collaboration with the US government on AI model testing and safeguards. “This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research,” it stated.

A well-known AI researcher claimed to have jailbroken Fable 5 within 48 hours of its launch in June, before the government restrictions, and shared screenshots showing how he bypassed the model’s safety guardrails.
