Anthropic is bringing back Fable 5 after a dispute with the Trump administration led to the suspension of access to its most powerful publicly available AI model.
"We've received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5," Anthropic said in a statement posted to X on Tuesday. "We'll begin restoring access tomorrow, and will share an update soon. We're grateful to our users for their patience, and to everyone who worked with us on redeploying the models."
On June 12, Anthropic announced it had to "abruptly disable" access to Fable 5 and Mythos 5 after the Trump administration issued an export control order requiring the AI company to suspend any foreign nationals, including Anthropic's employees, from accessing either model. Mythos 5, the latest update to Anthropic's Claude Mythos Preview, had not been widely released to the public as the AI company said that the model's hacking capabilities were still too powerful.
In wake of the export control order, which Anthropic maintained was based on a misunderstanding of a possible Fable 5 "jailbreak," company officials traveled to Washington D.C. to try to resolve the issue with the White House.
The administration's order illustrated the degree to which one of the world's leading AI companies continues to struggle with its relationship with the government. In March, Defense Secretary Pete Hegseth formally labeled Anthropic as a supply chain risk. Anthropic later sued the Trump administration to overturn Hegseth's order. The suit remains ongoing.
Anthropic's latest dust-up with the White House comes as the company marches toward an IPO that could occur as soon as this year. On June 1, Anthropic announced that it had confidentially filed an S-1 draft, the first step toward going public.
Anthropic's Mythos AI model has previously made waves among governments and companies around the world.
In April, Anthropic announced that the first iteration, Claude Mythos Preview, would only be released to a select number of companies as part of what it deemed Project Glasswing because the AI model was too adept at finding and exploiting cybersecurity vulnerabilities. By holding off on a public release, Anthropic said it hoped to give companies time to bolster their cybersecurity defenses.
President Donald Trump's recent AI executive order, which allows leading AI companies to voluntarily allow the US government to review advanced models up to 30 days before their public release, came on the heels of the Mythos moment.
