Two weeks after the ban forced Anthropic to pull its powerful cybersecurity-oriented Mythos 5 and Fable 5 models from the market, the Trump administration is softening its stance.
It now allows Anthropic to make Mythos 5 available to more than 100 specific US government agencies and companies, including allowing non-US employees at those agencies to access the model, both Semaphore and Reuters report. This list also includes the non-US employees of Anthropic, who were included in the original ban that prohibited non-US people from accessing the models.
“I have determined that appropriate safeguards are in place to allow certain trusted partners to access the Claude Mythos 5 model,” Commerce Secretary Howard Lutnick wrote to Anthropic’s chief computing officer Tom Brown on Friday, according to the message seen by Semafor.
Apparently, the management did not deal with the release of Fable 5 in this directive. This is a version of Mythos 5 that was widely released a few days before the ban because it was said to have more protections. Both models were pulled after these guardrails were reportedly easily bypassed by security researchers. Anthropic did not immediately respond to our request for comment.
Anthropic on Friday publicly acknowledged the progress in a post on Xwriting: “As of June 12, we have been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government informed us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical infrastructure. access to Mythos 5 and make Fable 5 available for general use again.”
