The Trump administration has lifted export restrictions on Anthropic’s Mythos and Fable AI models, allowing the company to restore access to two of its most powerful systems after a short but controversial government-imposed freeze.
The U.S. lifted a requirement for Anthropic to obtain a license before exporting its Mythos and Fable models abroad, a rule that had effectively cut off public access to the advanced AI systems.
Anthropic to Restore Access on July 1
The rollback gives Anthropic a path to resume broader access quickly.
TechCrunch reported that Anthropic said it would begin restoring access to the models on Wednesday, July 1.
The Washington Post also reported that Anthropic confirmed in a social media post that it had received word from the Commerce Department that the ban was being lifted on both Fable and Mythos.
The restrictions were imposed earlier in June. On June 12, the U.S. government added Mythos and Fable to its list of export-restricted technologies, meaning they could no longer be made available to foreign nationals without special approval.
Commerce Secretary Says Anthropic Agreed to Security Steps
The reversal came after discussions between Anthropic and the U.S. government. Commerce Secretary Howard Lutnick said Anthropic agreed to proactively detect and address security risks associated with the models, work with the U.S. government on protocols and standards, and inform officials of malicious activity.
Anthropic also made changes to Fable. Anthropic said in a blog post that it had modified Fable 5 so that it was stricter in refusing cybersecurity-related requests.
Mythos and Fable Raised Cybersecurity Concerns
The models had drawn attention because of their advanced cybersecurity capabilities. Mythos was originally made available to select organizations in April to address concerns about its ability to identify and exploit software vulnerabilities, while Fable was released publicly in June with additional security guardrails.
The government’s approach has also affected OpenAI. OpenAI is still required to get government approval for new users of GPT-5.6. OpenAI’s latest models were also released to organizations approved by the Trump team instead of being immediately made public.
AI Policy Swings From Openness to Control
The episode shows how quickly U.S. AI policy is shifting. The Trump administration’s control over Anthropic and OpenAI customers marked a departure from Trump’s earlier push to loosen AI regulation and help the industry innovate quickly against China. The administration’s approach to AI policymaking has left companies with little clarity about what will govern future model releases.
For Anthropic, the rollback restores momentum after a disruptive access freeze. For the wider AI industry, it signals that frontier model releases may increasingly depend not only on technical readiness, but also on national security negotiations with Washington.
