Anthropic Suspends Top AI Models After U.S. Export Control Order — Nextgov/FCW

On June 12, the Commerce Department’s Bureau of Industry and Security ordered Anthropic to block all foreign nationals from accessing Fable 5 and Mythos 5. Because Anthropic couldn’t reliably screen users by nationality, it disabled both models entirely. The trigger: Amazon CEO Andy Jassy reportedly told Treasury officials that Amazon researchers had used Fable 5 prompts to extract information usable in cyberattacks — escalating a national-security case that also involved a technique to bypass the model’s safeguards.

Anthropic Disables Fable and Mythos AI Models Following U.S. Government Export Ban — Fortune

The June 12 BIS directive marks the first time the US government has ordered a leading AI lab to pull a live product offline on national-security grounds. The ban affects Fable 5 and Mythos 5 only — Anthropic’s other models remain accessible — but because the company cannot filter by nationality, it suspended both models for all customers worldwide while it works toward compliance. The episode sets a precedent that has rattled the broader AI industry and accelerated calls for a more nuanced export-control regime.

Nobel Laureate John Jumper Is Leaving DeepMind for Rival Anthropic — TechCrunch

John Jumper, who shared the 2024 Nobel Prize in Chemistry with Demis Hassabis for co-creating AlphaFold, is departing Google DeepMind after nearly nine years to join Anthropic. The move lands just days after Noam Shazeer — a VP of engineering co-leading Gemini — announced he was leaving Google for OpenAI. Anthropic has been building AI-for-science infrastructure throughout 2026, including wet labs and partnerships with the Allen Institute and Howard Hughes Medical Institute, suggesting it was laying the groundwork for a hire of Jumper’s caliber well in advance.

The Atlantic Created a Searchable Database of the Music Used to Train AI — The Verge

Journalist Alex Reisner has published four searchable datasets — totaling more than 20 million tracks — that reveal which songs were scraped to train AI music models including Suno and Udio. Two datasets contain 12 million and 9 million tracks respectively; the other two add roughly 200,000 more. Artists including Backxwash and Titus Andronicus have already confirmed finding their work in the databases. The disclosures hand plaintiffs in active copyright suits against Suno and Udio the concrete evidence they’ve lacked until now.
