| Mythos, interrupted: Axios reports that the administration is “blocking foreign governments, companies and individuals” from accessing Anthropic’s most advanced AI model—Mythos, also called Fable. The company decided to entirely block access to that model instead. Rumors have swirled claiming that Chinese hackers got access; other sources assert that Amazon found vulnerabilities with the model and flagged them for the administration.
“Commerce Secretary Howard Lutnick on Friday sent a letter to Anthropic CEO Dario Amodei saying [Mythos] would be subject to export controls to any location outside of the U.S. and to all foreign persons within the country,” continues Axios. This includes foreign nationals at Anthropic, who are now blocked from working on that product.
“Anthropic tightly controlled the release of Mythos, which was launched in April, limiting access to a select group of companies that could use it to plug security holes,” notes Semafor. “The plan was to ensure its capabilities wouldn’t make it into the hands of hackers. Anthropic has said Mythos represents a danger to the public because of its ability to find bugs in computer code, which could be exploited by malicious actors.”
“Fable is Mythos with guardrails,” writes David Sacks, a venture capitalist and adviser to President Donald Trump. “But if those guardrails fail, then you’ve exposed Mythos and its advanced cyber capabilities to people who shouldn’t have them. (Keep in mind that Anthropic itself widely promoted the idea that Mythos was a cyberweapon and needed to be regulated as such. They asked for government regulation of Mythos and championed the guardrails on Fable. If there is a vulnerability—big or small—it is Anthropic’s responsibility to patch.)”
Sacks continues: “A highly credible trusted partner of both Anthropic and the USG who was testing Fable came forward with a jailbreak of those guardrails. The Admin asked Dario to fix the jailbreak or de-deploy the model. Dario refused.”
Anthropic, meanwhile, doesn’t seem to believe the jailbreak was serious: “Given that perfect jailbreak resistance does not appear to be possible today, Anthropic adopted a defense in depth strategy with Fable 5,” writes the company in a press release. “We aimed to make jailbreaks either narrow (in the case of non-universal jailbreaks) or very expensive to produce (in the case of universal jailbreaks), and to combine this with thorough monitoring to quickly detect and shut down any successful attacks. This is also why Anthropic has required 30-day retention of customer data with Fable—a policy change that carries real costs for us with customers, but that allows us to research and mitigate jailbreaks….
“We are complying with the government’s legal directive and are removing access to Fable 5 and Mythos 5 for all users,” continues the company. “However, we disagree that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people. If this standard was applied across the industry, we believe it would essentially halt all new model deployments for all frontier model providers.”
According to Sacks, “The Admin’s hope now is that Anthropic remediates the safety issue, the export control is lifted, and Fable goes back into general release. The Admin wants all of this to happen as soon as possible. It is frankly bewildered [sic] that Anthropic hasn’t wanted to comply with safety requests that it previously said were its highest priority.”

Scenes from New York: On Saturday, the Knicks won their first NBA championship since 1973. Here’s a sweet clip from air traffic control in San Antonio, Texas (where they beat the Spurs) congratulating them on their victory as their pilot flies them back to New York. You can hear the celebrating.
And here’s Jalen Brunson, after Game Four, just being a really good guy. Not to mention Jose Alvarado’s celebratory dance moves. A really cool team with a ton of talent (and history playing together). |
