The export controls were put in place after the Trump administration became alarmed by a threat intelligence report from Amazon claiming to have jailbroken Fable\u2019s cybersecurity capabilities.<\/p>\n
On X, Secretary of Commerce Howard Lutnick appeared to confirm that the restrictions would be lifted.<\/p>\n
\u201cOver the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the US Government and strengthen America\u2019s leadership in AI,\u201d Lutnick wrote.<\/p>\n
The administration levied the export controls after becoming concerned that the release of Fable 5 would lead to the model being jailbroken, giving users access to cybersecurity and other capabilities that Anthropic has said could wreak havoc on the open internet if\u00a0 placed in the wrong hands. The Amazon report convinced administration officials that such jailbreaks were on the immediate horizon.<\/p>\n
However, one oddity of the administration\u2019s decision is that the capabilities described in the Amazon report, by all accounts<\/a>, are not cutting-edge. Scanning code and breaking down how to exploit vulnerabilities for a user is already possible with existing models.<\/p>\n Anthropic confirmed that, saying that further testing found that equivalent and lesser models like ChatGPT 5.5, Claude Opus 4.8 and Kimi K2.7 could identify the same vulnerabilities as Fable did in the Amazon report, while a half dozen existing models were able to produce the same proof of concept code as Fable.<\/p>\n Crucially, Anthropic reiterated that they have yet to see a jailbreak that affects the model\u2019s restrictions on cybersecurity and biology work<\/a>, though they did call this instance \u201ca borderline case.\u201d Indeed, some cybersecurity professionals have publicly complained that existing safety guardrails on Fable 5 blocked many routine defensive cybersecurity work in addition to malicious use cases.<\/p>\n \u201cImportantly, the reported technique did not expose any unique Mythos-level cyber capabilities,\u201d the blog continued. \u201cThe behavior reflected a borderline case for Fable 5\u2019s safeguards\u2026there are some tasks that are unlikely to be dangerous but are nonetheless blocked by the safeguards out of an abundance of caution. The reported technique allowed access to one such behavior, but it only involved routine defensive cybersecurity work.\u201d<\/p>\n Anthropic said it has trained new safety classifiers to target and block the behaviors described in the Amazon report and notify users when it happens, and that the new safeguards have been stress tested by the federal Center for AI Standards and Innovation. The new classifiers will block the techniques \u201c99.9%\u201d of the time, but Anthropic said they\u2019re not expected to block all lower risk routine cyberdefense capabilities, just the most harmful ones.<\/p>\n The restrictions will likely make it even harder to use Fable 5 for defensive cybersecurity. One effect the company expects is that more \u201cbenign\u201d requests for routine coding and debugging tasks will be flagged by the system.<\/p>\n Christopher Padilla, former Assistant Secretary for Commerce for export administration in the George W. Bush administration, said that while it\u2019s \u201cgood news\u201d the controls have ultimately been lifted, the Trump administration\u2019s AI policy stumbles over the past two years illustrate \u201cthe risks of ad hoc, transactional policymaking.\u201d<\/p>\n In a LinkedIn post<\/a>, Padilla called the Trump administration\u2019s approach chaotic and unpredictable \u2014 the opposite of the clear, consistent rules industry depends on. While Vice President J.D. Vance mocked AI safety regulations<\/a> in a speech in Europe last year, the administration has quietly partnered<\/a> with OpenAI and Anthropic on voluntary national security testing, especially as frontier models began showing advanced automation and cyberattack capabilities.<\/p>\n That national security arrangement was supposedly codified<\/a> in a White House executive order last month, shaped heavily by industry boosters who feared regulatory delays would slow U.S. development. But days after Fable\u2019s release<\/a>, Commerce imposed new export controls on Anthropic\u2019s models anyway.<\/p>\n Padilla called proposed AI safety regulations by the Biden administration \u201cflawed and overly complex\u201d but nevertheless predictable compared to the status quo. Instead of replacing those proposed regulations with their own vision, the Trump White House has been \u201cto put it mildly, all over the place on AI policy.\u201d<\/p>\n
