The June 12 export control directive came after Amazon researchers found a method of prompting Fable 5 to identify software vulnerabilities and, in one case, produce code showing how one could be exploited. <\/p>\n
They reported it to the Commerce Department rather than to Anthropic directly, a decision worth noting, given that Amazon is also Anthropic’s largest outside investor.<\/p>\n
The order required Anthropic to restrict access to all foreign nationals, including its own non-citizen staff. Because Anthropic had no way to verify user nationality in real time, it shut both Fable 5 and Mythos 5 down for everyone worldwide.<\/p>\n
More AI:<\/strong><\/p>\n Anthropic’s counter-argument was specific. Its own testing found the same vulnerabilities could be flagged by far weaker models, including its own Claude Opus 4.8, OpenAI’s GPT-5.5, and China’s Kimi K2.7. <\/p>\n Every model the company tested could produce the same exploit code demonstration as Fable 5. According to Anthropic’s announcement, the flagged behavior amounted to routine defensive cybersecurity work, not a unique capability of Fable 5.<\/p>\n Notably, CEO Dario Amodei took a hands-off role in the Washington negotiations. Co-founder Tom Brown and Head of Public Policy Sarah Heck led the discussions at the Commerce Department and Office of the National Cyber Director, a deliberate choice to reduce friction with an administration with which Amodei had publicly clashed earlier in the year.<\/p>\n Commerce Secretary Howard Lutnick announced the resolution on July 1 via X (the former Twitter).<\/p>\n “Over the past two weeks, we have worked closely with Anthropic to analyze and approve Fable 5 to ensure alignment across the U.S. Government and strengthen America’s leadership in AI,” Lutnick wrote.<\/p>\n The core technical fix is a new safety classifier trained to block the specific jailbreak technique Amazon reported in more than 99% of cases. The government’s Center for AI Standards and Innovation (CAISI) independently tested and approved the new safeguards before the export controls came off.<\/p>\n When the classifier blocks a request, the user gets redirected to Claude Opus 4.8 and notified. The tradeoff is more false positives on routine coding and debugging requests, a cost Anthropic accepted in exchange for clearing the government’s concerns. The company confirmed the resolution in a June 30 press release.<\/p>\n “As of today, June 30, the export controls on Fable 5 and Mythos 5 have been lifted.”<\/p>\n Fable 5 returned July 1 on Claude Platform, Claude.ai, Claude Code, and Claude Cowork for users globally, CNBC reported. Pro, Max, Team, and select Enterprise subscribers get up to 50% of weekly usage limits included through July 7 as compensation for the disruption, after which the model requires usage credits. AWS, Google Cloud, and Microsoft Foundry access is being restored separately.<\/p>\n As part of the deal, Anthropic committed to pre-release government access for future frontier models, rapid information sharing on jailbreak findings, and a new HackerOne program through which security researchers can submit Fable 5 vulnerabilities for review.<\/p>\n M.Santiago/Getty Images<\/p>\n<\/figcaption><\/figure>\n The timing of the disruption could not have been more sensitive. Anthropic had confidentially filed an S-1 with the SEC on June 1 for a potential IPO, after raising a $65 billion Series H at a $965 billion valuation, as Fortune reported.<\/p>\n When the shutdown happened in June, Anthropic’s pre-IPO perpetual contract on the onchain exchange Hyperliquid fell about 3.7%, according to CoinDesk. Investors were reassessing the risk of a public listing for a company whose flagship models could be pulled without warning.<\/p>\n Enterprise clients felt the disruption more practically. Businesses in finance, health care, and critical infrastructure lost access to AI systems embedded in production workflows with no prior notice. <\/p>\n American Banker reported that some industry observers were already asking whether companies should rethink their reliance on frontier model vendors that can be shut down overnight by government directive.<\/p>\n The regulatory picture beyond this episode also carries some weight. Defense Secretary Pete Hegseth designated Anthropic a supply-chain risk in March, The Hill confirmed, a separate dispute the company is still contesting.<\/p>\n The Amazon conflict of interest adds another layer. Anthropic’s largest investor reported a jailbreak to the government before informing Anthropic. That dynamic introduces ongoing tension in the company’s most important commercial and government relationships simultaneously.<\/p>\n Nineteen days from shutdown to global restoration is a number that matters for the IPO story. <\/p>\n Public market investors and enterprise clients were both watching what Anthropic did with a genuine crisis. Papers and policy commitments are one thing. An actual government-ordered shutdown is the real test. <\/p>\n Anthropic handled this one in under three weeks, with CAISI sign-off and a new industry framework attached.<\/p>\n The four-criteria jailbreak scoring system Anthropic is developing with Amazon, Microsoft, and Google could end up as the most consequential outcome of the whole episode. <\/p>\n The AI industry still lacks an agreed-upon way to communicate how dangerous a jailbreak actually is, which is partly why a borderline safety finding turned into a 19-day global shutdown.<\/p>\n The most severe findings trigger immediate mitigations. <\/p>\n A 24\/7 monitoring team watches jailbreak submission channels. If the framework gets adopted broadly, future findings would go through a structured triage process rather than escalating directly to emergency export controls.<\/p>\n Anthropic framed the framework as an invitation, not just an announcement, calling on other AI developers to join. <\/p>\n The June 2 White House Executive Order on AI innovation and security, which Anthropic helped shape over 10 weeks of agency discussions, creates a policy environment where a shared jailbreak standard could become government-recognized practice.<\/p>\n That would give Anthropic lasting influence over how AI safety gets measured and enforced across the industry, well beyond the resolution of one 19-day ban.<\/p>\n Related: Amazon CEO just made things uncomfortable for Anthropic<\/strong><\/p>\n #Anthropic #landed #biggest #win<\/p>\n","protected":false},"excerpt":{"rendered":" On June 12, Amazon engineers handed a report to the U.S. Commerce Department.
