Odaily Odaily报道，The U.S. government ordered Anthropic to suspend access to its latest AI model for foreign nationals due to national security concerns, following which Anthropic disabled access to Fable 5 and Mythos 5 for all users. Grayscale Head of Research Zach Pandl noted that this move exposes the risks of centralized control over frontier AI technologies and will drive market demand for decentralized alternatives.Within 12 hours of Anthropic cutting off access, the Bittensor token TAO rose 30%, reaching $283 on Monday, a nearly three-week high. Pandl expects that as investors seek alternatives to centralized AI, demand for decentralized AI platforms like Bittensor will continue to rise. (cointelegraph)

the U.S. government's export controls and access restrictions on Anthropic's models, Fable 5 / Mythos 5, were partly driven by Amazon's cybersecurity research and AWS CEO Andy Jassy's communications with the White House.It is understood that research submitted by Amazon indicated that through a series of prompt tests, researchers could induce Fable 5 to output sensitive information potentially usable for cyberattacks, raising security concerns. Subsequently, Andy Jassy reported these findings to the U.S. government level, prompting the White House to implement further restrictions, including banning foreign users from accessing the model.Meanwhile, former U.S. Commerce Department official Kate Koren revealed that the White House's existing policy stance towards Anthropic may have also influenced this decision. This is because Anthropic has disagreements with the White House over the boundaries of AI safety, including refusing to use its models for mass surveillance or lethal autonomous weapons systems. Although the two sides had eased tensions and expanded cooperation earlier this year, this incident could reignite strained relations between them. (The Wall Street Journal)
David Sacks, co-chair of the President's Council of Advisors on Science and Technology, responded to the regulatory implications of the Anthropic “security controversy,” stating that he has communicated with multiple parties regarding the current situation at Anthropic. He concluded that the core of the event lies in the security controversy sparked by its newly released model “Fable” (the commercial version of the Mythos-class models). Although Anthropic publicly stated the vulnerability was “not severe,” the U.S. government and testers disagreed with this assessment, believing it was significant enough to impact the model's security, even involving “cyber weapons operability” risks.David Sacks further criticized that Anthropic has long emphasized “safety first,” yet in this instance, it was more inclined to keep the consumer version continuously online rather than prioritizing the repair of the security issue. He stated this matter should not be conflated with previous defense or regulatory controversies and noted that the U.S. government still recognizes Anthropic's technical capabilities. The current problem “could have been resolved quickly, the ball is in Anthropic's court.”
a16z co-founder Marc Andreessen published a highly satirical long-form post on platform X, centered around the topic of "AI regulation." Through two extreme narratives, he presented the conflicting positions on this issue.In the narrative "against AI regulation," Marc Andreessen portrays regulation as a force that stifles innovation, potentially killing garage startups, weakening the Silicon Valley ecosystem, increasing compliance burdens, and limiting the development of AI and computing infrastructure. He sarcastically notes, "If US AI regulators had policed our grandfathers, they would have banned the use of horse-drawn carriages."In the narrative "supporting AI regulation," Marc Andreessen uses irony to describe the order, safety, and expansion of the industrialized compliance system that regulation could bring. This includes a massive compliance industry, strengthened government regulatory frameworks, and social redistribution mechanisms.However, Andreessen does not offer a single conclusion in the article. Instead, through highly exaggerated language, he highlights the long-term structural conflict and rift within AI regulation between "innovation freedom" and "safety governance."In previous news, Anthropic issued a statement saying that the US government issued an export control directive under the guise of national security authority, requiring the suspension of all foreign entities' access to AI models Fable 5 and Mythos 5, regardless of whether the personnel are within the United States, including Anthropic employees who are foreign nationals.
the U.S. government has issued an export control directive citing national security authority, requiring the suspension of all access for foreign nationals to Fable 5 and Mythos 5, including Anthropic’s foreign national employees. To ensure compliance, Anthropic must close all customer access to Fable 5 and Mythos 5, while all other Anthropic models remain unaffected.The U.S. government provided oral evidence indicating a potential narrow-scope, non-general jailbreak method for the model. Anthropic is complying with the government's legal directive and removing all user access to Fable 5 and Mythos 5, but disagrees with the decision to withdraw deployed commercial models based on the discovery of a narrow-scope potential jailbreak, and is working diligently to restore access as soon as possible.
Anthropic CEO Dario Amodei has stated that if new AI models pose specific risks, governments should have the authority to prevent their deployment. In a lengthy post on Wednesday, Amodei argued that AI models should undergo mandatory third-party testing to assess potential risks across multiple domains. He wrote that if an AI is deemed to pose "unacceptable risks," then "governments should have the power to block or constrain its deployment." This is one of Amodei's strongest statements to date advocating for stricter AI regulation. "I believe that, at least during this current exponential growth phase, the most appropriate analogy is cars, airplanes, or pharmaceuticals—technologies that are essential to the modern economy but can also lead to significant loss of life if poorly designed or misused," Amodei wrote. Anthropic has previously warned that its AI model, Mythos, possesses the ability to discover and exploit critical software vulnerabilities, leading the company to restrict access to a small number of partners. This week, Anthropic also released a new version that removes related cybersecurity attack capabilities. (Jinshi)
Odaily reports: Artificial intelligence company Anthropic has agreed to provide a special briefing to relevant officials of the Financial Stability Board (FSB) regarding its Mythos AI model. The briefing will focus on security vulnerabilities identified by the model within the defense systems of the global financial network.According to two sources familiar with the matter, the communication was proposed by Bank of England Governor Andrew Bailey, requesting that Anthropic brief the FSB on its new preview version of the Claude·Mythos AI model. The FSB is currently compiling a report on compliance standards for the application of artificial intelligence in the financial industry, with a draft expected to be released next month for public consultation. Both the FSB and Anthropic have declined to comment on their recent communications. (Jiemian)
in April 2026, two major DeFi attacks on Drift Protocol and Kelp DAO resulted in losses of nearly $600 million, triggering approximately $9 billion in capital outflows from protocols like Aave. TRM Labs investigator Nick Carlsen stated that a hacker group suspected to be linked to North Korea has allegedly used AI to assist in target selection and attack path design. Failsafe CEO Aneirin Flynn said that AI has compressed the time for discovering blockchain vulnerabilities from months to days or even hours. The report noted that Anthropic has not fully opened its AI model Mythos due to cybersecurity risks, claiming the model has the capability to discover large-scale zero-day vulnerabilities. Its research indicates that over half of blockchain attacks in 2025 could theoretically be completed autonomously by AI. (Bloomberg)
the White House has recently opposed Anthropic's proposal to expand the use of its AI model, Mythos, to approximately 120 companies, primarily based on security and computing power concerns. Anthropic had originally planned to add 70 new companies to the roughly 50 enterprises currently using Mythos, but the White House has raised doubts, worrying that insufficient computing power might affect the government's own usage of Mythos.Launched in early April, Mythos is designed to detect and exploit critical software vulnerabilities. It is currently limited to testing by enterprises managing key infrastructure, with no plans for public release. The White House fears that expanding usage to more commercial users could create a computing power bottleneck for the government when using the model. This is particularly concerning given Anthropic's computing power procurement agreements with Amazon, Google, and Broadcom—though contracts have been signed, new capacity has not yet come online.On the political front, relations between the White House and Anthropic have not eased. The Trump administration has publicly criticized Anthropic for hiring multiple former officials from the Biden administration and expressed dissatisfaction with its ties to liberal organizations. One example highlights the trust issues between the two sides: Collin Burns, a former researcher at Anthropic who was originally assigned to a government AI model evaluation role, was replaced by senior White House officials upon learning of his background, to avoid having AI company personnel directly involved in matters concerning dealings with other AI companies.Additionally, last week Anthropic disclosed an unauthorized access incident involving the Mythos model, further intensifying external regulatory scrutiny on the company.
, Anthropic and OpenAI have experienced security incidents in succession, drawing market attention to the security of AI models themselves. Currently, Anthropic is investigating a possible case of unauthorized user access to its Claude Mythos model. Almost simultaneously, OpenAI was also reported to have accidentally opened access to several unreleased models within its Codex application.Analysts believe that such incidents highlight that even AI model providers focused on cybersecurity capabilities still face significant security challenges. While AI is increasingly used for cyber defense, platform security and access control are becoming critical risk points.Industry insiders point out that these vulnerability incidents have intensified scrutiny over the security governance capabilities of AI companies, and also reflect that the security systems of current AI technology still need improvement amid rapid development.
