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)
According to The Information, sources say Anthropic may release its new model Claude Fable today. Described as a secure version of Mythos, Claude Fable retains some advanced capabilities while adding safety restrictions for high-risk scenarios such as cyberattacks. Anthropic previewed Mythos in April this year, stating that it can discover numerous previously unknown cybersecurity vulnerabilities—but did not directly release it due to potential safety risks. As of now, Anthropic has not officially announced detailed information about Claude Fable.
Odaily Seer monitoring shows that on Polymarket, the probability of "Claude Mythos model release date being June 10" is currently at 74%, up 24% in 24 hours. Additionally, the probability for "Release before June 12" stands at 83%; "Release before June 15" at 89%; "Release before June 22" at 95%; "Release before June 30" at 94%; and "Release before July 31" at 99%.Previously reported, tech journalist Alex Heath revealed that Anthropic will release a "public version of Mythos" tomorrow. The company plans to rename and slightly adjust Mythos, releasing it under the name "Fable 5."Odaily Seer continuously monitors the prediction market, seeing changes before pricing occurs.
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)
Odaily AI security startup Depthfirst has announced that its self-developed AI model outperforms Anthropic’s latest model, Mythos, in code vulnerability detection. It has discovered more critical security vulnerabilities at approximately one-tenth the cost, drawing attention from the cybersecurity industry.According to the company, a month before the launch of Mythos, it had previously claimed to have found a large number of severe vulnerabilities in key internet infrastructure code. Depthfirst now says its model has further identified multiple high-risk vulnerabilities that Mythos missed, all at a lower cost (approximately $1,000 compared to $10,000).Depthfirst CEO Qasim Mithani stated that the company has improved vulnerability detection efficiency through a “single-task-optimized AI model,” significantly reducing the cost of security analysis while enhancing coverage depth.The company completed $80 million in funding in March this year, achieving a valuation of $580 million. Alongside this, it launched the “Open Defense Initiative,” providing $5 million worth of AI detection credits to open-source developers and critical infrastructure projects for vulnerability scanning and security audits.

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.

According to Decrypt, Mozilla recently revealed that Anthropic’s latest AI model, Claude Mythos, identified 271 security vulnerabilities during internal testing of the Firefox browser; all related vulnerabilities were patched this week. For comparison, a previous Anthropic model had detected only 22 security-sensitive vulnerabilities. Mozilla stated that all discovered vulnerabilities fell within the scope of what top human researchers could identify. Claude Mythos was officially launched in March 2026 and is Anthropic’s most powerful model to date for reasoning, coding, and cybersecurity. It is currently available exclusively to vetted partners—including Amazon, Apple, and Microsoft—under Anthropic’s “Project Glasswing” initiative.
Odaily News Anthropic has decided to restrict the public release of its Mythos model due to its highly automated cyber attack capabilities. Reports indicate that during internal testing, the model was already capable of independently completing vulnerability discovery and exploitation processes, and generating multi-step attack plans.Informed sources stated that in early testing, Mythos could autonomously build intrusion tools targeting Linux systems and, with guidance, execute complex vulnerability chain attacks. These capabilities were assessed as potentially posing risks to global infrastructure.Anthropic's management ultimately positioned Mythos as a cyber defense tool and opened it for testing to select institutions in a restricted manner. Industry insiders pointed out that similar models could significantly enhance the efficiency of cyber offense and defense, while also potentially introducing new security challenges. (Bloomberg)
