U.S. Department of Commerce lifts export controls on Anthropic Fable 5 and Mythos 5 models
According to Reuters, the U.S. Department of Commerce has officially lifted export controls on Anthropic's two AI models, Claude Fable 5 and Mythos 5, less than three weeks after the control order was issued. Anthropic stated that access to the aforementioned models will be restored starting from the following day. Previously, on June 12, Anthropic was forced to urgently take the two models offline due to national security risks; on June 27, the U.S. government partially lifted the ban, allowing Mythos 5 to be open to certain "trusted" U.S. institutions. U.S. Secretary of Commerce Howard Lutnick stated that over the past two weeks, the government has worked closely with Anthropic to complete the review and approval of Fable 5, ensuring it aligns with the overall stance of the U.S. government and strengthens U.S. leadership in the AI field.

The U.S. partially eases export restrictions on Anthropic, marking a new phase of tiered AI regulation liberalization
the U.S. Department of Commerce has made differentiated adjustments to export restrictions on frontier models from AI company Anthropic, signaling that global AI regulation has entered a new phase of "tiered liberalization." The policy shows that the official ban on exporting Claude Mythos 5 has been lifted, allowing specific compliant and controlled users to resume using this cybersecurity model. Meanwhile, another high-end model, Fable 5, remains under export restrictions, with related policy consultations still ongoing.Industry analysts indicate that this layered control model—loosening restrictions in some areas while tightening in others—reflects the U.S. balancing act between national security, data sovereignty, and international AI competition. As the global AI race continues to accelerate, specialized models capable of vulnerability exploitation are facing increasingly stringent scrutiny from various countries. Multiple nations have initiated discussions on establishing a unified cross-border regulatory framework for frontier AI capabilities. (Forbes)

Anthropic's Restricted Spillover Effect Emerges: Asian AI Companies Simultaneously Launch Rival Frontier Models
as Anthropic faces export restrictions limiting the global availability of its advanced models, multiple Asian AI companies are accelerating efforts to fill the market gap. Chinese cybersecurity firm 360 Security Technology has reportedly launched an AI tool called "Tulongfeng," claiming it can directly compete with Anthropic's high-end model "Mythos." Meanwhile, its more restricted version, "Fable 5," also falls within the scope of relevant export controls.In the same week, Japanese AI startup Sakana AI released a new model named "Fugu," taken from the Japanese word for pufferfish. It is positioned as a frontier model designed for agents. The company stated that the model's capabilities are comparable to Fable 5 and Mythos Preview, and it supports coordinating multi-model calls via API to enable agent orchestration.Sakana AI emphasized that the timing of this release and the U.S. export restrictions are "purely coincidental," but the product's official website still clearly promotes "providing frontier capabilities without the risk of export controls." Company co-founder David Ha stated that future AI development will shift from competition among single large models to "model orchestration systems," adding that "access can disappear at any time, and distributed intelligence is a realistic hedge against the risks of centralization."On the other hand, Chinese 360 founder Zhou Hongyi views AI vulnerability detection capabilities as a "national strategic asset" and warns of the so-called "one-way transparency" risk, where certain entities may monopolize advanced security capabilities.According to reports, the U.S. export restrictions on Anthropic's advanced models have been in place for about two weeks. Against this backdrop, Asian manufacturers are accelerating the launch of local alternatives. Although some companies still emphasize the importance of American models in the Asian market, the trend of differentiation within the regional AI ecosystem has begun to emerge. (TechCrunch)

LinkedIn Co-Founder: xAI Is “a Disaster”; SpaceX “Buys Its Way” into the AI Race
Reid Hoffman, co-founder of LinkedIn and investor in Anthropic and OpenAI, recently shared his views on the “Pioneers of AI” podcast, offering assessments of several AI companies. Hoffman bluntly stated that SpaceX “is not an AI company,” describing its acquisition of Cursor and other moves as “buying relevance with money,” and labeled xAI as “a complete disaster”—all 11 of xAI’s original co-founders have departed, the company has undergone three reorganizations, and its flagship model Grok consistently lags behind competitors in benchmark tests. Regarding the U.S. government’s order—citing export controls—for Anthropic to delist its Fable and Mythos models, Hoffman expressed strong concern, criticizing the government’s approach as “authoritarian and principle-free,” and pointing out the stark asymmetry in regulatory standards applied to Anthropic versus OpenAI. Furthermore, Hoffman argued that Anthropic and OpenAI are not engaged in zero-sum competition; rather, each holds distinct advantages—in coding, design, legal frameworks, and consumer-facing applications—and both stand poised to become “infrastructure-level” companies in the AI era. He also announced his resignation from Microsoft’s board to fully dedicate himself to Manas AI, an AI-driven drug discovery company.

Viewpoint: Mythos’ breach of the NSA signals that AGI is drawing near; 9% inflation will not become the norm
Anthony Pompliano, Chairman of Bitcoin treasury company ProCap Financial, posted on X stating that Mythos allegedly breached the U.S. National Security Agency’s (NSA) classified systems within hours—a development that will further intensify public concerns about AI risks and prompt increased regulatory intervention. Yet the more critical signal conveyed by this incident is that AGI (Artificial General Intelligence) is, in fact, drawing near. Current AI technologies not only surpass humans in capability but are also self-training and improving at an incomprehensible pace—“humans cannot compete with these models.”

Polymarket probability of "Claude Fable 5 restored for US customers before July 1" rises to 73%, up 33% in 24H
Monitoring by Odaily Seer Prophet Channel shows that the probability of "Claude Fable 5 restored for US customers before July 1" on Polymarket has risen to 73%, up 33% in 24H.If Anthropic reopens Claude Fable 5 (or Claude Mythos, or a version confirmed to be the same model) to the US public before the specified date, this event will settle as "Yes"; otherwise, it will settle as "No". Qualifying methods of restoration include public beta or public waitlist; closed testing and private access do not count. Other models such as Haiku, Sonnet, and Opus are not included by default unless they are confirmed to be the same model as Claude Fable 5. Settlement will primarily be based on official announcements from Anthropic, supplemented by consensus reports from mainstream media.Due to export controls imposed by the US government on national security grounds, Anthropic urgently suspended global access to the Claude Fable 5 model just days after its release on June 9. Although the restrictions were primarily aimed at foreign users, due to the difficulty of real-time user identity screening, Anthropic ultimately closed access for all users, including those in the US, and switched requests to less capable models such as Opus 4.8. Anthropic is currently engaged in high-level discussions with the White House on issues including model capabilities and potential jailbreak risks. The company has publicly stated that the ban may have stemmed from a misunderstanding and is actively pushing to restore access.Odaily Seer Prophet Channel continues to monitor the prediction market, seeing changes before they are priced in.

Anthropic Model Safety Controversy Escalates, Amazon Accused of Being the "Hidden Force" Triggering Regulatory Intervention
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 responds to Anthropic “security controversy” triggering regulation: Core conflict is unpatched vulnerability
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.”

Zcash Founder Says Claude Mythos Audit Found No Critical Vulnerabilities
Odaily Zcash founder Zooko Wilcox posted on X stating that a security audit conducted by Anthropic's Claude Mythos AI model did not find any "more severe vulnerabilities" in the Zcash protocol. The audit was commissioned by Shielded Labs, a Swiss non-profit organization supporting Zcash development. On June 3, Zcash developers temporarily paused Orchard transactions after discovering a vulnerability in the shielded pool, restoring functionality through an emergency upgrade the same day. The issue stemmed from a four-year-old forging vulnerability in the Orchard shielded pool, identified by security researcher Taylor Hornby with the assistance of Anthropic's Claude Opus 4.8 model. The Zcash Foundation stated there is no evidence that the vulnerability was exploited, nor was any unauthorized value creation detected, and user privacy remained unaffected.Anthropic released the first public version of the Claude Mythos model, Fable 5, on Tuesday, and stated on Friday that it has suspended access to the Fable 5 and Mythos 5 AI models due to export control directives issued by the U.S. government citing national security concerns.
