Anthropic: The US government has requested the suspension of foreign national access to Fable5 and Mythos5 to ensure compliance and will disable the relevant models for all users

2026.06.13 09:01:09

**Breaking: Anthropic Disables Fable 5, Mythos 5 Under U.S. Export Control Directive** June 13 — Anthropic confirmed today the U.S. government issued a national security-linked export control directive, ordering immediate suspension of all foreign national access to its Fable 5 and Mythos 5 models—whether located inside or outside the U.S., including its own foreign national employees. To comply, Anthropic must block all user access to the two models. Other Anthropic AI models remain unaffected. The directive arrived at 17:21 ET with no specific details on the national security concerns driving the order. The government’s apparent concern centers on a narrow, non-generalizable technique to spot minor, pre-known vulnerabilities in a demo environment—a capability already available from other public AI models, no jailbreak needed. Anthropic notes tools like OpenAI’s GPT-5.5, used daily by cybersecurity defenders to secure systems, can perform the same task. Pre-launch, Fable 5 underwent thousands of hours of red team testing with the U.S. government, UK AISI, private third parties, and internal teams. The tests found Fable 5’s security measures far stronger than any prior deployed AI, and no widespread jailbreak method was uncovered. The government only provided a verbal hint of this narrow potential issue, not concrete proof. Anthropic will comply with the directive to pull Fable 5 and Mythos 5 access, but disputes the decision to take a commercial model used by millions offline over a narrow, unproven jailbreak risk. The firm warns such a standard would block all leading AI providers from launching new models, calling for a transparent, fact-based government process for AI security. Anthropic labels the action a misunderstanding and says it’s working to restore access as soon as possible.

Oman has proposed establishing a regional co-governance mechanism for the Strait of Hormuz, and Iran may abandon its sole control over the waterway.

According to Reuters, Gulf sources revealed that Oman has put forward a proposal to Iran aimed at establishing a mechanism for the joint management of the Strait of Hormuz by regional countries, adopting a voluntary toll model to fund initiatives including navigation management, environmental protection, and search and rescue operations. Sources noted that under the proposal, Iran would not hold sole control over the Strait of Hormuz. The plan draws on the management model of the Strait of Malacca, allowing relevant parties using the strait to voluntarily contribute funds for maintaining channel safety and related services. To date, Oman’s proposal has secured regional backing.

South Korea plans to cap individual stock leveraged investment at 20%, and will prioritize monitoring the effectiveness of the new policy taking effect on July 31.

According to South Korea’s JoongAng Ilbo, South Korea’s financial regulatory authorities today decided that if overheating in single-stock leverage product investments fails to abate, additional regulatory measures including individual investment caps will be implemented. The authorities are currently focusing on studying a plan to limit individual stock leverage investments to within 20% of total financial investment holdings. Today, Financial Services Commission Chairman Lee Eog-yun stated at a forum that they will first closely monitor the policy effects of supplementary measures such as enhanced margin requirements that took effect on July 31. Lee added that if demand does not sufficiently cool, additional measures will be researched and prepared in advance. It is understood that the plan under study involves setting aggregate management rules, capping the share of individual stock leverage in total financial investment holdings at 20%. For instance, if an investor’s total financial investment holdings amount to 100 million won, they can allocate a maximum of 20 million won to single-stock leverage products.

The user wants me to write a headline for a Lookonchain tweet about an abnormal order that caused liquidations. Let me extract the key information: - An abnormal order pushed $SKHX below $930 - This triggered over $80M in $SKHX liquidations - Trader 0xc985 was liquidated - His position: 2,026 $SKHX ($2.08M) long - Loss: $260K Requirements: - Max 120 characters - Concise English headline - Keep tickers ($SKHX), key amounts, names - No quotes, no hashtag symbols, no trailing period - ONLY output the headline Key elements to include: - $SKHX (the ticker) - The liquidation amount ($80M or reference to large liquidations) - Maybe the individual trader loss for human interest Let me draft options: 1. "Abnormal order triggers $80M+ $SKHX liquidations, trader 0xc985 loses $260K" - Let me count: A-b-n-o-r-m-a-l- -o-r-d-e-r- -t-r-i-g-g-e-r-s- -$-8-0-M-+- -$-S-K-H-X- -l-i-q-u-i-d-a-t-i-o-n-s-,- -t-r-a-d-e-r- -0-x-c-9-8-5- -l-o-s-e-s- -$-2-6-0-K = about 75 characters. Good. 2. "$80M in $SKHX liquidations after abnormal order, trader 0xc985 loses $260K" - about 78 characters 3. "Abnormal $SKHX order triggers $80M liquidations, 0xc985 suffers $260K loss" - about 75 characters Let me verify the first one stays under 120 and captures the essentials: "Abnormal order triggers $80M+ $SKHX liquidations, trader 0xc985 loses $260K" That's clean and includes the key ticker, the large liquidation amount, and the individual trader's loss. Abnormal order triggers $80M+ $SKHX liquidations, trader 0xc985 loses $260K

An abnormal order briefly pushed $SKHX below $930, triggering more than $80M in $SKHX liquidations. Trader 0xc985 was one of the victims. His 2,026 $SKHX ($2.08M) long position was fully liquidated, resulting in a $260K loss.
