Anthropic has retracted its Mythos and Fable 5 AI models following directives from the U.S. government to halt access to these models for foreign nationals.
- Anthropic has asserted that the purported security risk is negligible and is similarly present in widely accessible AI models.
- Ongoing legal disputes are between Anthropic and the U.S. government, stemming from the company’s refusal to permit blanket usage of its technology in military operations.
- Last month, Anthropic submitted its IPO documentation confidentially.
The company’s decision to withdraw its advanced AI models in response to U.S. security apprehensions has reignited concerns regarding the potential hazards posed by cutting-edge AI systems.
It has spurred discussions about the necessity for national AI technologies and has thrust the IPO-bound firm into a state of crisis, as per various reports on the social media platform X.
Recently, on Friday, Anthropic announced it would “suddenly disable” its most sophisticated AI models for all users, following a U.S. government order that mandated the suspension of access to these models for foreign nationals, citing national security issues.
The government contends that there exists a method to circumvent, or “jailbreak,” Fable 5, posing a potential hacking risk and triggering an export control directive.
In a blog post, Anthropic maintained that it had evaluated the vulnerabilities raised and found them relatively straightforward, noting that other publicly available models could exploit them without necessitating a bypass.
While complying with the order, Anthropic expressed disagreement, asserting that the identification of a minor potential jailbreak should not justify recalling a commercial model used by hundreds of millions.
What’s Behind the Focus on Anthropic’s AI?
Anthropic’s Mythos has recently garnered extensive scrutiny, as the company itself acknowledged its significant potency and the potential for harm, including cyberattacks, if manipulated by malevolent entities.
This week, the company introduced an AI model dubbed Claude Fable 5, representing a new echelon of capability categorized as “Mythos-class,” exclusively to a select array of enterprise clients. This model has been equipped with guardrails intended to prohibit its application in high-risk domains like cybersecurity.
This progression complicates an already tenuous relationship between the company and the U.S. government. Earlier in March, the U.S. government classified Anthropic as a “supply chain risk” after the company rejected requests to allow its AI technology for domestic surveillance and fully autonomous weapon systems.
In light of this designation, Anthropic has initiated legal action against the Pentagon, which has seen a judge assert that the Pentagon’s directive is unenforceable.
The Wall Street Journal reported on Sunday that Anthropic has dispatched key technical personnel to Washington in a bid to engage with government officials regarding these matters, following extensive discussions on Saturday.
These deliberations included notable figures such as Commerce Secretary Howard Lutnick and National Cyber Director Sean Cairncross, as well as Tom Brown, Anthropic’s co-founder and chief compute officer, alongside Sarah Heck, the company’s head of public policy, according to the Journal’s sources.
The Mythos and Fable Ban Stirs Sovereign AI Debate
In a comprehensive post on X, David Sacks, former AI and crypto advisor to President Donald Trump, expressed bewilderment at Anthropic’s reaction.
“A highly credible, trusted partner of both Anthropic and the U.S. government, who was testing Fable, disclosed a jailbreak of those guardrails. The Administration requested Dario to rectify the jailbreak or withdraw the model. Dario refused,” Sacks articulated.
Sacks further stated, “It is frankly perplexing that Anthropic has shown reluctance to adhere to safety requests that were previously touted as its utmost priority,” insisting that the government action is independent of the ongoing legal dispute. “The onus lies on Anthropic.”
Meanwhile, U.K. Prime Minister Mark Carney remarked that the U.S. export ban on Anthropic’s models underscores the vulnerabilities associated with reliance on a select few powerful AI tools, rekindling calls for sovereign AI systems in various nations.
“In this scenario, no wrongdoing has occurred, but we will indeed err if we merely accept this outcome, fail to extract lessons, and do not work to diversify,” Carney asserted to reporters on Sunday, as reported by Bloomberg.
Similarly, the European Union, which gained access to Mythos earlier in June after protracted discussions, asserted that the latest developments further emphasize “Europe’s imperative for technological sovereignty.”
Anthropic’s IPO May Encounter Challenges, Yet Retail Sentiment Remains Positive
This latest development could hinder Anthropic’s trajectory toward an initial public offering. Last month, the company confidentially filed for a U.S. IPO, positioning itself ahead of rival OpenAI in the race to enter public markets.

On Stocktwits, retail sentiments regarding ANTHZZX were overwhelmingly ‘bullish,’ with traders positing that the recent developments showcase the technological superiority and significance of Anthropic’s innovations.
“Anthropic surpasses all other AI offerings to such a degree that the United States cannot afford to let it reside in foreign control,” commented a trader.
