Anthropic abruptly disabled its newly launched Fable 5 and Mythos 5 AI models after receiving a US Commerce Department directive citing national security concerns. The Trump administration imposed export controls following reports of a jailbreak vulnerability, though Anthropic disputes the severity and argues the standard could halt all frontier AI development.
Anthropic Pulls Flagship AI Models After Government Order
Anthropic completely shut off access to its Fable 5 and Mythos 5 AI models on Friday night, just three days after their public launch, following a US government directive citing national security concerns
1
. The AI company received a US Commerce Department directive at 5:21 pm ET on Friday evening, subjecting the new models to government export controls that restrict their use by any foreign national, whether inside or outside the United States4
. To ensure immediate compliance, Anthropic was forced to disable both models for all customers worldwide, not just foreign nationals3
. Access to other Anthropic models remains unaffected by the directive1
.

Jailbreak Vulnerability Triggers Trump Administration Action
The directive stems from the Trump administration's concerns about a reported jailbreak vulnerability that circumvents safeguards designed to block Fable 5 prompts regarding cybersecurity, chemistry, and biology
1
. According to an Axios report, an administration official stated the government requested a pause to allow time for the "national security apparatus" to be "hardened" against this type of threat, a process that could take several weeks1
. However, Anthropic maintains the government has only provided "verbal evidence of a potential narrow, non-universal jailbreak" that involves asking the model to review a specific codebase for software flaws1
. The company says it has only seen evidence of this jailbreak being used to find "minor" and "relatively simple" software vulnerabilities, and that other publicly available models like GPT-5.5 have similar capabilities1
.Company Disputes Government's Safety Assessment
Anthropic publicly disagreed with the government's decision, arguing that "the finding of a narrow potential jailbreak should not be cause for recalling a commercial model deployed to hundreds of millions of people"
1
. The company warned that if this standard was applied across the industry, "it would essentially halt all new model deployments for all frontier AI development providers"1
. In its blog post, Anthropic emphasized that its strongest safeguards operate through independent classifier systems that function separately from the model itself, meaning that even if someone bypasses a refusal, the underlying protections against the most dangerous outputs remain in place3
. The company also noted that a review of recent usage found no evidence of those safeguards being successfully bypassed to produce harmful content3
.Research Community Caught in AI Governance Crossfire
The incident highlights growing tensions in AI governance and the precarious position of the research community, which finds itself increasingly dependent on AI models it does not control
2
. "A reckoning here is yet to come," says Rehaan Ahmad, co-founder of the open science research platform alphaXiv, describing this episode as "just the tip of the iceberg" in the struggle between regulating AI and giving free rein to research2
. Researchers had eagerly awaited Fable 5's release on June 9, as Anthropic had heavily promoted its scientific capabilities, particularly in biology2
. However, biologists like Sierra Bedwell, a Ph.D. student at the University of Illinois Urbana-Champaign, found themselves effectively locked out, with Fable 5 refusing to answer even basic questions about biology2
. The model's internal specifications also revealed that for any frontier AI research queries, it would silently degrade its capabilities in ways invisible to the user2
.Mythos 5 Background and Safety-First Approach Backfires
In April, Anthropic made waves by announcing it had created Mythos 5, an AI model it deemed too dangerous to release publicly, claiming it was powerful enough to identify vulnerabilities in every major operating system and web browser in use today
2
. The company only provided access to a select group of approximately 50 vetted organizations, including Amazon, Apple, Google, Microsoft, and CrowdStrike, through a controlled program called Project Glasswing for defensive cybersecurity work3
. Fable 5 was positioned as a safer version fitted with guardrails that block responses in high-risk areas, making it safe enough for general release while still being the most capable AI model available to the public according to benchmark tests from Vals AI3
