# US Export-Control Directive Cuts Off Foreign Access to Anthropic's Fable 5 and Mythos 5

The United States has classified two frontier models as controlled technology, and talks to reverse the order have failed, leading Europe to reconsider its dependence on American artificial intelligence (AI).

The United States government has issued an export-control directive ordering Anthropic to suspend all access to its two most capable models, Fable 5 and Mythos 5, according to a [statement the company published](https://www.anthropic.com/news/fable-mythos-access) on June 12. The order treats access to the models themselves, not just their weights or training hardware, as a controlled item.

The restriction targets foreign users. The Russian-language technology outlet AI ML Big Data [reported](https://t.me/ai_machinelearning_big_data/10336) that the directive closed access to Fable 5 and Mythos 5 for people without US citizenship, and that the European Commission said it had begun assessing the consequences for European users and companies that had built on the models.

Talks between the Trump administration and Anthropic to lift the controls ended without an agreement, AI Post [reported](https://t.me/aipost/7260), citing WIRED. US officials reportedly remain concerned that Fable 5 can be jailbroken to unlock capabilities the government wants to keep restricted. That concern, if accurate, treats the model not as an ordinary commercial product but as a dual-use technology whose safety controls the government does not fully trust.

What is verified is narrow. Anthropic confirms that the directive exists and that it has suspended access. The jailbreak rationale comes from anonymous officials through a single news outlet and has not been independently reproduced. The scope, duration, and appeal process remain unstated in public documents.

## What this means

This is the clearest evidence yet that access to frontier models is becoming an instrument of state power rather than an open market. For engineers and companies outside the United States, the practical risk is no longer only that a model is deprecated, but that it is revoked by a government with no notice and no substitute of equal capability. That strengthens the case for sovereign and open-weight alternatives.

## What to watch

- Whether the European Commission moves from assessment to a formal response, such as procurement guidance that steers institutions toward European Union (EU) hosted or open-weight models.
- Whether other US labs receive similar directives, which would signal a category-wide policy rather than a model-specific one.
- Any public technical detail about the jailbreak concern, which would let independent researchers test the claim.
