Anthropic works to resolve White House friction over its Mythos and Fable models

Anthropic's new models, Mythos and Fable, have triggered an unexpected reversal in the White House's regulatory policy. According to Bloomberg, the company is actively negotiating with the administration to defuse tension over national security. The episode has exposed a long-brewing contradiction in the US approach to regulating advanced AI systems.

How the conflict arose

The release of Anthropic's two flagship models coincided with sharpening internal contradictions within the US regulatory apparatus. Bloomberg describes the situation as a "DC rule inconsistency": Washington's rules do not match the realities of the technology market. Different agencies apply different criteria to the same systems, and Mythos and Fable ended up at the center of that gap.

The White House revised some of its regulatory positions soon after the models were announced. It is a rare case: an administration reactively changing policy in response to a specific product from a private company. Rules written for one set of AI capabilities cannot cope with systems of a fundamentally different scale, which creates a legal vacuum that each agency fills in its own way.

The structural problem is the lack of a single body coordinating US AI policy. NIST, CISA, the Department of Defense and the intelligence agencies each set their own requirements. This fragmentation produces conflicts: one agency considers a use acceptable, while another sees it as a national security risk.

What is special about the new models

Anthropic positions Fable and Mythos as among the safest and most controllable AI systems on the market. That creates a paradox: the more convincingly the company asserts the safety of its products, the sharper the question of using them in government tasks becomes, and the closer regulators look.

Anthropic has traditionally built closer ties with US authorities than most of its competitors:

• The company was in the first wave of signatories to voluntary commitments to the White House
• Several employees work with classified materials
• Anthropic takes part in government AI Safety research programs
• The company's models are assessed against the NIST AI Risk Management Framework
• The company is one of the few developers with direct access to intelligence agency briefings

Negotiations and the company's position

Anthropic does not dispute Washington's right to regulate advanced AI systems. It is seeking clarity on which usage scenarios fall under national security restrictions and which do not. This is critical for the business: Anthropic competes for government contracts and cannot operate amid legal uncertainty.

The talks are being held at the top-management level. According to Bloomberg, the company aims to reach a settlement before the uncertainty begins to affect its commercial operations. Dialogue with regulators is a long-standing Anthropic priority: the company began publishing detailed safety reports on its systems before its competitors did, and it invests heavily in interpretability research, a field that makes it possible to analyze a model's internal logic.

What this means

The Mythos and Fable case exposes a systemic failure: the US regulatory framework is not keeping pace with AI development. Even companies with the best safety reputations are not immune to regulatory collisions. The outcome of Anthropic's talks with the White House may set a precedent for competitors, for future product launches and for Washington's emerging AI policy.
