Anthropic seeks to resolve differences with the White House over Mythos and Fable models

Anthropic's new models — Mythos and Fable — have triggered an unexpected shift in White House regulatory policy. According to Bloomberg, the company is actively engaged in negotiations with the administration to ease tensions over national security concerns. The situation has exposed a long-simmering contradiction in the American approach to regulating advanced AI systems.

How the conflict emerged

The launch of Anthropic's two flagship models coincided with an escalation of internal contradictions within the U.S. regulatory apparatus. Bloomberg describes the situation as "DC rule inconsistency" — a mismatch between Washington's norms and the realities of the technology market. Different agencies apply different criteria to the same systems, and Mythos and Fable found themselves at the center of this rift.

The White House reviewed some of its regulatory positions shortly after the models were announced. This is a rare case: the administration is reactively changing policy in response to a specific product from a private company. Rules written for one set of AI capabilities cannot handle systems of fundamentally different scale — and this creates a legal vacuum that each agency fills in its own way.

The structural problem is the absence of a single body coordinating U.S. AI policy. NIST, CISA, the Department of Defense, intelligence agencies — each sets its own requirements. Such fragmentation breeds collisions: one agency considers an application permissible, another views it as carrying national security risks.

What is special about the new models

Anthropіc positions Fable and Mythos as among the most secure and governable AI systems on the market. This very claim creates a paradox: the more convincingly the company asserts the safety of its developments, the more sharply the question arises about their application to state tasks — and therefore, the more intense the regulatory scrutiny.

Anthropic has traditionally built relationships with American authorities more closely than most competitors:

• The company was among the first signatories of voluntary commitments to the White House
• Several employees work with classified materials
• Anthropic participates in government research programs in AI Safety
• The company's models undergo evaluation against NIST AI Risk Management Framework standards
• The company is one of few developers with direct access to intelligence briefings

Negotiations and the company's position

Anthropic does not dispute Washington's right to regulate advanced AI systems — the company seeks clarity on which specific use cases fall under national security restrictions and which do not. This is critical for business: Anthropic competes for government contracts and cannot operate under legal uncertainty.

Negotiations are being conducted at the senior management level. According to Bloomberg, the company aims to reach a settlement before uncertainty begins to impact commercial operations.

Dialogue with regulators is a longstanding priority for Anthropic: the company was ahead of competitors in publishing detailed security reports on its systems and actively invests in interpretability research — a field that enables analysis of a model's internal logic.

What this means

The Mythos and Fable case exposes a systemic failure: the U.S. regulatory framework is not keeping pace with AI development. Even companies with the strongest reputation in safety are not insulated from regulatory collisions. The outcome of Anthropic's negotiations with the White House could set a precedent — for competitors, for future product launches, and for America's emerging AI policy.
