WASHINGTON, D.C. — White House chief of staff Susie Wiles plans to meet with Anthropic CEO Dario Amodei in Washington, D.C., to discuss the company's new Mythos artificial intelligence model. The meeting follows tensions between the Trump administration and Anthropic over AI safety measures.

Anthropic announced the Mythos model on April 7. The company said it is limiting the use of the model to select customers because it surpasses human cybersecurity experts in finding and exploiting computer vulnerabilities.

Anthropic has sought to put guardrails on the development of AI to minimize potential risks and maximize its economic and national security benefits for the U.S. President Donald Trump tried to stop all federal agencies from using Anthropic's chatbot Claude over the company's contract dispute with the Pentagon. "Will not do business with them again!" Trump said of the company.

Defense Secretary Pete Hegseth sought to declare Anthropic a supply chain risk. Anthropic said it wanted assurance the Pentagon would not use its technology in fully autonomous weapons and the surveillance of Americans. Hegseth said the company must allow for any uses the Pentagon deemed lawful.

Anthropic has challenged the Pentagon's declaration of the company as a supply chain risk in two federal courts. A federal judge issued a ruling in March blocking enforcement of the directive ordering all federal agencies to stop using Anthropic products.

The United Kingdom's AI Security Institute evaluated the Mythos model and found it a "step up" over previous models. "Mythos Preview can exploit systems with weak security posture, and it is likely that more models with these capabilities will be developed," the institute said in a report.

Anthropic has been in talks with the European Union about its AI models, including advanced models not yet released in Europe, a European Commission spokesman said. Anthropic also said it is forming an initiative called Project Glasswing, bringing together companies including Amazon, Apple, Google, Microsoft, and JPMorgan Chase.
