Anthropic CEO Dario Amodei met with White House Chief of Staff Susie Wiles and Treasury Secretary Scott Bessent on Friday in what the White House called 'productive and constructive' talks over access to Mythos, Anthropic's frontier AI model capable of finding thousands of zero-day vulnerabilities. The meeting signals a thaw in the standoff that began when the Pentagon blacklisted Anthropic for refusing to drop safety restrictions on Mythos.

Why it matters

The conflict began when the Defense Department demanded unfettered access to Mythos, including for autonomous weapons and domestic surveillance, which Anthropic refused on safety grounds. The Pentagon then blacklisted Anthropic as a national security risk, effectively barring it from government contracts. This meeting represents an effort to find a compromise that would provide civilian agencies access to Mythos while excluding the Pentagon.

The details

Anthropic announced Mythos, its powerful AI cybersecurity tool, just 10 days after losing its appeal against the Pentagon's blacklisting. Mythos proved capable of identifying and exploiting thousands of previously unknown vulnerabilities across major operating systems and web browsers. Anthropic chose to restrict access to Mythos through a controlled program called Project Glasswing, providing the model to roughly 40 vetted organizations to find and fix vulnerabilities before they can be exploited. This decision to restrict rather than release Mythos is a direct application of the safety principles that put Anthropic in conflict with the Pentagon in the first place.

  • In late February, Defense Secretary Pete Hegseth demanded that Anthropic grant the Pentagon unfettered access to its AI models.
  • Anthropic sued the Trump administration in early March, filing two federal lawsuits alleging illegal retaliation.
  • On April 8, an appeals court reversed an initial decision to block the Pentagon's blacklisting of Anthropic.
  • Anthropic announced the Mythos AI model on April 7, 10 days after losing its appeal.
  • The meeting between Amodei, Wiles, and Bessent took place on Friday, April 18, 2026.

What they’re saying

“The meeting was introductory, productive, and constructive. We discussed opportunities for collaboration, as well as shared approaches and protocols to address the challenges associated with scaling this technology.”

— White House

“Mythos reveals a lot more vulnerabilities for cyberattacks.”

— Jamie Dimon, CEO, JPMorgan Chase

“Mythos is an inflection point for AI and global security.”

— Council on Foreign Relations

What’s next

The talks between Amodei, Wiles, and Bessent were described as introductory, signaling that a deal has not yet been reached. The litigation between Anthropic and the Trump administration is still active, and the Pentagon's blacklisting of Anthropic remains in place. However, the fact that the White House Chief of Staff and Treasury Secretary met with the Anthropic CEO represents a shift in the administration's posture, suggesting both sides are seeking a compromise that would provide civilian agencies access to Mythos while excluding the Pentagon.

The takeaway

This case highlights the complex balance between national security, commercial interests, and ethical principles in the development of powerful AI technologies. Anthropic's decision to restrict access to Mythos on safety grounds has put it at odds with the Pentagon, but the White House's outreach suggests a recognition of the technology's value and a desire to find a solution that satisfies all stakeholders.
