WASHINGTON, April 9, 2026 – Anthropic’s announcement of Project Glasswing on Tuesday made one thing clear: AI is now as capable as any highly trained experts at identifying software vulnerabilities.

Project Glassjaw, a partnership between Anthropic, Apple, Nvidia, Amazon Web Services, J.P. Morgan Chase, Google and others will provide Anthropic’s new frontier model “Claude Mythos” to fix vulnerabilities or weaknesses in their foundational systems.

Anthropic’s relationship with the federal government remains soured after Wednesday’s decision by the D.C. Court of Appeals which allowed the Pentagon to continue its blacklist of the company after a dispute between the company and Secretary of Defense Pete Hegseth on the deployment of Claude in fully autonomous weapons.
