Anthropic Expands Mythos 5 Access to More Defenders, Unveils $35M Open Source Fund

Anthropic is expanding access to its advanced AI cybersecurity model, Mythos 5, to bolster defenses against cyberattacks. They are doing this through partnerships, a new open-source funding program, and an updated Claude Security offering, all designed to prevent direct access to the model while providing defenders with valuable security outputs like patch suggestions and vulnerability assessments. The company is also investing in open-source security and collaborating with government partners to protect critical infrastructure.
