Anthropic on Tuesday said it’s expanding Project Glasswing to an additional 150 partners in more than 15 countries as companies test Mythos for software vulnerabilities.

The startup said the expansion includes industries that weren’t well-represented in the initial launch, such as power, water, healthcare, communications, and hardware. New partners will need to meet security requirements before gaining access to the model.

“This expansion is the next step toward our long-term goals: for AI to make all software more secure, and for us to help the industry adjust to how AI could change many of the core assumptions of cybersecurity,” the company said in a blog post.

Anthropic rolled out initial testing of Mythos to 50 partners in April after raising concerns about the model’s advanced cybersecurity capabilities. Worries that hackers could use Mythos to expose software vulnerabilities led to numerous conversations between the White House, Big Tech and financial institutions.

Since launch, Anthropic said Project Glasswing partners have unveiled more than 10,000 high or critical security flaws.

Anthropic’s Mythos expansion comes a day after the company said it confidentially filed its IPO prospectus with the SEC, beating rival OpenAI to the milestone. The AI lab on Monday also said it would start offering Mythos access to the European Union.
