Anthropic on Tuesday said an additional 150 partners in more than 15 countries will gain access to its powerful Mythos artificial intelligence model, which has proven adept at finding software vulnerabilities.

The startup said the expansion of Project Glasswing 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 makeallsoftware 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's Mythos expansion comes a day after the AI lab said it would start offering access to the European Union. On Monday, the company also confidentially filed its initial public offering prospectus with the Securities and Exchange Commission, beating rival OpenAI to the milestone and paving the way for a significant AI share sale.

In April, Anthropic rolled out initial Mythos testing to 50 partners amid concerns over the model's advanced cybersecurity capabilities.

Many experts warned that these capabilities existed beforehand, but hackers could use Mythos to expose software vulnerabilities more quickly.

As worries mounted, the White House held numerous meetings with Big Tech leaders and financial institutions to discuss ways to safely deploy advanced AI models in the era of Mythos.

Since launch, Anthropic said Project Glasswing partners revealed more than 10,000 high or critical-level security flaws. The company estimates that a major cyberattack could impact more than 100 million people.

Major Project Glasswing partners include Apple , Nvidia , Microsoft , CrowdStrike and Palo Alto Networks . Anthropic did not disclose the new companies joining the coalition.

Cloud data management platform Rubrik said it was among the new batch of companies in a release.
