Anthropic is expanding its cybersecurity initiative, providing a new group of companies with access to its Claude Mythos Preview to find software vulnerabilities.
The artificial-intelligence lab launched the initiative, dubbed Project Glasswing, in April. At that time, roughly 50 partners including Apple, CrowdStrike, JPMorgan Chase, Microsoft and Palo Alto Networks were given access to the model.
Anthropic said Tuesday that those initial partners have so far found more than 10,000 high- or critical-severity security flaws from having deployed the model to scan their codebases for vulnerabilities.
The company said the new expansion of its Project Glasswing initiative marks the next step toward its goal of using AI to make all software more secure.
"Following several weeks of close collaboration with our Project Glasswing partners, the security industry, open-source software maintainers, and the US government, we're extending the partnership to approximately 150 new organizations," the company said, noting each must meet security requirements before gaining access.
The organizations included in the new group are based in more than 15 countries, with most providing critical infrastructure to many more, Anthropic said. It didn't detail the companies included in the expansion but said the group covers several industries that weren't well represented in the initial cohort, such as power, water, healthcare, communications and hardware.
"And many of the new partners are vendors--companies or nonprofits that maintain codebases that are relied upon by lots of other organizations around the world, including governments," it added.
The Project Glasswing expansion comes one day after Anthropic, which was recently valued at nearly $1 trillion, said it filed confidentially for an initial public offering, putting the company on a path to go public this fall.
