Anthropic has expanded Project Glasswing, the initiative that aims to highlight and fix software vulnerabilities using the powerful Claude Mythos AI model.
The generative AI vendor has approved 150 new organizations as partners to receive the model, the company said in a statement.
Mythos first came to public notice in March, when Anthropic restricted its rollout to 50 key partners — including AWS, Apple, Google, Microsoft, Nvidia and Broadcom — amid fears about the potential consequences should the cybersecurity model fall into the wrong hands.
Last week, Anthropic provided an update on how it was performing, highlighting a prolific success rate, including identifying thousands of security flaws across codebases it deemed fundamental to the functioning of the internet and its infrastructure over a matter of months.
The vendor reiterated that Mythos was not yet ready for widespread release but hinted at an expansion that has now been confirmed. According to Anthropic, each new partner will “need to meet our security requirements before they gain access.”
The group covers several industries underrepresented in the initial rollout, including organizations in the power, water, healthcare, communications and hardware sectors, according to Anthropic. Many of the new partners are companies or nonprofits that maintain codebases that many organizations around the world rely on, including governments, the vendor said.
A commonality among the new partners was that a major codebase attack would be catastrophic, Anthropic stated. The vendor did not name any of the new organizations.
In the future, Anthropic, currently moving forward with plans for an IPO, will expand Glasswing’s geographical reach even further.
The urgency with which Claude Mythos is being implemented is driven by a desire to set safeguards and operating norms for the wave of low-cost, fast and powerful AI models that Anthropic said are anticipated.
Rival OpenAI released a similar model, GPT-5.5, with a stronger focus on security and is being used by partners, while other developers are set to follow suit.
