Anthropic's new AI Mythos Preview model will help Apple find vulnerabilities in iOS, macOS, and Safari.

Anthropic has announced Project Glasswing, a new initiative that will allow technology companies to use its new AI model Mythos Preview to identify and fix security vulnerabilities or weaknesses in operating systems and web browsers. According to Anthropic, Mythos Preview has already identified thousands of zero-day vulnerabilities.
“AI models have reached a level of coding where they can outperform all but the most skilled humans in finding and vulnerabilities software,” Anthropic said. “Given the pace of AI progress, it won’t be long before such capabilities become widespread, possibly beyond the actors committed to developing them safely. Project Glasswing is an urgent effort to put these capabilities to use for defensive purposes,” the company added.

Anthropic Project Glasswing: Use by selected partners
The Mythos Preview will not be available to the public. Instead, Anthropic said that use of the model will be limited to select partners, with the initial group, in addition to Anthropic itself, including Apple, Amazon Web Services, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA and Palo Alto Networks.

Anthropic is committed to providing up to $100 million in usage credits for Mythos Preview.
Beyond that, partners will have to pay to use the AI model. Initial partners, such as Apple, will use Mythos Preview as part of their defensive security work, according to Anthropic.

This means Apple can use the AI model to help find and fix security vulnerabilities across its Safari browser and operating systems, which include iOS, iPadOS, macOS, watchOS, tvOS, and visionOS .
Rumors also suggest that Apple is developing a homeOS for a new smart home hub.

Anthropic’s Project Glasswing initiative clearly highlights the new reality in cybersecurity: AI is no longer just a tool for innovation, but also a critical factor in defending against increasingly complex threats. With Mythos Preview demonstrating capabilities that surpass human performance in detecting vulnerabilities, companies like Apple gain a powerful advantage in protecting their ecosystems and their users.

At the same time, limiting access to select partners underscores the seriousness and potential risk of this technology. The balance between leveraging AI for defensive purposes and preventing its malicious use will be a determining factor for the future of cybersecurity. In this context, initiatives like Glasswing may not just be an innovation, but a necessary evolution in securing the digital world.
