Glasswing is designed to identify and fix vulnerabilities in critical
software using Claude Mythos Preview, which Anthropic describes as a "general-purpose, unreleased frontier model." Put simply, it marks the official use of AI by companies in the fight against AI itself with AI-enabled cyberattacks increasing by the day, the coalition of companies are fighting fire with fire.

Anthropic boasted that Mythos has already found thousands of high-severity vulnerabilities, identifying potential flaws in every major operating system and web browser including decades-old bugs missed by humans. Besides
detecting bugs, Mythos can also generate exploits and propose or generate patches for a complete cycle.

However, Mythos is only being used cautiously by the approved group of companies because Anthropic deems it too powerful and risky for an open release. If misused, it could drastically increase cyberattacks being that it's capable of generating exploits autonomously.

Delivered via cloud providers like AWS and Google Cloud, a further 40+ organizations who maintain critical software will also be able to gain access to the model. Are you a pro?

Mythos consistently outperforms Claude's own Opus 4.6 across agentic coding, reasoning and agentic search/computer use benchmarks, more than doubling the performance of Opus 4.6 on SWE-bench Multimodal.

Even with the proactive approach, Anthropic says companies alone aren't responsible for handling AI's effects on cybersecurity "frontier AI developers, other software companies, security researchers, open-source maintainers, and governments across the world all have essential roles to play."
