Claude Mythos: Anthropic Tests Its AI in Claude Code

Claude Mythos: Towards Integration in Claude Code?

Anthropic, the company specializing in artificial intelligence, may soon integrate its advanced cybersecurity model, Claude Mythos, into its development tool, Claude Code. This hypothesis is based on recent clues that have caught the attention of users during experimental testing.

Accumulating Clues

Since April, Claude Mythos has been presented as an AI with highly advanced cybersecurity capabilities. Recently, some users noticed the temporary appearance of an option "claude-mythos-1-preview" in Claude Code, suggesting a potential integration of Mythos into this tool designed for programmers. This discovery did not go unnoticed among regulars of the experimental builds.

The Capabilities of Mythos

Anthropic unveiled Mythos in April as part of the Glasswing project. At that time, the company highlighted the model's exceptional capabilities in cybersecurity. According to Anthropic, Mythos could detect critical vulnerabilities in complex software and systems, be significantly more autonomous than current versions of Claude, and outperform Opus 4.7 on certain code-related reasoning tasks.

However, Anthropic does not hide the potential risks. The firm claims that Mythos can also generate functional cyberattacks at a very professional level. In other words, this model not only fixes vulnerabilities but also fully understands how to exploit them. This is precisely why Mythos has never been made public until now.

Towards an Automated Security Audit Tool

If the integration of Mythos into Claude Code is confirmed, Anthropic could transform its programming assistant into an automated security audit tool. Indeed, the model could analyze code, detect complex vulnerabilities, propose fixes, or simulate attacks to test the security of an application. For companies, the promise is enormous: detecting flaws even before production represents a colossal gain in time, money, and likely in crises avoided.

A Cautious Approach

Unlike the race for "more powerful" solutions led by several players in the AI field, Anthropic is trying to maintain a very cautious discourse around Mythos. And for good reason, according to the company, the model has already enabled the detection of over 10,000 critical or high-severity vulnerabilities in just one month through its Glasswing program. Partners like AWS and Google are also participating in these experiments. The goal is clear: to use AI to identify flaws before malicious actors can exploit them.

The problem is that an AI capable of automating the discovery of zero-day vulnerabilities can also become a nightmare if it falls into the wrong hands. Anthropic thus seems to be seeking the impossible balance: to offer a tool powerful enough without turning the internet into a giant playground for opportunistic hackers. Because Mythos in Claude Code is certainly not just a simple new AI tool for developers. We will see if the company actually goes ahead with deploying this technology in Claude Code.
