Cloudflare Tests AI Bug Hunter Mythos Across 50+ Repos

Cloudflare has spent the last few months putting security-focused LLMs through their paces on its own infrastructure — and one model called Mythos is turning heads.

The company tested Mythos against more than 50 repositories. The standout finding: Mythos can chain multiple bugs together into a single working exploit. That's not just finding vulnerabilities — it's thinking like an attacker.

Cloudflare also detailed a vulnerability discovery harness built to systematically evaluate how these AI models perform at sniffing out security flaws. The harness provides a structured way to benchmark LLM capabilities in real-world security scenarios.

Worth noting: this is still in the testing phase. Cloudflare hasn't announced a product launch or deployment. But running AI security models against live infrastructure at this scale signals serious intent to bake LLM-driven vulnerability detection into its security stack.
