'Bitcoin Is Burning': Red Team Turns to Chinese AI to Find Flaws

In brief

• The Bitcoin Red Team is using Chinese AI models to search Bitcoin projects for security flaws.
• Calle said developers have confirmed numerous critical and high-severity vulnerabilities.
• They warned that unmaintained projects should not be trusted.

The Bitcoin Red Team is using Chinese AI models to search nearly the entire Bitcoin open-source ecosystem for security flaws, according to pseudonymous developer and Red Team lead Calle.

The volunteer group combines AI tools with human review to examine wallets, Lightning applications, software libraries, and other Bitcoin projects. Researchers privately report credible findings to developers so the flaws can be fixed before details are released.

“We’re experiencing a massive collision between decades of human open source slop against 2 weeks of Kimi K3,” Calle wrote Thursday on X. “Everything is broken, Bitcoin is burning.”

Kimi K3 is an AI model from Chinese startup Moonshot AI that developers can download and run on their own systems. It can analyze large codebases and complete lengthy software tasks with little supervision.

The Bitcoin Red Team has also used Chinese developer Z.ai’s GLM 5.2, as well as models from OpenAI and Anthropic. American models, though, come with limitations, and developers frequently run up against restrictions imposed by OpenAI and Anthropic when doing security research. “Red team rugged by OpenAI cyber again,” Calle posted earlier this week. “Don’t like asking for permission. Loading up Kiimi K3.”
