360 Security Technology unveiled Yitian Tulong at ISC.AI 2026 in Beijing — two AI models for vulnerability discovery and automated defense.
Tulongfeng positioned as “Chinese Mythos” for identifying software flaws. Yitianzhen handles automated defense and incident response.
Tulongfeng reportedly found 3,432 software flaws including 105 confirmed by Chinese government.
While acknowledging 20-30% capability gap vs US models, Zhou Hongyi emphasized building a professional attack-and-defense team over relying on a single advanced model — contrasting with what he described as US focus on a “genius model” approach.
Strategy prioritizes comprehensive operational capability via agent engineering over raw frontier compute parity.
Announcement follows US export controls on Anthropic Mythos, blocking foreign access to the vulnerability-discovery system.
