Tencent Launches New AI Model With Restrictions Designed to Prevent Cyberattacks

China

Chinese technology giant Tencent has released Hy4, a new artificial-intelligence model developed with safeguards intended to prevent its misuse in cyberattacks and harmful biological research. The company says its cybersecurity training was restricted to defensive applications, including identifying software vulnerabilities and helping developers repair them. Training material relating to building hacking tools, breaking into computer systems and exploiting weaknesses was excluded.

Tencent reported that its internal security testing found no evidence that Hy4 significantly increased users' ability to conduct cyberattacks or bypass security protections. The launch comes amid growing international concern about increasingly sophisticated AI-powered cybercrime. Tencent also announced plans to release the model's weights and a technical report detailing its safety testing, reflecting the growing importance of AI security as China and the United States compete for technological leadership.
