Tencent rolls out AI model trained with limited cybersecurity data amid hacking fears

Nov 4 (Reuters) – Tencent on Wednesday released Hy4, its new open-source model, that the company ​said was trained ‌with limited cybersecurity data to “defensive” content to reduce the risks of the model’s ability to aid cyberattacks.

The ‌rollout ​comes after a ⁠slew of AI-driven ⁠cyberattacks around the world raised concerns about the capabilities of advanced models and the ​threat posed to global internet infrastructure.

Tencent said it filtered ⁠out content ⁠during training such as ​exploit development, reverse engineering, and penetration ​testing to limit Hy4’s potential “offensive” ‌capabilities.

Moonshot AI last month limited its newest model’s cyber-offensive capabilities, as Chinese AI firms ⁠join US companies to prevent loss-of-control risks.

“We recognize the potential safety risks ⁠posed ‌by advanced cyber ⁠and biological capabilities, and ​we ‌are committed to a ​more responsible ⁠approach to model training, open-sourcing, and release,” Tencent said in a statement.
