Can Chinese AI companies curb cyber risks from open-weight models without losing their edge?

Tencent Holdings said it stripped its latest Hy4 model of cyber-hacking capabilities while retaining cyber defence capabilities, following a similar move by Moonshot AI with its Kimi K3.1 Pro, as Chinese AI model companies begin curbing the cybersecurity capabilities of their most advanced open-weight models after a string of high-profile AI hacking incidents involving US and Chinese companies. The moves raise the question of whether Chinese AI companies can reduce cyber risks from open-weight models without losing their competitive edge.
