China’s Kimi K3 fuels fears safety curbs are holding back US AI

# China’s Kimi K3 calls US safety curbs on top AI models into question Source: [https://www.scmp.com/tech/tech-trends/article/3361358/chinas-kimi-k3-fuels-fears-safety-curbs-are-holding-back-us-ai](https://www.scmp.com/tech/tech-trends/article/3361358/chinas-kimi-k3-fuels-fears-safety-curbs-are-holding-back-us-ai) Chinese unicorn Moonshot AI’s new[Kimi K3 model](https://www.scmp.com/tech/tech-war/article/3361142/why-chinas-open-weight-ai-model-kimi-k3-sparking-anxiety-silicon-valley?module=inline&pgtype=article)rivals top US systems in spotting cybersecurity flaws, according to early research, stoking fears in Washington that strict safety guard rails are putting American[artificial intelligence](https://www.scmp.com/topics/artificial-intelligence?module=inline&pgtype=article)firms at a competitive disadvantage\. The 2\.8 trillion\-parameter open\-weight model, released last week, offers cybersecurity performance “extremely close” to[OpenAI](https://www.scmp.com/topics/openai?module=inline&pgtype=article)’s flagship GPT\-5\.6 Sol at a fraction of the cost, Swiss firm Aikido Security said in a report on Sunday\. Aikido said it tested leading AI models against 26 known vulnerabilities to evaluate bug\-detection rates and cost\-efficiency\. Kimi K3 discovered 23 of the vulnerabilities, matching the performance of OpenAI’s mid\-tier GPT\-5\.6 Terra, while running at a fourth of the cost of the flagship Sol model\. Because the test was private and used recently discovered vulnerabilities, Kimi K3 “was not able to train on them”, Aikido researcher Philippe Dourassov said on social media\. “The performances reflect a very big jump in Kimi models’ capabilities \.\.\. Open\-source models are no longer behind\.” Will China’s new AI model Kimi K3 create another DeepSeek moment? Aikido said Kimi K3 was now the strongest open\-weight model for cybersecurity, “far more capable than” Beijing\-based[Zhipu AI](https://www.scmp.com/topics/beijing-zhipu-huazhang-technology?module=inline&pgtype=article)’s GLM\-5\.2, which was[launched last month](https://www.scmp.com/tech/big-tech/article/3358434/chinas-zhipu-ai-sparks-new-deepseek-moment-cost-effective-coding-model?module=inline&pgtype=article)\.
