More than half of AI Safety Institute assessed models are open-weight, 58 percent Chinese

More than half of the AI models assessed by the AI Safety Institute this year were open-weight, it found. Of 34 unique models assessed from January to August, 19 were open-weight and 15 were closed. Chinese models accounted for 11 of the 19 open-weight models, including Kimi, DeepSeek and Qwen. The institute assesses risks such as prompt injection, data leakage and cyber exploits, but cited limited staff and computing resources.
