The cow comes home: China’s Internet celebrates Z.ai claiming ownership of Ox Alpha (www.businessinsider.com)

China's Z.ai lab has officially claimed ownership of the recently unveiled Ox Alpha model, which was initially a free preview of their GLM-5.3-Flash AI model. After its introduction on OpenRouter and OpenCode, Ox Alpha quickly gained popularity, becoming the most-used model of the week and generating significant buzz among Chinese internet users, particularly on Weibo. The model has been celebrated for its strong performance at a low cost, showcasing advancements in domestically produced AI chips that can efficiently support large-scale applications. The significance of Ox Alpha lies in its representation of Chinese open-source AI's growth and competitiveness in the global market. With endorsements from both local users and international tech executives like Stripe's CEO Patrick Collison, the model underscores a shift in the perception of Chinese AI capabilities. The enthusiasm surrounding Ox Alpha not only highlights the innovation within China's AI scene but also reflects a larger trend of Chinese models, such as Moonshot AI's Kimi K3 and Alibaba's Qwen3.8-Flash-Next, gaining traction in an increasingly competitive field, potentially rivaling those from established players like OpenAI and Anthropic.
