Chinese AI firm Z.ai, also known as Zhipu, confirmed to Bloomberg it developed the Ox Alpha AI model. The model recently topped performance charts following an anonymous stealth release on platforms like OpenRouter.
Ox Alpha impressed developers and tech executives with high performance in coding and reasoning tasks. Z.ai plans to release the model's weights to make it open-source.
Anonymous releases allow Chinese firms to test models in real-world environments before official announcements. This strategy helps domestic companies compete with major U.S. AI labs.
