Ox Alpha's disguise is finally off: it's Zhipu AI from China! The most mysterious model in the AI world these past few days, Ox Alpha, has just had its identity confirmed by Bloomberg. http://Z.ai (Zhipu) admitted that it's actually the new version of their GLM series, and they’re planning to release the model weights tonight. On August 20, Ox Alpha quietly launched on OpenRouter as an anonymous model, focusing on programming and agents, with 1M+ context length, supporting text, images, and videos—all for free for everyone to use at first. The result? Users had no idea who was behind it but still pushed it straight to the top of the OpenRouter leaderboard. According to Bloomberg, as of the time of reporting, its usage has already surpassed DeepSeek by twofold. Even Stripe CEO Patrick Collison publicly called it “impressive.”
