On August 26, 2026, Chinese AI innovator Zhipu officially confirmed that the mysterious Ox Alpha model—which recently surged in popularity on the AI model platform OpenRouter—represents the latest iteration of its renowned GLM series. The company announced plans to release the model’s open-source weights later that evening.

Since its debut on August 20, Ox Alpha has rapidly ascended to the top of OpenRouter’s leaderboard, driven by its zero-cost accessibility and exceptional performance. Its usage volume now exceeds that of DeepSeek by over 200%, a testament to its widespread adoption. The model’s multimodal capabilities—supporting text, image, and video inputs—make it versatile for programming, extended agent-based tasks, and industrial-scale workloads.

Zhipu’s strategy of open-sourcing the model weights aims to democratize access for developers worldwide. By reducing entry barriers, the company seeks to accelerate Ox Alpha’s integration into global AI ecosystems, fostering innovation across industries.
