Mysterious 'OX Alpha' Model Outperforms GPT-5.6 in Coding Tests

An anonymous AI model, 'stealth/ox-alpha', appeared on OpenRouter and OpenCode, scoring 80% on DeepSWE coding tests, surpassing Claude Fable 5 and GPT-5.6 Sol. While independent researcher Ben Davis suspects it originates from Zhipu AI's GLM-5.x, the creator remains anonymous and official confirmation is pending.
