Ox Alpha is identified as the GLM 5.3 Flash model released by zAI.

Ox Alpha, identified as Zai's GLM Flash, is announced to be released tonight.

According to rumors, a certain new model from zAI is at least as strong as Fable 5 in cybersecurity capabilities, but information is limited, only citing a Wall Street Journal article discussing GLM 5.2.

Sentdex reports that GLM 5.2 from Zai is the first open model that can replace GPT-5.5 and Opus 4.8 across many tasks, with strong coding and agentic performance and a 1M context window.
