Ox-Alpha Is GLM?

OX Alpha, a mysterious new model appearing on OpenRouter, has been reverse-engineered and identified as GLM, developed by Z.ai, despite its system prompt claiming to be from an "undisclosed organization." Researchers used prompt injection techniques to extract the system prompt and gzip-NCD compression analysis to reveal the model's true identity, though initial speculation had suggested it was a Google Gemini model based on activity from Google employees.
