Model identity leak: Agent reveals itself as GLM via special tokens
zainhas · x · 2026-08-22
A security researcher found that when asking the model 'ox-alpha' to complete text containing the GLM-specific special token <sop>, the model refused, stating that completion would reveal its identity. It subsequently claimed to be a GLM model trained by a specific website, denying development by Zhipu AI, Moonshot, or DeepSeek. This indicates the model retains GLM-specific tokenization characteristics, allowing simple prompts to trigger the disclosure of its underlying architecture.
