So cloude that AI program has this "bug" 
Because all the Chinese data was stolen from deepseek if you ask it in Chinese what model of ai it will answer saying it deepseek. 
But they also stole enough data from chatgpt that if you ask it in French it will say it's a model of chatgpt. 

This comes after the anthompic corporation accused Chinese companies of stealing their data to build better AI models. 

How ironic
