I just tried it. It is an interesting project, but the article exaggerates its intelligence, I think.

First, it is much better in Chinese than in English. It couldn't carry a sensible conversation in English.

In Chinese, I tried many topics, from chitchat, weather, sports to formal conversations in literature, physics, etc. It is much better in chitchat, especially with a tone that is fit for its identity as a young girl. It has many tactics or tricks to cover or change the topics when facing difficulties.

It can't carry formal conversations in literature, physics, etc. although it claims it is good in math and physics. After a few exchanges, it said, "I am sorry. I must look stupid". I continued the topic, and it annoyed "her". This part is built pretty good. It is definitely not knowledge-based A.I.
