Estimating Guowang Internet service satellite mass with ChatGPT

After searching for the mass of China's Guowang Internet-service larger satellites and finding nothing, I estimated it using ChatGPT. Since I knew the number of satellites (10) and the rocket used (Long March 5B) in two launches, the mass of a single satellite could be estimated if I knew the carrying capacity of the rocket.

I asked ChatGPT this question five times: How much mass could a Long March 5B rocket with a Yuanzheng-2 (YZ-2) upper stage carry to 1,100 kilometers with an inclination of 86.5 degrees? The average answer was 16.6 tonnes or 16,600 kg.

ChatGPT's five answers and the "reasoning" that led to them can be found here. Each is different --  ChatGPT does not remember prior submissions of the same question. I am not a rocket scientist and can only average the five results in estimating the satellite masses. I'd like to know what experts think of the results and the reasoning leading them.

There have been four launches of smaller satellites, and so far, 889 kg is a rough estimate of their average mass.
