Claude vs ChatGPT: Which is the Best?

To know the actual capabilities of both ChatGPT and Claude, we did some tests on both of the AI technologies. So we can know the actual performances of both LLM models rather than trusting the theoretical values of each model, and here is what we found.

Test 1: Coding 

I am not a coder and do not even know much of the basics of computer languages. But everyone wants to play and create games, and that is exactly what I did with these LLM models. I asked them to create a chess game following all the rules on both ChatGPT and Claude. 

I asked Claude to create a chess game that I can actually play. In its artifacts feature, at first, it was able to create, but it didn't follow any chess rules. When I tweaked the prompt to make it follow chess rules, it displayed that it can only write programs, not run them. However, when I tested it, it worked fine on a compiler. But ChatGPT straight away gave a no answer. Here are the results.
