This was supposed to be an article comparing three major AI players in their ability to write technical articles. In preparation, however, I made some mistakes ... :(
When I prepared for the initial article, I asked them to fetch the data from https://github.com/gabr42/ComputeCore/blob/main/ComputeCore.pas and write about it. (See the end of this article for the initial query and results.) At that moment, however, that link was not public yet. All three AIs ignored that and happily wrote about the code they knew nothing about. It was only Claude that complained about the bad link but I missed that while checking the results.
So I decided to rerun the experiment on all platforms. I started by asking the engines the following question:
Can you accesss https://github.com/gabr42/ComputeCore/blob/main/ComputeCore.pas and provide an overview of the code in one paragraph?
Can you accesss https://raw.githubusercontent.com/gabr42/ComputeCore/refs/heads/main/ComputeCore.pas and provide an overview of the code in one paragraph?
Analyzing the answer shows that the answers were not done purely on the basis of the linked code. Both Claude and Gemini have included details that they got from my previous article on ComputeCode.
In the answers below I marked hallucinated misinformation with red and information that was obviously retreived from different sources with blue.
