It would be more interesting to make it build a chess engine and compare it against Stockfish. The chess engine should be a standalone no-dependencies C/C++ program that fits in NNN lines of code.
It will lose so badly there will be no point in the comparison.
Besides you could compare models (and harnesses) directly against eachother.
Maybe that's the result you want for some sort of rhetorical reason, but it would nonetheless not be an informative test.
