Can't argue with that, I'll move my Bayesian's a little in your direction. With that said, are most other models able to do this? Also, did it write the solution itself or use a library like Eigen?

I have noticed that LLM's seem surprisingly good at translating from one (programming) language to another... I wonder if transforming a generic mathematical expression into an expression template is a similar sort of problem to them? No idea honestly.

It wrote a solution by itself, from the scratch, with dozens of little type traits, just as I would do. Really clean code. And the problem at hand is not the mathematical, linear algebra one. I gave that example just for easier understanding of the problem at hand. The problem is actually about the high-performance serialization. Finally, I instructed it to build complex test cases with multiple levels of nested computations to really check whether we are making any copies or not. Did it in a breeze.

Not sure about the other models. I'd guess that Claude would do equally good but I don't have the subscription for other models so I can't really compare. I for sure know that the ones from the free-tier are not worth spending time with for tasks like this. I use them mostly for one-shot questions.

So yeah, I think I have a pretty good experience. Not perfect definitely but still looks like a SF to me. Even to a highly trained C++ expert it would take probably like a day to build something like this. And most C++ folks wouldn't even know how to build this.
