Forth user here.

Don't use AI, it writes Forth like it writes C. It has got better at following Standard, in Gforth style, but it is awful at the spirit of Forth: factoring programs into a vocabulary of tiny, reusable pieces.

I posted a Forth programming challenge. I was very disappointed to get two AI answers and one human. I think the humans sussed out the solution and described an algorithm to Opus, but, the AI strategy produced one large page-filling word.

A top-level word filling one page, doing everything there except some subroutines mimicking C Standard Library.

In Forth, that chunk ought to be many smaller words. Heck, even in C (at least it fit in a page.)
