Somehow we went from writing software apps and reading API docs to research level astrophysics

Sure it's not there yet. Give it a few months

It doesn't even work for basic astrophysics

I asked chatgpt the other day:

"Where did elements heavier than iron come from?"

The answer it gave was totally wrong. Its not a hard question. I asked it this question again today, and some of it was right (!). This is such a low bar for basic questions
