It integrates GPT-4o into a .NET app - the article is fine. Lemmy just doesn't like it being injected into everything (even when it could improve the UX, because "can't give them an inch" or something implied).
This article isn't a grift, just a simple tutorial. Nothing to be mad about.
edit: OP, maybe next time specify which AI is being used instead of using the nebulous "AI" term.
