Doesn't say much if we don't know what AI you're talking about? The best LLM is far ahead of everything else. If it's GPT-4, translation, editing, proofreading is definitely something to fear.
It's one of the big three. I am deliberately not naming it, because I do not want to steer the conversation into "You clearly should have used LLM X". That's not the point here.
Of course it is. If you say don't worry about x technology and you're not using state of the art then it's meaningless. The "Big 3" is meaningless. The best model is far ahead of the rest.
