GPT-4 can translate text in different languages. GPT is great for working with text.
Unless the content might be sensitive or even offensive to some people, then GPT may refuse to cooperate.
I once saw people talking about a song made during the war in Ukraine, and wanted to know what the lyrics are about. It refused to translate.
I tried to convince it I'm seeking the information for educational purposes, would not spread it, and am aware fighters on both sides are human beings, yet it refused.
A less sophisticated tool gave me a fairly understandable translation (as far as I can tell, unable to understand the original), but then I could not ask how certain things might be meant.
I like to be able to follow up with questions for the given context with ChatGPT, but experiences like these have deterred my quite a bit from using and recommending it. I'd like to decide when I want to use a tool, and do not want the tool to overrule my decision.
I heard similar experiences from people trying to use it to write fantasy or sci-fi.
You specifically refered to the payment as one of 3 causes of this (someone else's model and hardware, no payment). That is wrong, paying them does not change that. Notice how your reply makes it seem like I talk about the other 2 causes, I don't.
Not to mention - taking about your own model is totally absurd. That is like suggesting to someone who dislikes touchscreens in cars to build their own car.
Its information is often wrong, and not only that, it provide legitimate looking fake links also if you ask for source. Even if you ask it for school level maths, it does it wrongly.
For simple things it might ne providing good enough info, but I still wouldn't trust it at all.
Choose any topic where you are sufficiently proficient and ask it questions about it.
Asking it to directly do math is simply the wrong approach. Like using a car to paint lines on a road. It kind of can do it, but not really. You can ask it for instructions how to do the calculation or for code that does it. Or get the GPT Wolframalpha plugin and let that do it directly.
Seems like the results are hit and miss. I don't know why. I never thought much about how I please something, but maybe it does matter and I just happen to do it right?
