ChatGPT doesn’t know present simple?

ChatGPT never makes grammar mistakes itself, when writing. That is truly remarkable, an outstanding achievement. **THIS DOES NOT MEAN THAT IT KNOWS WHAT IT'S DOING AND CAN EXPLAIN IT TO YOU**

it's first attempt at explaining is wrong. the last explanation is correct, it's used as a verb in the past tense.

“I completely understand why that situation upset you” is correct, but its first explanation is inaccurate.

Here’s the thing: chatGPT doesn’t know ANYTHING. It can create grammatically correct sentences by examining its database and predicting (with great accuracy) what word would be likely to come next given all previous words and is such capable of context-dependent content (fancy way of saying it can replicate a conversation). However, it doesn’t KNOW anything and cannot give you a reason for anything it does outside of simply choosing words it thinks would follow such a question. You cannot trust this information whatsoever because it is nothing more than words chosen based on their probability of being next to each other given the context. It is not fact checked or based on actual information.

The sentence using "upset" is correct if past tense. Without context it's hard to know what's going on here.

The thing with ChatGPT and other large language ML model is that they can output something correct (if what you ask them to do is very common across the internet), but the model itself does not necessarily why its output was correct or not, especially if the explanation of such output was not common to see on the internet.

I work analyzing data from AI, the problem with the response is that your input is biased. You’re stating “it should be like this, why is it not”, but the first statement is wrong —in your question you think it should have a -s, but it does not for 2 reasons: grammatical person and tense, the -s is only added for the 3rd person singular in the present tense— so the system ‘thinks’ it is indeed wrong (because you, the human user is saying so), so it ‘thinks’ it has to justify itself and makes up anything to explain it. Maybe it would have explained it better if your input wasn’t biased.

Bold of you assuming this thing can actually know what it's doing

There’s no S on the verb because it’s past tense. “Upset” is an irregular verb and it never changes form: upset, upset, upset. This isn’t present simple; it is past simple, as it said in the final picture. There are a number of verbs like this in English. But AI doesn’t *know* anything, to be clear.

Wow, 'AI' sucks. Who coulda guessed?

Your first guess was correct. "upset" is in the simple past in this sentence. ChatGPT will not make grammar mistakes. But it cannot reliably explain its own choices to you, as (and I cannot stress this enough) it doesn't actually *know* anything. ChatGPT correctly mentioned that "this situation upset you" is a valid past-tense sentence, but it buries this beneath a paragraph of nonsense about "upset" being an adjective, which cannot be true for this sentence.

GPT doesn’t know anything. All it does is produce statistically probably strings. It’s very very good at that. But it doesn’t know why it does anything, and it doesn’t know what truth is or how to tell if something is true. It /cannot be relied on to answer questions accurately/!!! It’s fine to use as a partner in conversation, but it is absolutely not a source for grammatical information.

ChatGPT doesn’t *know* **anything**

Problem is chatgpt writing it in past tense “I can understand why this situation upset you” was supposed to be meant to say “I can understand why you got upset from that situation”. Past tense of upset IS upset not upsetted. It didnt say “this situation upsets you” because probably what you were talking about wasn’t generic and was specific.. specific to an incident of your life that you were explaining to it or specific to how or what chatgpt responded to you “I get upset when my grades are low” Chatgpt : “I can understand why this situation upsets you” (present simple because general fact) “I did not like the way my teacher behaved with me” or “I was really mad when you typed that thing” Chatgpt : “ I can understand why that situation upset you”. Chatgpt was right in the first place. We never use present simple for a specific incident. “The sun rises in the east” (Metaphorically) “That morning the sun rose in the west” Same concept different contexts.

To give another explanation that doesn't mention AI at all: The past tense form of "upset" is "upset".

I believe it's using the past tense which works in the context because the action that bothered you is a completed action in the past. Thus, why it upset you.

It's completely fine.

ChatGPT was correct
