I'm not an opponent of AI, but I've noticed that some people are using the latest AI for shady race behavior. The video link below shows one such cheater while it replies with a slightly mocking emoticon to the skeptic in the video comments section. As a Chinese I am ashamed. Maybe we don't have an effective way to stop this kind of behavior today, but we shouldn't let this become a trend. Thank you for reading and I hope codeforces staff will do something about it.

Sorry, I'm not really sure if this is the right place to say this, but...
Looks like he deleted the video. But you can still see his humorous submission history on codeforces. especially 10 tries and a compilation error for B
I think they will be removed after plagiarism check, don't be too worried
is this end of cp? I mean literally by using this you could achieve orange performance .. like even graycoder can do that
To be fair, his method of cheating is very easy to spot. He has to submit many different times and each time the code/algorithm is very different.
according to his submission he got E1 in one shot. and btw I believe any careful cheater wouldn't spamming submission like that.
well E1 is a bruteforce weighted graph problem, id be surprised if ai couldnt solve it tbh.
No you can't reach orange with o1-mini atleast. I use o1 everyday, and it's not that good for anything more than div 2A or a mid B/C.
The funniest thing is that he said he ranked above jiangly at about 30 minutes.
Not only did he use GPT to complete the competition, but he even posted a video, did he want to show off? Even exposing his name in his videos, as a cheater, he's stupid enough
The top comment of the vedio "You are the first one I have seen using AI rated for the contest...." is posted by me.
And the vedio auther replied "In the future, AI will definitely enter algorithm competitions in large numbers, and in terms of code, it is completely impossible to determine whether it was written by AI. It can be said that in the next one or two years, online math, programming and other competitions will become a joke. The reason why AI did not have such a great influence before was because AI was not good enough. Now, with the release of O1, the AI field has ushered in another qualitative leap."
Indeed,I can not deny what he said.However, recording and uploading this behavior to public video websites is unreasonable.And it made me both angry and ashamed.
I hope CF can provide a reporting function...
He has just deleted the video. Apparently, he knows what he has done and the result caused by cheating. Such guys should be banned.
