I have deeply reflected on my actions, and I realize that using AI in rated competitions under any circumstances is inherently wrong. I acknowledge that this behavior is inappropriate and regret posting a video on social media to boast about using AI. I promise never to use AI in algorithm competitions again.

After the release of OpenAI's new O1 model, I repeatedly attempted to use it for coding, particularly on Codeforces, where its effectiveness was especially noticeable. Taking Div2 as an example, after multiple attempts, I found that the O1 model could achieve a ranking of around the top 500 (at least in terms of the number of problems solved, no one in our university could reach this level). For an student who had never achieved such a milestone, this temptation was considerable. Therefore, I immediately signed up for a competition, aiming to use AI to solve problems as quickly as possible.** At the 42-minute mark, I solved problem E1 and climbed to the tenth position**. This left me both shocked and excited. Although I made no further progress on subsequent problems, my ranking remained high and increased significantly. In this state of excitement, I posted a video boasting about using AI. However, at the time, I did not understand the implications of my actions. In hindsight, it was truly foolish and ignorant, and I formally apologize to everyone.

Looking ahead, AI will undoubtedly enter algorithm competitions in large numbers; this is just the beginning. The fact that merely a few uses of AI models had such a significant impact indicates that AI's future advancements are immeasurable. In terms of code, it is completely impossible to determine whether it was written by AI because, at least on the Codeforces platform, 90% of the competitors, including myself, are not as strong as AI. It can be said that in the next one or two years, online math, programming, and other competitions may lose their original seriousness. The reason AI did not have such a great influence before was that it was not powerful enough, but now, with the release of O1, the AI field has ushered in another qualitative leap.
