My friend Away_in_the_heavens sent me a screenshot that left me completely shocked.

I have never seen anything like this on the platform before:

The image shows the standings of today’s round.

For comparison, here's what standings typically looked like across 100 previous contests:

Of course, incidents of unfair play have happened before. However, judging by today’s round, the number of cheaters has increased tenfold, if not a hundredfold. And the reason is clear — the appearance of tools like ChatGPT o1 or ChatGPT mini-high-3, which are apparently capable of solving problems up to ~3000 rating in just a few minutes.

As a result, the round turns into a minigame for cheaters: who can type faster or debug ChatGPT's solution more efficiently.

In my opinion, the current state of affairs calls for action. Perhaps it's time to reconsider the rating system or implement new mechanisms to address such violations.

I’d love to hear the thoughts of both the Codeforces team and veteran users who have been on the platform for many years.
