This competition will feature 17 free AI models competing against each other, with the top three strongest AIs ultimately selected.
Competition Format
- Qualifier Round: Select 8 AIs from the total of 17. Starting with Codeforces problems rated
*800, the difficulty increases progressively to eliminate participants until no more than 8 AIs remain. The remaining eliminated AIs can participate in a challenge round; if they successfully solve a problem rated*2100, they earn one resurrection chance. - Knockout Round: After the qualifiers, the 8 AIs engage in one-on-one PKs with progressively increasing difficulty. The first AI to provide an incorrect answer is eliminated. If an eliminated AI has a resurrection chance, it can consume one to advance to the next round alongside the winner.
- It is evident that the knockout round will consist of at least 3 rounds and at most 4 rounds.

not sure if they are giving real responses but you can ask the *AIs which model they are, claude says its Claude 3.5 Sonnet
Thank you. Qualifier Round is running. I think it will finish soon. (But I at least need to wait to tomorrow)
Yeah you should probably use fable.
Also fable will probably lay waste to anything <=2400 and probably can solve well into the 3000s, it did do a minor screwup on a 2600 once though https://codeforces.me/contest/2246/submission/382324400
So its actually your alt, why does it say "definitely not my alt" >:(
Alright I clicked that one without thinking I have to give it to you
hehe :D
Okay, Thank you. It will appear as special guest to jion this. But i couldn't register Cluade XD. So would you like to judge it and send the result to me?
