From https://openai.com/index/learning-to-reason-with-llms/:
We trained a model that scored 213 points and ranked in the 49th percentile in the 2024 International Olympiad in Informatics (IOI), by initializing from o1 and training to further improve programming skills. This model competed in the 2024 IOI under the same conditions as the human contestants. It had ten hours to solve six challenging algorithmic problems and was allowed 50 submissions per problem.
For each problem, our system sampled many candidate submissions and submitted 50 of them based on a test-time selection strategy. Submissions were selected based on performance on the IOI public test cases, model-generated test cases, and a learned scoring function. If we had instead submitted at random, we would have only scored 156 points on average, suggesting that this strategy was worth nearly 60 points under competition constraints.
With a relaxed submission constraint, we found that model performance improved significantly. When allowed 10,000 submissions per problem, the model achieved a score of 362.14 – above the gold medal threshold – even without any test-time selection strategy.
Finally, we simulated competitive programming contests hosted by Codeforces to demonstrate this model’s coding skill. Our evaluations closely matched competition rules and allowed for 10 submissions. GPT-4o achieved an Elo rating3 of 808, which is in the 11th percentile of human competitors. This model far exceeded both GPT-4o and o1—it achieved an Elo rating of 1807, performing better than 93% of competitors.
This is so much more impressive than I thought would be achieved even in the next 4 years.
So to make it clear what models have what:
https://openai.com/index/learning-to-reason-with-llms/
https://openai.com/index/openai-o1-mini-advancing-cost-efficient-reasoning/
The strongest model, o1-ioi, was fine tuned on competitive programming problems. 1807 rating. Not available to the public at the moment.
The next strongest model is o1, 1673 rating. Not available to public.
o1-mini is publicly available and 1650 rating.
o1-preview is publicly available and 1258 rating.
The naming is kind of confusing, because o1-preview would be expected to be stronger than o1-mini, but o1-mini is actually the strongest.
Time to massively overhaul the cheating detector... or prepare for some insane rating inflation.
I don't think using AI is even considered cheating currently...
Yeah I'm thinking it's not just about having the AI literally spit out the full solution.
"Hey ChatGPT, here's a problem statement, what algorithm should I use to solve it?" would allow a (current rating system) 1000-level to solve 1800-level problems. It might even allow a 2000-level to solve 2800-level problems by reducing the search space — even if an AI's rating is 1800, it can still help a human do better on harder problems. Of course, it's 1800 now, maybe it will be 4800 soon?
And there's really nothing we can do about it, it will just force programming contests to evolve in some way. With some possibility that online contests will become completely useless. (But we are not there yet)

i guess my 1600 is not so special anymore
It was never very frankly...neither is mine :/
at least it felt good achieving a blue rank back then :(
cmon PrakharJain heavenly_, what sort of pity fest is this? You guys are doing well; keep up the good work.
The article says we are releasing an early version of this model, OpenAI o1-preview, for immediate use in ChatGPT and to trusted API users, so the 1258 rating ver. is coming soon.
I can imagine a day when I wake up, only to read the news that I basically have lower rating than a bot.
i already woke up to this
This happened to me before bots existed.
That already happened in Chess long back. Before that no one thought a bot can hit GM level. It will eventually come up to cp too it's just a matter of time.
this happened to me today :(
This is concerning
We are all doomed :/
It will not take away your ability to enjoy solving problems.
But no one enjoys solving problems when they starving..hehe, just kidding....or..?
i have neetbux
well, fuck
Maybe o1-ioi handle is Scripted1234?
no this seems to be genuine profile unless they used his name
So my dreams of becoming an expert is gone?
It would've been great to get more information about the IOI performance — especially how the 362.14 score was distributed, how the code looked, and what kind of training was put on top of o1 to produce o1-ioi (and whether that was unbiased)
Maybe I am wrong, but even with unlimited number of submissions I find gold at the IOI extremely impressive compared to 1800 on Codeforces.
We will find out soon. Hackercup starts in 7 days and allows LLM submissions, so we no longer need a custom environment that may or may not be biased.
Agreed.
I agree, also I wish OpenAI was more transparent (it has 'open' in the name...). How are we living in a world where Mark Zuckerberg is releasing the best open source AI models?:))
This model is constrained because of the inference cost, so this rating should be viewed as lower bound of what's possible. Highly likely that iterating for longer time during reasoning is going to produce even better results. Would be fun to see an actual paper showing if it's true and if it is what are the diminishing returns related to the time spent during reasoning.
Sadly, the days are not far when a bot will overtake the Masters. More thing to worry is that these models (o1-mini) are available to public.![](/predownloaded/ce/9e/ce9e9a538a08d953ea9641b994b31ef38cb7395f.png)

training on test is all you need!
Are the CF contest submissions public?
I would say that the google model that got a silver model at IMO was much more impressive than this
Well, it abused the modern ways of solving geometry(Wu method). As far as I remember the model is still not capable of solving any IMO-level combinatorics task
Did someone make a test to confirm that the public o1-mini can actually solve problems up to 1650 rating as claimed?

This is crazy. Maybe the end of online competitive programming era.
Some users may argue this is not a big deal, using GO as example. In the Go game, the AI beat world rank 1 player Jie Ke very hard in 2017, does Go die? No, because in the real competition, players cannot use AI.
However, in codeforces, all players are competing offline, which means you don't know if he or she is cheating or use AI. Imagine you are an expert, in a div2 round, you solve 2A and 2B in 15 minutes. Then you discover that you have already rank 10000+, because many many newbies just copy the problem statement, paste to chatGPT and solved up to 2D, both 2C and 2D has 10000+ accepted users. How do you feel?
It just like you are top runners in Marathon race, many cheaters just ride the motorcycle to finish the race in 30 minutes, break the world record, and the committee just say their result is effective, you rank behind them.
I can solve the problems just for fun, but cheaters will not. And it is not fun if cheaters beat me every time I participate, and make my rating drop from master to newbie.
It's time for codeforces official to do something do handle this situation. I am serious.
i'm also not sure what they mean by "simulation" of contest, did o1 participate in latest contests with unique problems?
did they make sure that codeforces problemset and solutions are not in the training data?
