SUMMARYOpenAI is set to compete again against human heuristic programmers at the AtCoder World Tour Finals 2026 in two days, renewing a matchup that previously saw Przemysław Dębiak, known as Psyho, defeat OpenAI’s custom system last year. The event centers on algorithmic optimization and could feature a new OpenAI model, but no results are known yet.
Psyho, aka Przemysław Dębiak, is widely seen as one of the greatest heuristic programmers ever, a former early OpenAI employee, and the guy who beat OpenAI’s custom AI system at last year’s AtCoder World Tour Finals, with the AI finishing second.
Now AWTF 2026 is happening in two days, and OpenAI is back for another Human vs AI match. No idea what they’ll bring this time, maybe GPT-5.6 Pro, maybe some unreleased internal monster.
Either way, this feels like one of those rare events where you can actually watch the frontier move in real time. Human intuition, optimization wizardry, and whatever OpenAI has been cooking, all in the same arena. Very hard not to be hyped for this.
On the other hand, one might ask yourself why in 2026 OpenAI decided to compete again vs humans. In 2025 they had a very strong result in IMO, got the 2nd place at AWTF heuristic and solved all of the problems at the ICPC. That would be a huge narrative violation if in 2026 they didn't easily win, right? Considering this, I expect that OpenAI put some actual effort into it and this is not just the same thing they did in 2025 with a stronger underlying model.
