Polish programmer Przemysław Dębiak, also known as “Psyho” on the web, has achieved an unprecedented feat: he beat OpenAI’s artificial intelligence in one of the world’s toughest programming competitions. OpenAI is the creator of ChatGPT, an advanced AI model.

In the AtCoder World Tour Finals 2025 (Heuristic Division) held in Tokyo earlier this month, Dębiak clinched the top spot, leaving a customized algorithmic model from OpenAI trailing in second place. This exclusive competition assembled 12 of the world’s top programmers, who were handpicked based on their global rankings.

The gap between Dębiak’s final performance and that of the OpenAI model widened from an initial 5.5% to a decisive 9.5%, clearly demonstrating his superior skills.

“He’s a low-key individual who takes immense satisfaction not just from winning, but also from outperforming a system he helped create,” his friend Stanislaw Eismont, a technology consultant, told Euronews Next. Dębiak was previously an employee at OpenAI.

A Grueling Global Contest

The contest spanned ten hours and involved solving highly intricate code optimization problems. Participants were tasked with tweaking existing code snippets to enhance their speed and efficiency to the maximum extent possible.

Following the competition, Dębiak posted on Platform X: “I am completely drained. I’ve barely slept ten hours over the past three days and I feel like a specter.” Earlier, he had posted: “Humanity has triumphed (for now)!”

His impressive performance even garnered commendation from OpenAI CEO Sam Altman, who messaged him on X: “Good job, psyho.”

Aismont noted: “It was a grueling ten-hour marathon. No instructions, no documentation, no prompts. A genuine optimization problem, with no ‘correct’ solution – only ones that were better than the rest. In this high-pressure, strategic environment, Przemek stood out. And he won. He even outperformed the artificial intelligence.”

The AtCoder final is globally recognized as the premier event in the realm of algorithmic optimization. The challenges that the contestants face blend advanced algorithmics, statistics, computational theory, and creative thinking.

“I’ve never had a Blueprint for Life”

Born in 1983 in Gdynia, Poland, Dębiak has a distinguished history in programming competitions, boasting numerous awards. He is a member of Mensa and a multiple-time Polish champion in puzzle and logic problem-solving.

In an Ask Me Anything (AMA) session on the Polish platform Wykop, he shared several personal details:

  • He has never worked a traditional 9-5 job.
  • He didn’t complete his university education and only has a high school diploma.
  • As a child, he dreamed of becoming a superhero.
  • He admits to never having a set “blueprint for life” and has contemplated careers as a game developer, actor, DJ, or professional poker player.
  • He currently resides in Poland and has no plans to relocate.

However, his victory this year appears to be opening up new opportunities. As Aismond noted, major tech companies are keenly observing the event as they consider it “an indicator of who truly understands the thought process behind coding.”
