“Human Coder Clinches Victory Over AI in Tokyo—A Final Triumph

Polish coder Przemysław Dębiak, aka “Psyho,” edged out OpenAI’s algorithm at the 2025 AtCoder Finals in Tokyo. Despite the win, he cautions it may mark the last human victory as AI outpaces humans in speed and problem-solving.

“Human Coder Clinches Victory Over AI in Tokyo—A Final Triumph

Despite sweeping victories in games like chess, Go, and poker, artificial intelligence has yet to dethrone top human talent in one highly technical domain: competitive coding. This month’s AtCoder World Tour Finals 2025, held in Tokyo, witnessed Polish mind sports champion Przemysław Dębiak better known as “Psyho” narrowly outscoring OpenAI’s algorithm to claim the coveted title.

The contest featured a 10-hour marathon of optimization problems, including classics like the Travelling Salesman challenge, where participants seek the shortest route through a set of cities without revisiting any. AI models are celebrated for their speed and brute-force computation in such tasks, but nuanced logic and strategic intuition gave Psyho the edge, beating the algorithm by 9.5%.

“I tweeted ‘live by the sword, die by the sword’ before the match,” Psyho said, referencing his ironic role in developing AI at OpenAI before retiring five years ago. “Although I won, in the end, for now.”

The heuristic division of the tournament drew 11 top human coders based on global rankings. Psyho—aged 41 and a veteran of AI development—acknowledged this victory might be humanity’s last stand. “I would prefer not,” he said of losing the title to AI, “because I like these competitions and knowing there’s this magical entity that can do it better than me would be a little bit frustrating.”

OpenAI’s CEO Sam Altman tweeted his congratulations, a nod to the increasingly blurred boundary between machine learning and creative problem solving.

Still, Psyho noted that humans are “bottlenecked” by how quickly they can type code, whereas an AI can test thousands of minor tweaks simultaneously. “The model is like cloning a single human multiple times and working in parallel,” he said. “AI might not be the smartest right now, but it’s definitely the fastest.”

The broader industry trend backs his concern. Meta, Microsoft, and others have begun shifting software development tasks to AI, and Anthropic CEO Dario Amodei predicted in May that 20% of white-collar jobs could be absorbed by AI within five years.

“Every profession has this right now, more or less,” Psyho commented. “For manual jobs, robotics is lagging by several years.”

He remains ambivalent about the pace of AI’s advancement. “We have a tonne of issues,” he warned. “Disinformation, social impact, humans not having a purpose in life. Historically, society moves at a very slow pace. Technological progress right now is moving at a faster and faster and faster pace.”
