Coder beats AI rival in a win for humanity

A programmer who beat artificial intelligence in a coding competition has declared that “humanity has prevailed (for now!)”.
Przemyslaw Debiak, known as Psyho, said he was “completely exhausted” and “barely alive” after winning the At- Coder World Tour Finals in Tokyo.
Debiak beat an advanced and specially trained AI model from OpenAI, the company behind ChatGPT — for which he used to work. Sam Altman, the chief executive of OpenAI, was gracious in defeat, posting on X that Debiak had done a “good job”. The company added: “Congrats to the champion for holding us off this time.”
Debiak, 41, was competing in a contest where the goal was to write a program that guided robots across a grid using the fewest possible moves. He said that he only had ten hours of sleep in three days, adding on X: “Honestly, the hype feels kind of bizarre. Never expected so many people would be interested in programming contests.”
The Polish programmer’s victory, which comes with a 500,000 yen (£2,500) prize, will be some reassurance to those who fear for the future job prospects of coders.
AI coding has become one of the hottest areas of the technology. Cursor, which provides AI for programmers, has become one of the fastest growing start-ups in history. More than half of Fortune 500 companies use its services.
Leading companies in the field are also seeking to buy AI coding start-ups such as Windsurf, which had a turbulent few days last week. OpenAI had been expected to buy the company, but the deal fell apart, then Google hired Windsurf’s chief executive and other senior staff, and a rival AI start-up bought what was left.
AI coding has also enabled non-technical people to create software through text prompts, leading to a new trend called “vibe coding”. This year’s AI Index Report from Stanford University said that on one benchmark, AI systems could solve just 4.4 per cent of coding problems in 2023, but by last year that had jumped to 71.7 per cent.
Andrej Karpathy, the OpenAI cofounder, said in 2023, after the launch of ChatGPT: “The hottest new programming language is English.”
Debiak told Business Insider that in cases that require straightforward engineering, AI would beat humans. But in longer contests where programmers do everything from scratch, AI had a harder time. “The longer the contest is, the more chances for humans and less chances for AI,” he said.
A recent study from METR, a research group in California, found that while developers believed using AI tools helped them to perform 20 per cent faster, they actually worked 19 per cent slower. One factor was that human developers found AI-generated code unreliable and ended up devoting extra time to reviewing, testing and fixing it.
But the authors warned that AI coding tools were rapidly improving, so their findings could soon be out of date.
Debiak’s victory is the latest contest pitting humans against machines.
Garry Kasparov, the world chess champion, played two matches against IBM’s computer Deep Blue in 1996 and 1997, winning the first but losing the second. In 2016 an AI program developed by DeepMind called AlphaGo beat the Go world champion, Lee Sedol.
