Human beats AI in Tokyo coding contest!

Hans India6 days ago
Tokyo: Atthe 2025 AtCoder World Tour Finals' Heuristic Challenge held in Tokyo, renowned coder Przemysław Dębiak — widely recognized in the programming world as 'Psyho' and a former member of the OpenAI team — edged out the specially designed AI model in a tightly contested battle. Hosted in Tokyo by the esteemed Japanese competitive programming site AtCoder, this year's grand finale introduced a unique twist — a 'Humans vs AI' showdown. Considered the pinnacle of invitation-only programming competitions, this elite tournament welcomes just 12 of the highest-ranked coders annually, chosen through rigorous qualification criteria.Spanning 10 hours, the event tasked participants with tackling one exceptionally difficult optimization problem—completely unaided, with no access to libraries, documentation, or outside help. Though the AI took an early lead, Dębiak ultimately overtook it. Although AI initially pulled ahead, Dębiak eventually surpassed it by drawing purely on his instincts, creativity, and deep expertise. Fellow coder Stanisław Eysmont commented, 'Przemek succeeded without pre-built tools, without reference materials, and without any guidance.'
'I was so tired. I actually felt at some point that I should take a break,' Dębiak, who competed under the name 'Psyho,' told the reporters. 'But at the same time, I was very close to getting a score comparable to the model,' he added. In a historic first, the contest opened its doors to an AI competitor, with OpenAI not only sponsoring the event but also entering its custom AHC model as an official participant. To ensure fairness between human participants and the AI system built by OpenAI, AtCoder supplied standardized hardware to all contenders. The rules of the tournament allowed the use of any programming language supported on the AtCoder platform, and there were no penalties for incorrect submissions. Dębiak was also instrumental during his tenure at OpenAI, serving as one of the pioneering engineers behind OpenAI Five—the AI system that famously triumphed over professional Dota 2 players in 2019. In a post shared on the social media platform X, OpenAI CEO Sam Altman acknowledged Dębiak's win and wrote, "good job Psyho." OpenAI also publicly recognised its tool's performance on X, stating, "Our model took 2nd place at the AtCoder Heuristics World Finals! Congrats to the champion for holding us off this time."

China PM warns against a global AI 'monopoly'

China PM warns against a global AI 'monopoly' China will spearhead the creation of an international organisation to jointly develop AI, the country's premier said, seeking to ensure that the world-changing technology doesn't become the province of just a few nations or companies. Artificial intelligence harbours risks from widespread job losses to economic upheaval that require nations to work together to address, Premier Li Qiang told the World Artificial Intelligence Conference in Shanghai on Saturday. That means more international exchanges, Beijing's No 2 official said during China's most important annual technology summit. Li didn't name any countries in his short address to kick off the event. But Chinese executives and officials have taken aim at Washington's efforts to curtail the Asian country's tech sector, including by slapping restrictions on the export of Nvidia chips crucial to AI development. On Saturday, Li acknowledged a shortage of semiconductors was a major bottleneck, but reaffirmed President Xi Jinping's call to establish policies to propel Beijing's ambitions. The govt will now help create a body - loosely translated as the World AI Cooperation Organization - through which countries can share insights and talent. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The Most Beautiful Female Athletes Right Now Undo "Currently, key resources and capabilities are concentrated in a few countries and a few enterprises. If we engage in technological monopoly, controls and restrictions, AI will become an exclusive game for a small number of countries and enterprises," Li told hundreds of delegates huddled at the conference venue on the banks of Shanghai's iconic Huangpu river. China and the US are locked in a race to develop a technology with the potential to turbocharge economies and - over the long run - tip the balance of geopolitical power. This week, US President Donald Trump signed executive orders to loosen regulations and expand energy supplies for data centers - a call to arms to ensure companies like OpenAI and Google help safeguard America's lead in the post-ChatGPT era. At the same time, the breakout success of DeepSeek has inspired Chinese tech leaders and startups to accelerate research and roll out AI products. The weekend conference in Shanghai - gathering star founders, Beijing officials and deep-pocketed financiers by the thousands - is designed to catalyze that movement. The event, which has featured Elon Musk and Jack Ma in years past, was launched in 2018. This year's attendance may hit a record because it's taking place at a critical juncture in the global race to lead GenAI development. It's already drawn some notable figures: Nobel Prize laureate Geoffrey Hinton and former Google chief Eric Schmidt were among heavyweights who met Shanghai party boss Chen Jining Thursday, before they were due to speak at the event.

Sathiyan-Akash wins; Sreeja loses in final

G. Sathiyan and Akash Pal beat Jules Rolland and Leo De Nodrest of France 11-9, 11-4, 11-9 to win their maiden Tour men's doubles title at the WTT Contender Lagos on Saturday. This is Sathiyan's second WTT men's doubles title overall. 'Fantastic. We both were unseeded. Still, to beat the French pair by a 3-0 margin was great. We combined well. Akash has a powerful game, and I could place the ball well. We complemented each other,' Sathiyan told The Hindu. Sreeja Akula's confidence would have been sky high going into the women's singles final. She had beaten the likes of top seed Hina Hayata (first round), seventh seed Jieni Shao (quarters) and fourth-seeded Prithika Pavade in the semifinals. However, Japanese second seed Honoka Hashimoto beat Sreeja 11-7, 11-3, 11-4, 9-11, 13-11 in the summit clash to clinch the crown. Other results: Women's semifinals: Sreeja bt Prithika Pavade (Fra) 11-7, 11-4, 11-13, 6-11, 11-9; Mixed doubles final: Jules Rolland & Pavade (Fra) bt Akash Pal & Poymantee Baisya 12-10, 11-6, 6-11, 11-7.=

Sreeja Akula loses women's singles final at WTT Contender Lagos; Sathiyan-Akash pair secures men's doubles title

Indian paddler Sreeja Akula ended her women's singles campaign at the WTT Contender Lagos as runner-up after losing 1-4 to Japan's Honoka Hashimoto in the summit clash on Saturday. In the 48-minute final, Hashimoto put considerable distance between herself and Sreeja after winning the first three games 11-7, 11-3, 11-4. However, the Indian opened her account and clinched the fourth game 11-9 to remain in the contest. The fifth game saw Sreeja start well but the Japanese player stayed close to her opponent. Sreeja led at 10-9 but Hashimoto held on to equalise and eventually seal the game 13-11, and consequently the match. The 26-year-old Indian had beaten France's Prithika Pavade 11-7, 11-4, 11-13, 6-11, 11-9 in a semifinal clash which lasted 39 minutes. Earlier in the day, Indian duo of Gnansekaran Sathiyan and Akash Pal beat France's Leo de Nodrest and Jules Rolland in the final to win the men's doubles title. The pair secured the title in under 22 minutes, beating its opponents 11-9, 11-4, 11-9.
