We demonstrate that this assumption imposes performance limitations in particular on difficult problem instances.

Recent language models have shown impressive multilingual performance, even when not explicitly trained for it. Despite this, there are concerns about the quality of their outputs across different languages. In this paper, we show how disparity in the treatment of different languages arises at the tokenization stage, well before a model is even invoked. The same text translated into different languages can have drastically different tok-enization lengths, with differences up to 15 times in some cases. These disparities persist even for tokenizers that are intentionally trained for multilingual support.

Humans aren't built for the cold, but have survived frigid temperatures in some amazing cases. Breakthroughs, discoveries, and DIY tips sent six days a week. Winter is not for the faint of heart. In New York City, skyscrapers turn Manhattan into a series of freezing wind tunnels. In Sapporo, Japan, the snowfall is almost 200 inches each winter. Even so, humans have developed plenty of clever ways to wait out the cold. But what would happen if instead of bundling up inside with a hot chocolate, you were left in the frigid cold--just how cold can humans get and recover?

A woman walks near the site of an apartment building hit by a Russian drone strike in Kyiv on Tuesday. KYIV - Ukrainian and Russian officials wrapped up a productive first day of new U.S.-brokered talks in Abu Dhabi, Kyiv's lead negotiator said on Wednesday, as fighting in Europe's biggest conflict since World War II raged on. The two-day trilateral meetings come after Ukraine President Volodymyr Zelenskyy said Russia had exploited a U.S.-backed energy truce last week to stockpile munitions, attacking Ukraine with a record number of ballistic missiles on Tuesday. The work was substantive and productive, focused on concrete steps and practical solutions, Rustem Umerov, the head of Ukraine's National Security and Defense Council, wrote on X. In a time of both misinformation and too much information, quality journalism is more crucial than ever.

Team Mirai leader Takahiro Anno stumps in Tokyo's Shibuya Ward on Jan. 27, the first day of campaigning for the Lower House election slated for Sunday. A small, 9-month-old party that has only one seat in the Upper House may gain as many seats as decadesold peers such as the Japanese Communist Party (JCP) in Sunday's Lower House election with its unconventional campaign pledges to change politics and the government through digital technology. A weekend poll conducted by the Asahi Shimbun showed Team Mirai could win up to 10 seats under the proportional representation system, more than the JCP's nine seats and Reiwa Shinsengumi's six. The party didn't have any seats in the Lower House before its dissolution. The party's founder and leader is a 35-year-old artificial intelligence engineer behind two AI startups -- Takahiro Anno. He had been working on societal reform through digital transformation when he pivoted from business to politics with the launch of Team Mirai last May.

BERLIN - German technology firm DeepL, known for its artificial intelligence-powered translation software, plans to release a Japanese-language version of its real-time interpretation software by the end of this year, a senior company official has said. The age of machine interpretation has arrived, said Leonardo Doin, head of engineering and research for real-time voice translation service DeepL Voice, in a recent interview. You can just wear an earpiece and ... you can just hear it (foreign-language speech) in your language anytime, Doin said. The interpretation software will integrate DeepL's speech recognition and machine translation technologies, and speech synthesis technology that mimics the tones of the speakers' voices. It will be able to handle multiple languages and speakers, he said, with the software's use in online meetings of multinational companies in mind. DeepL plans to roll out the software on smartphones as well.

The USS Abraham Lincoln aircraft carrier, is seen at Naval Air Station North Island in San Diego last August. President Donald Trump reiterated that the U.S. and Iran are maintaining diplomatic talks, even after an earlier skirmish in the Arabian Sea spooked oil markets amid heightened tensions between the two countries. We are negotiating with them right now" and they'd like to do something," Trump told reporters at the White House on Tuesday. They had a chance to do something a while ago and it didn't work out, and we did Midnight Hammer," he said, referring to the June U.S. military strike in Iran. Earlier Tuesday, a U.S. F-35C warplane shot down a drone in self-defense as the unmanned aircraft aggressively approached" the USS Abraham Lincoln aircraft carrier with unclear intent," U.S. Central Command said in a statement. The command said no American service members were harmed and no U.S. equipment was damaged.

Elon Musk attends the 56th annual World Economic Forum meeting in Davos, Switzerland, on Jan. 22. PARIS - French police raided the offices of Elon Musk's social media network X on Tuesday, and prosecutors ordered the tech billionaire to face questions in a widening investigation, amid growing scrutiny of the platform by authorities across Europe. The raid by the Paris prosecutor's cybercrime unit and Musk's summoning -- which could further increase tensions between Europe and the U.S. over Big Tech and free speech -- are linked to a yearlong investigation into suspected abuse of algorithms and fraudulent data extraction by X or its executives. Britain's privacy watchdog, meanwhile, also kicked off a formal investigation into Musk's artificial-intelligence chatbot Grok over the processing of personal data and its potential to produce harmful sexual images and video content.

Without much fanfare, robotaxis have been plying the streets of Tokyo. You can't hail one or order one on an app, and when exactly that will be possible remains a mystery. Nihon Kotsu, the old-school Japanese taxi company running the tests with Mountain View, California's Waymo, isn't saying, and analysts are left guessing. What is clear is that 2026 will be a key year if Japan wants to play catch up, said Mai Niizoe, a senior researcher at Sompo Institute Plus, a Tokyo-based think tank.

Shanghai-based AI startup MiniMax's CEO Yan Junjie (right) and Co-founder and COO Yun Yeyi attend the firm's listing ceremony at the Hong Kong stock exchange on Jan. 9. | AFP-JIJI Hong Kong - Investor confidence in Chinese AI startups is riding high, but obstacles to their long-term success range from U.S. export controls to the puzzle of how to become profitable. This month, two leading players in China's artificial intelligence industry, Zhipu AI and MiniMax, made dazzling debuts on the Hong Kong stock exchange. The pair are part of a wave of rapidly growing Chinese AI tigers spurred by another startup, DeepSeek, whose low-cost AI model, on par with U.S. rivals, stunned the world a year ago.
