Chinese tech company Alibaba on Wednesday released a new version of its Qwen 2.5 artificial intelligence model that it claimed surpassed the highly-acclaimed DeepSeek-V3, Reuters reported.

The unusual timing of the Qwen 2.5-Max's release, on the first day of the Lunar New Year when most Chinese people are off work and with their families, points to the pressure Chinese AI startup DeepSeek's meteoric rise in the past three weeks has placed on not just overseas rivals, but also its domestic competition.

"Qwen 2.5-Max outperforms ... almost across the board GPT-4o, DeepSeek-V3 and Llama-3.1-405B," Alibaba's cloud unit said in an announcement posted on its official WeChat account, referring to OpenAI and Meta's most advanced open-source AI models.

The Jan. 10 release of DeepSeek's AI assistant, powered by the DeepSeek-V3 model, as well as the Jan. 20 release of its R1 model, has shocked Silicon Valley and caused tech shares to plunge, with the Chinese startup's purportedly low development and usage costs prompting investors to question huge spending plans by leading AI firms in the United States, read the report.

But DeepSeek's success has also led to a scramble among its domestic competitors to upgrade their own AI models.

Two days after the release of DeepSeek-R1, TikTok owner ByteDance released an update to its flagship AI model, which it claimed outperformed Microsoft-backed OpenAI's o1 in AIME, a benchmark test that measures how well AI models understand and respond to complex instructions.

This echoed DeepSeek's claim that its R1 model rivalled OpenAI's o1 on several performance benchmarks.

The predecessor of DeepSeek's V3 model, DeepSeek-V2, triggered an AI model price war in China after it was released last May.

The fact that DeepSeek-V2 was open-source and unprecedentedly cheap, only 1 yuan ($0.14) per 1 million tokens - or units of data processed by the AI model - led to Alibaba's cloud unit announcing price cuts of up to 97% on a range of models.

Other Chinese tech companies followed suit, including Baidu, which released China's first equivalent to ChatGPT in March 2023, and the country's most valuable internet company Tencent.

Liang Wenfeng, DeepSeek's enigmatic founder, said in a rare interview with Chinese media outlet Waves in July that the startup "did not care" about price wars and that achieving AGI (artificial general intelligence) was its main goal.

OpenAI defines AGI as autonomous systems that surpass humans in most economically valuable tasks.

While large Chinese tech companies like Alibaba have hundreds of thousands of employees, DeepSeek operates like a research lab, staffed mainly by young graduates and doctorate students from top Chinese universities.

Liang said in his July interview that he believed China's largest tech companies might not be well suited to the future of the AI industry, contrasting their high costs and top-down structures with DeepSeek's lean operation and loose management style, Reuters reported.

"Large foundational models require continued innovation, tech giants' capabilities have their limits," he said.

U.S. President Donald Trump told reporters on Monday that Microsoft (MSFT.O), is in talks to acquire TikTok and that he would like to see a bidding war over the app, Reuters reported.

Microsoft and TikTok did not immediately respond to Reuters' requests for a comment outside regular business hours.

Trump has previously said that he was in discussions with several parties about purchasing TikTok and expects to make a decision on the app's future within the next 30 days.

The app, which has about 170 million American users, was briefly taken offline just before a law requiring ByteDance to either sell it on national security grounds or face a ban took effect on Jan. 19, read the report.

Trump, after taking office on Jan. 20, signed an executive order seeking to delay by 75 days the enforcement of the law that was put in place after U.S. officials warned that there was a risk of Americans' data being misused under ByteDance.

TikTok began restoring its services on Sunday after President-elect Donald Trump said he would revive the app's access in the U.S. when he returns to power on Monday, Reuters reported.

"Frankly, we have no choice. We have to save it," Trump said at a rally on Sunday ahead of his inauguration, adding that the U.S. will seek a joint venture to restore the short-video sharing app used by 170 million Americans.

In a message to users hours before the rally, TikTok said: "As a result of president Trump's efforts, TikTok is back in the U.S."

TikTok also issued an earlier statement after U.S. users reported being able to access the Chinese-owned service's website while the far more widely used TikTok app itself began coming back online for some users with just a few basic services. As of Sunday evening, the app remained unavailable for download on U.S. app stores.

"In agreement with our service providers, TikTok is in the process of restoring service," TikTok said in the earlier statement that also thanked Trump for "providing the necessary clarity and assurance to our service providers that they will face no penalties (for) providing TikTok to over 170 million Americans and allowing over 7 million small businesses to thrive."

TikTok’s public thanks to Trump, the day before he takes office, comes at a tense moment in U.S.-China relations. Trump has said he intends to place tariffs on China but has also indicated he hopes to have more direct contact with China’s leader.

The Chinese Embassy in Washington on Friday accused the U.S. of using unfair state power to suppress TikTok. "China will take all necessary measures to resolutely safeguard its legitimate rights and interests," a spokesperson said.

TikTok stopped working for U.S. users late on Saturday before a law shutting it down on national security grounds took effect on Sunday. U.S. officials had warned that under Chinese parent company ByteDance, there was a risk of Americans' data being misused, read the report.

Trump said he would "extend the period of time before the law's prohibitions take effect, so that we can make a deal to protect our national security."

"I would like the United States to have a 50% ownership position in a joint venture," he wrote on Truth Social.

Trump said the executive order would specify there would be no liability for any company that helped keep TikTok from going dark before his order.

Trump had earlier said he would most likely give TikTok a 90-day reprieve from the ban after he takes office, a promise TikTok cited in a notice posted to users on the app.

"A law banning TikTok has been enacted in the U.S. Unfortunately, that means you can't use TikTok for now. We are fortunate that President Trump has indicated that he will work with us on a solution to reinstate TikTok once he takes office. Please stay tuned," a message notified users of TikTok, which disappeared from Apple (AAPL.O), and Google app stores late on Saturday.

Trump saving TikTok represents a reversal in stance from his first term in office. In 2020, he aimed to ban the app over concerns the company was sharing Americans' personal info with the Chinese government. More recently, Trump has said he has "a warm spot in my heart for TikTok," crediting the app with helping him win over young voters in the 2024 election.

In August 2020, Trump signed an executive order giving ByteDance 90 days to sell TikTok but then blessed a deal structured as a partnership rather than a divestment that would have included both Oracle (ORCL.N), and Walmart (WMT.N), taking stakes in the new company, Reuters reported.

Not everyone in Trump's Republican Party agreed with efforts to get around the law and "Save TikTok".

Republican senators Tom Cotton and Pete Ricketts said in a joint statement: "Now that the law has taken effect, there is no legal basis for any kind of 'extension' of its effective date. For TikTok to come back online in the future, ByteDance must agree to a sale that satisfies the law's qualified-divestiture requirements by severing all ties between TikTok and Communist China."

The U.S. has never banned a major social media platform. The law passed overwhelmingly by Congress gives the incoming Trump administration sweeping authority to ban or seek the sale of other Chinese-owned apps.

Other apps owned by ByteDance, including video editing app CapCut and lifestyle social app Lemon8, were also offline and unavailable in U.S. app stores as of late Saturday.

Apple and Google (GOOGL.O), did not immediately respond to requests for comment.

Web searches for "VPN" spiked in the minutes after U.S. users lost access to TikTok, according to Google Trends.

Users on Instagram fretted about whether they would still receive merchandise they had bought on TikTok Shop, the video platform's e-commerce arm.

Marketing firms reliant on TikTok have rushed to prepare contingency plans in what one executive described as a "hair on fire" moment after months of conventional wisdom saying that a solution would materialize to keep the app running.

TikTok CEO Shou Zi Chew plans to attend the U.S. presidential inauguration and attend a rally with Trump on Sunday, a source told Reuters.

Suitors including former Los Angeles Dodgers owner Frank McCourt have expressed interest in the fast-growing business that analysts estimate could be worth as much as $50 billion. Media reports say Beijing has also held talks about selling TikTok's U.S. operations to billionaire and Trump ally Elon Musk, though the company has denied that.

U.S. search engine startup Perplexity AI submitted a bid on Saturday to ByteDance for Perplexity to merge with TikTok U.S., a source familiar with the company's plans told Reuters. Perplexity would merge with TikTok U.S. and create a new entity by combining the merged company with other partners, the person added.

Privately held ByteDance is about 60% owned by institutional investors such as BlackRock and General Atlantic, while its founders and employees own 20% each. It has more than 7,000 employees in the U.S.
