Alibaba released the next generation of its open-sourced large language models, Qwen3, on Tuesday — and experts are calling it yet another breakthrough in China’s booming open-source artificial intelligence space.

In a blog post, the Chinese tech giant said Qwen3 promises improvements in reasoning, instruction following, tool usage and multilingual tasks, rivaling other top-tier models such as DeepSeek’s R1 in several industry benchmarks. 

The LLM series includes eight variations that span a range of architectures and sizes, offering developers flexibility when using Qwen to build AI applications for edge devices like mobile phones.

Qwen3 is also Alibaba’s debut into so-called “hybrid reasoning models,” which it says combines traditional LLM capabilities with “advanced, dynamic reasoning.”

According to Alibaba, such models can seamlessly transition between a “thinking mode” for complex tasks such as coding and a “non-thinking mode” for faster, general-purpose responses. 

“Notably, the Qwen3-235B-A22B MoE model significantly lowers deployment costs compared to other state-of-the-art models, reinforcing Alibaba’s commitment to accessible, high-performance AI,” Alibaba said. 

The new models are already freely available for individual users on platforms like Hugging Face and GitHub, as well as Alibaba Cloud’s web interface. Qwen3 is also being used to power Alibaba’s AI assistant, Quark.

China’s AI advancement

AI analysts told CNBC that the Qwen3 represents a serious challenge to Alibaba’s counterparts in China, as well as industry leaders in the U.S.  

In a statement to CNBC, Wei Sun, principal analyst of artificial intelligence at Counterpoint Research, said the Qwen3 series is a “significant breakthrough—not just for its best-in-class performance” but also for several features that point to the “application potential of the models.” 

Those features include Qwen3’s hybrid thinking mode, its multilingual support covering 119 languages and dialects and its open-source availability, Sun added.

Open-source software generally refers to software in which the source code is made freely available on the web for possible modification and redistribution. At the start of this year, DeepSeek’s open-sourced R1 model rocked the AI world and quickly became a catalyst for China’s AI space and open-source model adoption.  

“Alibaba’s release of the Qwen 3 series further underscores the strong capabilities of Chinese labs to develop highly competitive, innovative, and open-source models, despite mounting pressure from tightened U.S. export controls,” said Ray Wang, a Washington-based analyst focusing on U.S.-China economic and technology competition.

According to Alibaba, Qwen has already become one of the world’s most widely adopted open-source AI model series, attracting over 300 million downloads worldwide and more than 100,000 derivative models on Hugging Face. 

Wang said that this adoption could continue with Qwen3, adding that its performance claims may make it the best open-source model globally — though still behind the world’s most cutting-edge models like OpenAI’s o3 and o4-mini.  

Chinese competitors like Baidu have also rushed to release new AI models after the emergence of DeepSeek, including making plans to shift toward a more open-source business model. 

Meanwhile, Reuters reported in February that DeepSeek is accelerating the launch of its successor to its R1, citing anonymous sources.

“In the broader context of the U.S.-China AI race, the gap between American and Chinese labs has narrowed—likely to a few months, and some might argue, even to just weeks,” Wang said. 

“With the latest release of Qwen 3 and the upcoming launch of DeepSeek’s R2, this gap is unlikely to widen—and may even continue to shrink.”

Blip, dip, pullback or the beginning of the end? Global investors weigh in on stock sell-off

Blip, dip, pullback or the beginning of the end? Global investors weigh in on stock sell-off

Global investor sentiment for artificial intelligence remains buoyant, despite on the ongoing stock sell-off.  

European and Asia markets have seen days of consecutive losses, tracking their U.S. counterparts lower as pressures mount on AI-related stocks and their valuations. The pan-European Stoxx 600 on Tuesday notched its lowest level in a month, with major bourses opening mixed on Wednesday, while Asia-Pacific markets fell.  

Stateside, stock futures were little changed overnight after major U.S. indexes extended their losses. AI-related stocks such as NvidiaPalantir, and Microsoft are among those feeling the pressure.

“We do think this is an AI specific pullback. We don’t think this is the beginning of the bear market,” Emma Wall, head of investment analysis at Hargreaves Lansdown, told CNBC’s “Squawk Box Europe.”  

When considering whether this is the “beginning of the end” or a moment marking “the big pullback,” Wall argued that while we are overdue a “major global market correction,” the current downturn is yet to bring this shift.

Many markets outside of the U.S. — particularly in Europe and the U.K. — already reflect much of the negative news, she said, adding that she sees the pressure as sector specific.

Nvidia earnings preview: Investors brace for AI reality check

It is, however, an opportunity to rebalance portfolios, as “even taking into consideration this week, most people have had a really good run, even in AI stocks,” Wall said.

Mike Wilson, chief U.S. equity strategist and chief investment officer at Morgan Stanley, echoed this sentiment. He said markets have been in a correction for the past six weeks but “it’s not the end of the AI cycle.” 

All eyes are on Nvidia, considered the bellwether of AI, as it’s due to post third-quarter earnings after the closing bell on Wednesday.  

“Whatever happens tonight is, if it is a blip, is a pullback, it’s probably a dip to be bought. But I think we are in the midst of somewhat of a correction right now,” Wilson told CNBC’s “Inside India,” adding that he thinks it’s the middle-inning.

“The credit part of this spending is just beginning, meaning we’re just starting to raise money in the credit markets. It’s not like that money is going to sit there and they’re not going to spend it, which means there’s probably time on the clock with these intermittent kind of pullbacks,” he added.

Companies and investors are engaged in a delicate dance.

On one side, AI labs and their partners are making big promises and aggressive plays, according to Jason Thomas, head of global research and investment strategy at Carlyle. “But it’s not incumbent upon investors to believe them,” he told CNBC’s Julianna Tatelbaum, from the firm’s annual conference.

“Investors, of course, have to ensure that they are getting compensated for the risk that things don’t work out quite as planned, and I think that there’s a sense that perhaps there’s been some assets in the space that have been priced to best case scenarios. So I think that that’s the reassessment that’s going on right now,” he said.

Hyperscalers’ rising capex

The sell-off comes as the pace of debt dealmaking picks up, fueling speculation that it may have unsettled investors, many of whom have remained bullish on AI as long as companies post sound earnings. Google-owner Alphabet and Meta have issued bonds, for example.  

“It’s not a problem, as long as the funding markets are there, meaning they’re raising the debt,” Wilson added. “I mean, there’s investors lined up,” he said.

It does however, become a problem when this is no longer the case, but “we haven’t seen that yet,” he said.

AI has fundamentally changed the strategy for many Big Tech firms, particularly when it comes to U.S. hyperscalers, which have morphed into capex-heavy companies from once asset-light businesses. Global investors are now assessing this new dynamic. Bank of America‘s latest Global Fund Managers Survey found that, for the first time in two decades, fund managers are concerned about hyperscalers “overinvesting.

“[Hyperscalers] traded at very high price-to-book ratios, which made a lot of sense. You don’t value a money-printing machine based on the cost of the paper or based on the cost of the printing press. And that’s essentially what they were, these massive money printing machines where most of their assets were intangible, proprietary technology, the digital platforms,” said Carlyle’s Thomas.

“Now they’ve actually started to invest so much that 70% of their cash flow is being consumed by capital spending and, if you look at their book value now, 70% actually consists of property, plant and equipment, largely data centers. That’s a four-fold increase from a decade ago,” he added.

The Dutch government on Wednesday said it suspended its intervention at Chinese-owned chipmaker Nexperia, following constructive talks with Chinese authorities.

“We see this as a show of goodwill,” Dutch Economy Minister Vincent Karremans said in a statement, posted on social media platform X.

In a separate letter to parliament, Karremans said it had become clear Beijing now appeared to be permitting companies from European and other countries to export Nexperia chips, adding that “this is an important step.”

The development appears to bring an end to a bitter dispute between the Netherlands and China, one that had prompted global automotive groups to raise the alarm over a worsening chip shortage.

The Dutch economic affairs ministry said the country considered it to be “the right moment to take a constructive step” by suspending the order under the so-called Goods Availability Act. It added that it would continue to hold talks with Chinese authorities over the coming weeks.

CNBC has reached out to Nexperia, which is based in the Netherlands but owned by the Chinese company Wingtech, and the Chinese embassy in the U.K. for comment.

The situation involving Nexperia began in September, when the Dutch government invoked a Cold War-era law to effectively take control of the company. The highly unusual move was reportedly made after the U.S. raised security concerns.

In making the decision, the Dutch government cited fears that technology from the company — which specializes in the high-volume production of chips used in automotive, consumer electronics and other industries — “would become unavailable in an emergency.”

China responded by blocking exports of the firm’s finished products.

European Union trade chief Maros Sefcovic on Wednesday welcomed the Dutch government’s decision to suspend its intervention at Nexperia, saying the move will help to stabilize strategic supply chains.

“Continued constructive engagement with partners remains essential to securing reliable global flows. I stay in close contact with all my counterparts,” Sefcovic said in a post on X.

Shares of Europe’s auto giants were trading mixed on Wednesday morning. Milan-listed Stellantis, the parent of Jeep, RAM, Dodge and Chrysler, was last seen up 0.1%.

Germany’s Volkswagen, Mercedes-Benz Group and BMW, meanwhile, were all trading slightly lower at 11:12 a.m. London time (6:12 a.m. ET).
