Chinese artificial intelligence (AI) startup Moonshot AI on Thursday released its latest model, Kimi K3, which features 2.8 trillion parameters, making it the largest-parameter open-source AI model globally, the company said.
Kimi K3 natively supports visual understanding and boasts a context window of 1 million tokens. It has been optimized for complex tasks including software engineering, knowledge-intensive work, deep research and multimodal understanding, Moonshot AI noted.
Kimi K3's overall intelligence level is close to that of globally leading closed-source models as revealed by evaluations, according to the Beijing-based startup.
"We have open-sourced the complete model weights and distilled the core technologies into a toolchain, making it fully accessible to the public," said Fu Qiang, a technician with Moonshot AI.
With continued breakthroughs in core technologies, Chinese open-source large models have grown into a core supplier of the global AI ecosystem.
"Previously, cutting-edge models were mostly in the hands of a few closed-source platforms, so companies could only really 'buy' the capabilities they needed. But with the rise of mature open-source models, businesses can now build on their own data, workflows, and domain expertise to develop AI applications that are far better suited to their real-world use cases," said Zhong Xinlong, an associate researcher at the Future Industries Research Center of the China Center for Information Industry Development.
According to the World Intellectual Property Organization, China now accounts for over 60 percent of global AI patent applications, the highest share worldwide.

The ongoing China-ASEAN Expo serves as a bridge for China and the Association of Southeast Asian Nations (ASEAN) to boost trade flows, helping both sides reap shared development dividends.
Scheduled to run from Sept 17 to 21 in Nanning City of south China's Guangxi Zhuang Autonomous Region, the event draws more than 3,400 exhibitors from over 70 countries and regions.
This year, Timor-Leste is participating for the first time as a full ASEAN member and a co-host of the expo, with participants noting results have exceeded expectations, bolstered by China's vast market.
"I brought 60 packages of 250-gram coffee, which would be sold out in one day. Now I'm thinking that China market is open for everybody and it's very huge," said an exhibitor from Timor-Leste.
Participants also hailed the construction of China's Pinglu Canal, which officially opened to traffic on Wednesday.
The 134.2-km-long canal runs from Hengzhou, a county-level city in Guangxi, to the Beibu Gulf, the closest maritime outlet for much of southwest China.
The canal becomes a cost-competitive river-sea intermodal shortcut connecting ASEAN producers with the vast consumer market in southwest China, said the participants.
"In the past, shipments into the southwest China usually went by sea to Guangzhou and then overlands. Too many handover made it hard to keep products fresh. Losses were high and transit time was unreliable. Now that the canal is open, we can enter [the] Guangxi [Zhuang Autonomous Region] directly from the Beibu Gulf and move on to Yunnan, Guizhou and Sichuan restaurants, faster onto the supermarket shelves and tables in the southeast [part of China]," said an exhibitor from Vietnam.
With the formal signing of the China-ASEAN Free Trade Area (FTA) 3.0 Upgrade Protocol in Oct 2025, bilateral cooperation has expanded beyond economic and trade areas to emerging fields such as the digital economy and the green economy.
"I am looking for an investor to develop agriculture and integrated tourism with us in Malaysia," said an exhibitor from Malaysia.
Economic ties between China and ASEAN have continued to deepen. Bilateral trade topped 1 trillion U.S. dollars for the first time in 2025, totaling 1.05 trillion dollars, up 7.4 percent year on year. In the first seven months of 2026, trade between the two sides reached 744.41 billion dollars, an increase of 24.7 percent year on year and accounting for 21.8 percent of China's total foreign trade.
China has remained ASEAN's largest trading partner for 17 consecutive years, while ASEAN has been China's largest trading partner for six successive years.
