Chinese AI startup Moonshot AI releases world's largest open‑source AI model, Kimi K3, with 2.8 trillion parameters
When technology ceases to be the monopoly of a few and becomes a shared asset, innovation accelerates and the boundaries of possibility expand. Open source is not just a licence but a philosophy that transforms AI from a closed club into a global workshop where anyone can take the tools and build their own future. Moonshot AI has made a move that changes the game: their new model, one of the most powerful in the world, is now available to everyone.
On Thursday, Chinese AI startup Moonshot AI released its latest model, Kimi K3, which contains 2.8 trillion parameters, making it the world's largest open‑source AI model, the company said. Kimi K3 natively supports visual perception and has a context window of 1 million tokens. It is optimised for complex tasks, including software development, knowledge‑intensive work, deep research and multimodal understanding, Moonshot AI noted. According to the Beijing‑based startup, Kimi K3's overall intelligence level is close to that of leading global closed‑source models. "We have open‑sourced all model weights and deconstructed core technologies into a toolchain, making it fully accessible to the public," said Fu Qiang, a technical specialist at Moonshot AI.
Thanks to continuous breakthroughs in core technologies, Chinese open‑source models have become a key provider for the global AI ecosystem. "Previously, advanced models were mainly in the hands of a few closed‑source platforms, so companies could only 'buy' the capabilities they needed. But with the emergence of mature open‑source models, enterprises can now use their own data, workflows and expertise to develop AI applications that are much better suited to their real‑world tasks," said Zhong Xinlong, a research fellow at the Centre for Advanced Industry Studies at the China Information Industry Development Centre.
The release of Kimi K3 marks an important milestone in the development of open‑source AI models. China is actively expanding its presence in this field, and according to the World Intellectual Property Organisation, China now accounts for more than 60 per cent of global AI patent applications, the highest in the world. Open source allows researchers and developers worldwide to adapt the model to their needs, accelerating progress in medicine, education, engineering and other fields. As CCTV+ reports. Kimi K3 is expected to become an important tool for thousands of companies and research centres seeking to deploy AI without huge costs of developing from scratch.
