Moonshot AI is a Chinese artificial intelligence company focused on building large language models, which are AI systems trained on massive amounts of text to understand and generate human language. The company is best known for its Kimi product line, which has become one of the more notable open and closed AI model offerings coming out of China.
The company has shown interest in the technical side of running large models at scale. It has shared details about its large-scale LLM serving architecture, which is the system behind the scenes that lets multiple people use a massive AI model at the same time without it crashing or slowing down. This kind of infrastructure work matters because it is one of the biggest practical challenges in AI today.
Moonshot AI's main product is the Kimi series of models. The most discussed version so far is Kimi K2, which uses a technique called mixture of experts, or MoE. In a standard AI model, every piece of input text passes through all of the model's parts. In a mixture-of-experts model, the system picks only the most relevant subset of its components for each task, which can make the model faster and more efficient without sacrificing quality. Kimi K2 was described as a state-of-the-art mixture-of-experts language model and drew significant attention when it was shared online.
Alongside K2, Moonshot AI has also released versions like Kimi K2-Instruct, which is tuned for following instructions, and Kimi-Linear, a lighter version of the model. The company has also been the subject of rumors around a next flagship model sometimes referred to as Kimi K4, though those claims have not been confirmed.
The Kimi models are available both as open-weight releases, where researchers can inspect and build on the model's inner workings, and as served APIs that developers can call directly.
Moonshot AI is best known for developing the Kimi family of large language models, including Kimi K2, which uses a mixture-of-experts architecture to balance quality and efficiency.
Moonshot AI has released some Kimi models as open-weight, meaning researchers can access the model's internal parameters. It also offers served API versions for developers who want to use Kimi without running the model themselves.
