Timeline (last 90 days)
Kimi is Moonshot AI's large language model, callable through its OpenAI-compatible chat-completions endpoint.
CloutBot is an on-chain AI opponent powered by Moonshot AI's Kimi model for the CloutCall prediction game, always online and offering predictions whose reasoning process can be viewed.
Moonshot AI may release a new model in mid-October, having previously teased Kimi K3.1.
Kimi K2 is an open-source Mixture-of-Experts model released by Moonshot AI in 2025, with approximately 32 billion activated parameters and more than 1 trillion total parameters
SWE-2 is a coding model built by Cognition on top of Moonshot AI's Kimi K2 model, released on September 10, with a primary focus on cost efficiency
Moonshot AI has launched Kimi Code Desktop, a single-window Agent workspace programming tool.
Kimi Code Desktop is powered by Moonshot AI's K3 model.
Kimi Linear, introduced by Moonshot AI, is a hybrid linear attention architecture whose core is Kimi Delta Attention (KDA); most layers use KDA, with a full attention block reusing DeepSeek-V3 MLA retained every four layers.
OpenAI disclosed and addressed a coordinated operation to steal from the model, attributing the core activity cluster to individuals associated with Moonshot AI.
The video's author states that Moonshot AI has only approximately 300 employees and is regarded as surpassing Google.
