# Moonshot AI Releases Kimi K3: 2.8 Trillion-Parameter Open Model

> Moonshot AI, one of China's fast-rising labs, has released Kimi K3, which it calls the largest open-weight model published to date at 2.8 trillion total parameters. Thanks to a mixture-of-experts design with 896 experts, only about 104 billion parameters activate for any given token, which keeps inference costs manageable while the full model holds far more knowledge. It handles text, images and video, and offers a context window of roughly a million tokens. The weights went out in late July with API access following, at pricing well below Western frontier rates. That combination, a very large capable model released openly and cheaply, is the real story. It continues a pattern of Chinese labs commoditizing the model layer and forcing everyone else to compete on price and application rather than raw capability. For developers and researchers outside the biggest companies, open weights of this scale are a gift and a complication at once, expanding what they can build while sharpening the debate over where the frontier and its risks now live.
