Moonshot AI Releases Kimi K3, the World's Largest Open-Source Model by Parameters, Reaching 2.8 Trillion

TechFlow news, July 17, according to Xinhua News Agency, Beijing Moonshot AI Co., Ltd. officially released the new generation large model Kimi K3 on July 16, with a parameter count reaching 2.8 trillion, becoming the open-source model with the largest parameter count globally to date. Kimi K3 natively supports visual understanding, features a 1 million token context window, and is optimized for complex task scenarios such as software engineering, knowledge work, deep research, and multimodal understanding, with a comprehensive intelligence level approaching global frontier closed-source models. The model is trained using a self-developed underlying architecture. Moonshot AI stated that nearly 3 trillion parameters mean the model can store more knowledge and patterns, achieving "knowing more, thinking deeper, answering more accurately".
