Moonshot AI Releases Kimi K3, Largest Open-Weight Model in History

Moonshot AI released Kimi K3 open-weight model on July 27, 2026. The model contains 2.8 trillion parameters with a total weight size of approximately 1.4 terabytes using MXFP4 four-bit quantization.

On July 27, 2026, at 00:00 UTC, Moonshot AI released the open weights for Kimi K3, its largest model to date. The model contains 2.8 trillion parameters, making it the largest open-weight model in history. Using MXFP4 four-bit quantization technology, the total weight size is approximately 1.4 terabytes. Kimi K3 features a 1-million-token context window and is designed for coding, reasoning, and agent workflows. The model also includes multimodal input capabilities, allowing it to process text, code, and images. Moonshot AI released the complete model weights under a modified MIT license. This open-source release is expected to accelerate AI research and application development worldwide. Industry experts view this as a milestone, signifying that Chinese open-source AI models have entered the frontier stage.
