Chinese startup Moonshot AI on Thursday released Kimi K3, a new open-weight large language model featuring 2.8 trillion parameters, making it the world's largest model of its kind by parameter count, the company said.
Kimi K3 natively supports visual understanding and offers a context window of one million tokens. It has been designed for demanding applications including software engineering, knowledge-intensive work, deep research and multimodal understanding.
The company said the larger parameter count provides a higher capability ceiling for tackling complex tasks, while its internal evaluations indicate an overall performance approaching that of leading proprietary AI models.
