Shanghai, July 17 /Xinhua/ — Chinese artificial intelligence (AI) startup Moonshot AI on Thursday unveiled its model Kimi K3, which has 2.8 trillion parameters, making it the AI model with the largest number of parameters with open source in the world, the company said.
The Kimi K3 model initially supports visual understanding and has a context window of 1 million tokens. As noted by the company Moonshot AI, the model is optimized for solving complex tasks, including software development, deep research, and multimodal understanding.
“A larger number of parameters means a higher ceiling for the capabilities of this model and can provide more intelligent performance,” the company explained.
According to Moonshot AI data, the overall intelligence level of Kimi K3 is close to that of leading closed-source world models, as evidenced by the evaluation results.
Experts note that an increasing number of major Chinese open-source models are shifting from individual breakthroughs to collective achievements, offering new approaches to the global development of artificial intelligence.
