Beijing, July 18 (EFE).- Chinese startup Moonshot AI has unveiled Kimi K3, which it describes as the world’s largest open-source artificial intelligence model, claiming it outperforms several leading systems from OpenAI and Anthropic in key benchmarks amid an intensifying tech rivalry between Beijing and Washington.
Moonshot AI said Kimi K3 features 2.8 trillion parameters, the measure commonly used to indicate an AI model’s complexity during training, surpassing other open-source Chinese models such as DeepSeek V4 Pro (1.6 trillion parameters) and Zhipu AI’s GLM-5 series (744 billion).
According to the company, Kimi K3 is designed for long-context programming, complex reasoning, and knowledge-intensive tasks. The model is already available through the Kimi chatbot, the Kimi Work application, Kimi Code, and its API, while the full release of its model weights is scheduled for July 27.
Competitive performance at a lower cost
Moonshot acknowledged that K3 «still trails the most powerful proprietary models,» namely Claude Fable 5 and GPT-5.6 Sol, but said it consistently outperformed the other models included in its comparisons.
