China’s Moonshot AI releases world’s largest open source AI model Kimi K3

Moscow, July 17 (RIA Novosti/GNA) – Chinese artificial intelligence startup Moonshot AI has released the Kimi K3 model, which contains 2.8 trillion parameters, making it the world’s largest open-source AI model.

“Today, we are introducing Kimi K3 — our most capable model. Kimi K3 is a 2.8T-parameter model,” the company said in a statement. “It is the world’s first open 3T-class model.”

The model is designed to deliver advanced AI capabilities in long-term programming, intelligent information processing, and reasoning, it added.

While the Kimi K3 falls short in overall performance compared to the most powerful proprietary models, Claude Fable 5 and GPT 5.6 Sol, it delivered cutting-edge results and outperformed other systems tested, the company said.
