The model which topped the chart is **Kimi K3** and it built by **Moonshot AI** and it is developed in **Beijing **outside and far from west. It is one of the largest open-weight AI system that ever released, and it also put a Chinese startup ahead of Anthropic on a solid benchmark that matters to real technical developers, not only just researchers. **Access without medium partner:** [China beaten Americas best Coding AI](https://www.mayhemcode.com/2026/07/kimi-k3-explained-specs-benchmarks-and.html) ## The Numbers That Started the Panic Kimi K3 is consists of **2.8 trillion parameter** mixture-of-experts model.
