A new milestone has been reached in the open source AI space. Open models from China are now outperforming recently released competitors, such as Opus 4.8, just two months after their debut. Kimi K3, now holding the top spot among open weights models at 57 in the Artificial Analysis Intelligence Index, has made its weights publicly available. The 2.6T parameter model, released under the 'Kimi K3 License,' is labeled as 'Commercial Use Restricted.' This licensing means businesses offering model-as-a-service solutions with over $20 million in annual revenue must seek additional agreements. Products exceeding 100 million monthly active users or generating $20 million in monthly revenue must clearly display "Kimi K3" in their user interface. A technical report outlining the model's architecture and training methods has also been released. šŸ“° @aipost
