Beijing is promoting the creation of a "global open source capital" by continuously optimizing the layout of computing resources, building high-quality data elements, and promoting the open source of artificial intelligence big models. Not long ago, the open source big model KimiK2 released by Beijing's Dark Side of the Moon Kimi topped the global open source model list. Recently, the Beijing-based artificial intelligence company "Dark Side of the Moon" released the open source big model KimiK2, which has demonstrated strong strength in autonomous programming, tool calling, mathematical reasoning, and other aspects. One week after the launch, the international authoritative big model ranking LMArena announced that this model took over DeepSeekR1 and became the world's number one open source model in the public vote of the open source big model community developers, and ranked fifth on the overall list of open and closed source big models. Open source technology allows global developers to break through geographical and institutional restrictions, attracting more technology companies and individual developers to participate in open source contributions.
