[Kimi K3 Officially Open-Sourced] According to monitoring by Beating, the dark side of the moon has officially open-sourced the Kimi K3 model weights and adopted a custom Kimi K3 License agreement, allowing for research, deployment, fine-tuning, and secondary development. Developers can now download the model from Hugging Face for self-deployment, fine-tuning, and testing. First-day integrations around K3 have already begun in advance. Modal, Together AI, Nebius, GMI Cloud, Baseten, and Fireworks AI have all announced that they will provide hosting or inference services on the day the weights are released. The two major open-source inference frameworks, vLLM and SGLang, have also offered first-day support. Developers can deploy directly upon obtaining the weights without waiting for framework adaptation. Subsequent optimizations will focus on long-context handling, high throughput, and the operational efficiency of KDA linear attention. [Original Link]
