Moonshot Releases Full Weights of Kimi K3: The First 3T-level Open Source Model
On July 27, 2026, Moonshot AI released the full weights of Kimi K3 on Hugging Face and GitHub: it has a total of 2.8T parameters, 104B activations, and a 1M context window, adopting MoE + KDA attention and MXFP4 native quantization. This article sorts out the architecture specifications, coding evaluation performance and vLLM self-hosting key points, and discusses the gap between open-source weights and closed-source cutting-edge models as well as the deployment threshold.

On July 27, 2026, Moonshot AI released the full weights of Kimi K3 on Hugging Face: with a total parameter size of 2.8T and 104B activation per token, the MXFP4 format weighs approximately 1.56 TB (split into 96 safetensors shards). The official claims it is the world's first open 3T-level model. This article sorts out its Stable LatentMoE architecture (896 choose 16 experts), KDA attention mechanism, 1-million-token context window, MoonViT-V2 multimodal capabilities, as well as self-hosting thresholds and API access methods, for developers to evaluate deployment and integration solutions.

On July 27, 2026, Moonshot AI released the full weights of Kimi K3 on Hugging Face and GitHub: a 2.8T total parameter MoE model with 16 activated experts out of 896, 104B activated parameters, 1 million token context window, and native multimodal capabilities. Based on the official README and arXiv technical report, this paper sorts out the key points of the KDA and Stable LatentMoE architectures, interprets the differences between Agent evaluations such as Terminal-Bench and model harness tests, and introduces the API, deployment paths via vLLM/SGLang, and the usage boundaries of the Kimi K3 License.

On July 27, 2026, Mooncake AI officially released the full model weights of Kimi K3. As the world's first 2.8T-parameter open-source MoE model, it supports 1 million-token context window and native multimodality. The single post on Hacker News gained over 600 upvotes, sparking heated discussions in the community regarding its performance comparison with Claude Fable 5 and the distillation controversy. This article sorts out the architecture specifications, benchmark positioning, the background of Alibaba's 36% shareholding, as well as developer guides for API and local deployment of Kimi K3.
