About Kimi K2.6

Kimi K2.6 is Moonshot AI's open-source native multimodal agentic model with 1T total parameters and 32B activated per token. Built on a hybrid MoE architecture with 61 layers, 384 routed experts + 1 shared, 8 selected per token, MLA attention, and a dedicated MoonViT vision encoder (400M params). Delivers state-of-the-art performance in long-horizon coding (SWE-Bench Pro 58.6%, SWE-Bench Verified 80.2%), agentic workflows (BrowseComp 83.2%, AIME 2026 96.4%, GPQA-Diamond 90.5%), and visual reasoning (MMMU-Pro 79.4%). Supports 256K native context, thinking/instant modes, and thinking preservation across turns. Scalable to 300 sub-agents executing 4,000 coordinated steps. Released April 21, 2026 under Modified MIT License.
