Kimi K3 Explained!

Kimi K3: The First Open-Weights Model Setting the Frontier (3T Params, MOE, Agentic Coding) I break down why Kimi K3 feels like a new “DeepSeek moment,” arguing it’s the first open-weights model that actually sets the frontier for specialized agentic coding. I cover its 3T-parameter scale, MOE architecture (896 experts, 16 routed per token), native multimodal vision, and 1M context window, plus how it ranks highly on the AI Index and excels in coding/web dev benchmarks like Terminal Bench 2.1 while lagging in general chat and some tests like Humanity’s Last Exam and hallucination rate. I explain why Kimi models are ecosystem-friendly bases for post-training (e.g., Cursor, Cognition/Windsor, Thinking Machines) and discuss frontier-level pricing, token efficiency, enterprise focus, and how this could pressure other labs to lower prices. I also preview upcoming comparisons vs Fable 5, GPT 5.6, Sol, and GLM 5.2.
