AIOpenRouter says Moonshot AI's Kimi K3.1 Pro is live on its platform, with a 1M-token context and multimodal support. Pricing is $2 per million input tokens and $10 per million output tokens, and the model is post-trained from Kimi K3 for long-horizon coding and agentic work.
AIWhy it matters.
The post gives context, pricing, and access routes for a new open-weight model available through OpenRouter, useful for comparing it with existing API options.
@OpenRouter
Introducing Kimi K3.1 Pro: our most capable 3T-class open-weight model. 🔹 1M-token context, 2.8T total / 104B active params (MoE), Multimodal. 🔹 Full-project coding: games in Unreal, Unity & Godot. 🔹 Excels at parametric 3D modeling in Blender & CAD. 🔹 More reliable at finance work: Accurate modeling with hallucination down by 65%. 🔹 Matching the strongest proprietary models across coding, agentic and knowledge benchmarks. Kimi K3.1 Pro and K3.1 Pro Highspeed (2–3× faster) are now live on http://Kimi.ai, Kimi Work, Kimi Code, and the Kimi API. Open weights by Nov 4, 2026. 🔗 API: http://platform.kimi.ai 🔗 Tech blog: http://kimi.ai/blog/kimi-k3-1-pro
