Moonshot AI Launches Kimi K3.1 Pro, Advancing Open-Weight AI for Game Development and 3D Design

Moonshot AI has released Kimi K3.1 Pro, its most capable open-weight model to date, now available on Design Arena and across its product ecosystem. The 2.8-trillion-parameter mixture-of-experts model targets complex coding workflows, 3D design, game development, and financial analysis—domains where previous models have struggled to combine speed, context, and real-time tool integration.
