Moonshot AI, a Chinese startup, released Kimi K3, a 2.8 trillion-parameter open-source AI model—the world's largest. The model is positioned for long-context programming, information processing, and reasoning, though it trails proprietary competitors like Claude and GPT. If you're building on proprietary models, you now have a free 2.8 trillion-parameter alternative from a well-funded team. Moonshot has just handed your margin problem to you—the choice to self-host or resell is now openly available.
