Moonshot AI's Kimi K3 is now available on Vercel AI Gateway. It is open-source, carries a 1-million-token context window, and accepts text, image, and video inputs natively. Thinking mode is always on.
K3 targets long-horizon software engineering and deep reasoning, with particular strength where code intersects visual and spatial tasks: frontend development, game development, and CAD workflows. To call it, set the model parameter to moonshotai/kimi-k3 in the AI SDK.
The fuller story is worth reading for the infrastructure details. AI Gateway passes through provider pricing with zero markup and no platform fee, including on Bring Your Own Key requests. It also layers in routing rules, per-key budgets, Zero Data Retention support, and failover handling. The combination of a capable open model and a cost-transparent routing layer is the real argument here.
