Kimi K3 from Moonshot AI is now available on AI Gateway.

K3 is an open-source model with a 1M-token context window and native visual understanding, accepting text, image, and video inputs.

Built for long-horizon software engineering, knowledge work, and deep reasoning, K3 is especially strong where code meets visual and spatial reasoning, which suits frontend, game development, and CAD workflows. Thinking mode is always on.

To use Kimi K3, set model to moonshotai/kimi-k3 in the AI SDK :

import { streamText } from 'ai' ;

const result = streamText ( {

model : 'moonshotai/kimi-k3' ,

prompt : 'Trace this rendering bug across the codebase and open a PR with a fix.' ,

} ) ;

AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime.…
