# Kimi K3 and Kimi K3 Fast with ZDR and US-based providers now on AI Gateway

By Steven Van · 2026-07-27

Both Kimi K3 models run on US providers with zero data retention, with fast mode about 50% dearer and US-only inference about 10% dearer.

Kimi K3 and Kimi K3 Fast can now be served from US-based providers on [Vercel](<https://creatorstoolbox.com/tools/vercel>) AI Gateway, including Baseten and Fireworks. Zero Data Retention (ZDR) is also supported for both models, as [Vercel announced](<https://vercel.com/ai-gateway/models/kimi-k3>) on 27 July 2026. Teams with data residency or compliance requirements can use the model on US infrastructure.

## Routing and failover

AI Gateway serves Kimi K3 from multiple providers and routes across them automatically for failover, higher uptime and more available throughput than any single provider offers. The model ID stays **moonshotai/kimi-k3**, and the gateway handles provider selection and fallback.

## Kimi K3 Fast

Kimi K3 Fast is a faster serving path that trades a higher per-token cost for lower latency. It costs about **50% more** than the base model. There are two ways to request it:

- Set the speed option to fast under providerOptions.gateway on the base model. The model stays moonshotai/kimi-k3, and requests fall back to standard speed when the fast tier is unavailable.

- Use the model ID moonshotai/kimi-k3-fast directly.

## US inference

To keep Kimi K3 requests on US data centers only, set inferenceRegion to { scope: 'zone', geoRegion: 'us' } under providerOptions.gateway. Regional pricing is about **10% more** than the regular variant.

## Zero Data Retention

ZDR can be turned on for every request in the AI Gateway dashboard settings, or per request by setting zeroDataRetention: true under providerOptions.gateway.
