kimi-k3 ai-gateway compliance multi-provider zero-data-retention

Kimi K3 reaches US infrastructure with ZDR support

Moonshot AI's Kimi K3 now routes through US-based providers (Baseten, Fireworks) on Vercel's AI Gateway with automatic failover and optional zero-data-retention compliance mode.

Summary

Teams with data residency constraints can now run Kimi K3 without leaving US infrastructure, while automatic multi-provider routing eliminates single-provider latency and availability bottlenecks. The fast variant (~50% cost premium for lower latency) trades expense for response speed in latency-sensitive workflows.

Why it matters

Implementation verdict

Replaces single-provider Kimi K3 routing with managed multi-provider failover and regional isolation. Requires updating `model` ID to `moonshotai/kimi-k3` and optionally setting `inferenceRegion` or `zeroDataRetention` in providerOptions. Ready now—basic setup is one-line config change via AI SDK. Worth trying if compliance or uptime are constraints; cost-benefit of fast variant depends on latency requirements.

1.Kimi K3 and Kimi K3 Fast with ZDR and US-based providers now on AI Gateway
2.Running Kimi K3 on US-based providers lets teams with data residency and compliance requirements use the model on US infrastructure
3.Because AI Gateway serves the models from multiple providers, it automatically routes across them for failover, higher uptime, and more available throughput than any single provider offers
4.Kimi K3 Fast trades a higher per-token cost for lower latency
5.The fast variant costs ~50% more than the base model
6.Regional pricing is ~10% more than the regular variant
