Source Summary
AI Gateway now serves **Kimi K3 and Kimi K3 Fast** through US-based providers including Baseten and Fireworks. Both support **Zero Data Retention**, while the gateway can route across providers for fallback and capacity.
Practical Implication
For coding agents, use moonshotai/kimi-k3 and select the speed option when latency matters; it falls back to standard speed if the fast tier is unavailable. Pin inferenceRegion for US-only processing, and inspect the endpoints API before choosing a provider or variant.
