Sovereign inference — Kimi K3.1 Pro

Your sovereign, private Kimi K3.1 Pro

Kimi K3.1 Pro is Moonshot AI's proprietary successor to Kimi K3: a 2.8T-parameter model with a 1M-token context window, native image input and extended reasoning. It scores 46 on the Artificial Analysis Intelligence Index (up from 29 for the released K3 build) and leads on long-horizon agentic work. Note the trade-off: output speed is roughly 31 tokens per second on the standard endpoint, so prefer the High-speed variant for interactive use. A reasoning model in the ultra tier, served on ToothFairyAI's AU, EU and US endpoints — private by default, billed in US dollars per million tokens at the published rates below. No training on your data, no vendor lock-in.
