Kimi K2 Instruct is Moonshot's post-trained variant of the base Kimi K2 model, tuned for instruction following, conversational use, and agentic problem solving. It uses the 1 trillion total parameter Mixture-of-Experts architecture with 32 billion active parameters and a 128K token context window. Trained with the Muon optimizer, the model targets tool use, reasoning, and autonomous task execution. Moonshot reports strong results across coding (53.7 on LiveCodeBench v6, 85.7 on MultiPL-E), mathematics (69.6 on AIME 2024), and reasoning (89.5 on MMLU), making it well suited to general-purpose assistance with reasoning demands. The model is built for tool calling in agentic applications and is optimized for immediate, reflex-style responses rather than long deliberation. It supports structured output and runs on inference engines including vLLM, SGLang, and KTransformers.

Kimi K2 Instruct runs on a single route through the Opper gateway today, so its availability is that provider's availability.
Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. Set up a fallback chain.
Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider Opper monitors.
Each route hosting Kimi K2 Instruct has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
Zero data retention is on by default on Pay-as-you-go — no action required. No training on customer data. US; SCCs; DPA available.
Call Kimi K2 Instruct through the Opper gateway with one API key. Let your coding agent set it up, or call it directly — Opper is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.
Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up Opper for you.
