Kimi model for long-context chat, coding, and agentic reasoning
Kimi K2 Instruct by moonshotai is offered by 6 providers on this page. Its reference price is $1.00 per 1M input tokens and $3.00 per 1M output tokens. The lowest paid channel is NanoGPT at $0.40 / $1.80 per 1M, about 2.6× below the reference price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
The context window is 131,072 tokens at the reference host, but hosts report different limits, from 32,768 to 256,000, so the usable window depends on the provider you pick. It supports tool use and structured output. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2024-10.
