Kimi K2.6 API — unlimited & flat-rate access

Kimi K2.6 (also written “Kimi 2.6”) is Moonshot’s previous flagship agentic and coding model, served in the Frontier Pool alongside its successor Kimi K2.7 — so teams standardized on K2.6 can keep using it unchanged. CheapestInference serves it through an OpenAI- and Anthropic-compatible API on unlimited, flat-rate time-block subscriptions — so your cost does not scale with tokens.

Why unlimited Kimi K2.6

Section titled “Why unlimited Kimi K2.6”

A Frontier Pool subscription lets you use Kimi K2.6 through a standard OpenAI-compatible endpoint with no token caps — a flat monthly fee instead of per-token billing. Kimi K2.7 is Moonshot’s newer flagship and both are served in the same pool, so you can migrate on your own schedule (or stay on K2.6 for reproducible pipelines). Because it is OpenAI-compatible, it works in Cline, Roo Code, Continue, and any client that accepts a custom base URL, making it a direct alternative to Claude Code and Cursor for unlimited AI coding.

Common questions

Section titled “Common questions”

Is Kimi K2.6 still available, or only Kimi K2.7? Both. The Frontier Pool serves Kimi K2.6 and Kimi K2.7 side by side — send model: "kimi-k2.6" or model: "kimi-k2.7" with the same key.

What is the cheapest way to use Kimi K2.6? An unlimited time-block subscription. From $52/month ($44.20/mo billed annually) you reserve an 8-hour daily window and use Kimi K2.6 with no token caps — for predictable, high-volume work this is cheaper than per-token providers because the price does not rise with token count.

Is Kimi K2.6 OpenAI-compatible? Yes. Use model id kimi-k2.6 against https://api.cheapestinference.com/v1 with the OpenAI SDK, or the /anthropic endpoint with the Anthropic SDK.
