## Overview

Kimi K2.6 is a general-purpose model from Moonshot AI built for stable long-horizon coding, reliable instruction following and self-correction. It accepts text, image and video input, supports thinking and non-thinking modes, and handles both dialogue and agent tasks. Its 256K-token context window suits large codebases.

Kimi K2.6 has a 256K-token context window. It accepts text, image and video input and returns text output. It was released on April 20, 2026.

## Capabilities

Kimi K2.6 supports reasoning and tool calling. It accepts text, image and video as input and produces text as output.

Moonshot AI documents multi-step tool invocation together with reasoning, so Kimi K2.6 can plan, call tools and revise its approach across a long task. It also supports automatic context caching, tool calls and JSON mode.

## Pricing

Kimi K2.6 costs $0.95 per 1M input tokens and $4.00 per 1M output tokens. Cache reads are $0.16 per 1M tokens.

Kimi K2.6 is available through RealRelay's OpenAI-compatible API.

## Use cases

Use Kimi K2.6 for long-horizon coding across languages such as Rust, Go and Python, covering frontend development, DevOps and performance optimization, with tool calls driving the edit-and-test loop.

Its image and video input also suit tasks such as reading UI screenshots, charts or screen recordings, and its thinking mode handles complex logic and mathematical problems.
