What is Kimi K2?

Kimi K2 is a state-of-the-art large language model (LLM) developed by Moonshot AI.
It is designed to excel in:

Deep reasoning

Tool use and agentic workflows
Long-context processing
Text generation
Coding and logical problem-solving

Kimi K2 stands out because of its Mixture-of-Experts (MoE) design, which allows the model to maintain ultra-high capacity while using only a portion of its parameters at a time, enabling powerful performance with greater efficiency.

Key Features of Kimi K2

1. Trillion-Parameter MoE Architecture

Kimi K2 uses a 1 trillion–parameter MoE architecture, but only ~32 billion parameters are active during inference.
This results in:

Higher reasoning capacity

Better factual accuracy
Faster performance compared to dense trillion-parameter models
Lower compute cost

2. Massive Context Window

Kimi K2 supports up to 128,000 tokens, enabling:

Entire books or long research documents in a single prompt

Long-form reasoning
Multi-step planning
Full conversational memory without losing track

A special variant, Kimi K2 Thinking, extends this to 256K tokens.
