Meet Kimi K2: The Trillion-Parameter Powerhouse on Neosantara AI

Er Rickow· October 2, 2025

Kimi K2, a groundbreaking Mixture-of-Experts (MoE) model from Moonshot AI. With a staggering one trillion total parameters, Kimi K2 is engineered for developers who need to tackle highly complex tasks with precision and scale.

What Makes Kimi K2 Special?

Kimi K2 isn't just another large language model; it's an intelligent agent. Its MoE architecture allows it to activate a massive 32 billion parameters for any given task, making it incredibly efficient. It's specifically optimized for "agentic" capabilities, which means it excels at:

• Advanced Tool Use: Integrating with external tools and APIs.
• Complex Reasoning: Breaking down difficult problems and thinking through solutions.
• Code Synthesis: Writing and understanding complex code with high accuracy.

It also boasts an impressive 128,000-token context window, allowing you to process and analyze vast amounts of information in a single request.

A Note on System Messages

Based on our testing, Kimi K2 performs best with direct user instructions rather than separate system messages. To get the best results, place all context and instructions directly within the user role message.

Here's how you can make a simple request using our OpenAI-compatible API:

# First, install the OpenAI library: pip install openai
import openai

# Configure the client to point to Neosantara AI
client = openai.OpenAI(
    base_url="https://api.neosantara.xyz/v1",
    api_key="YOUR_NEOSANTARA_API_KEY"
)

def ask_kimi(prompt):
    response = client.chat.completions.create(
        model="kimi-k2",
        messages=[
            {
                "role": "user",
                "content": f"You are a helpful assistant. Please answer the following question: {prompt}"
            }
        ]
    )
    print(response.choices[0].message.content)
