Required Variables​

Environment Variables
os.environ["MOONSHOT_API_KEY"] = ""  # your Moonshot AI API key

ATTENTION:

Moonshot AI offers two distinct API endpoints: a global one and a China-specific one.

  • Global API Base URL: https://api.moonshot.ai/v1 (This is the one currently implemented)
  • China API Base URL: https://api.moonshot.cn/v1

You can overwrite the base url with:

os.environ["MOONSHOT_API_BASE"] = "https://api.moonshot.cn/v1"

Usage - LiteLLM Python SDK​

Non-streaming​

Moonshot Non-streaming Completion
import os
import litellm
from litellm import completion

os.environ["MOONSHOT_API_KEY"] = ""  # your Moonshot AI API key

messages = [{"content": "Hello, how are you?", "role": "user"}]

# Moonshot call
response = completion(
    model="moonshot/moonshot-v1-8k", 
    messages=messages
)

print(response)

Streaming​

Moonshot Streaming Completion
import os
import litellm
from litellm import completion

os.environ["MOONSHOT_API_KEY"] = ""  # your Moonshot AI API key

messages = [{"content": "Hello, how are you?", "role": "user"}]

# Moonshot call with streaming
response = completion(
    model="moonshot/moonshot-v1-8k", 
    messages=messages,
    stream=True
)

for chunk in response:
    print(chunk)

Usage - LiteLLM Proxy​

Add the following to your LiteLLM Proxy configuration file:

config.yaml
model_list:
  - model_name: moonshot-v1-8k
    litellm_params:
      model: moonshot/moonshot-v1-8k
      api_key: os.environ/MOONSHOT_API_KEY

  - model_name: moonshot-v1-32k
    litellm_params:
      model: moonshot/moonshot-v1-32k
      api_key: os.environ/MOONSHOT_API_KEY

  - model_name: moonshot-v1-128k
    litellm_params:
      model: moonshot/moonshot-v1-128k
      api_key: os.environ/MOONSHOT_API_KEY

Start your LiteLLM Proxy server:

Start LiteLLM Proxy
litellm --config config.yaml

# RUNNING on http://0.0.0.0:4000
Moonshot via Proxy - Non-streaming
from openai import OpenAI

# Initialize client with your proxy URL
client = OpenAI(
    base_url="http://localhost:4000",  # Your proxy URL
    api_key="your-proxy-api-key"       # Your proxy API key
)

# Non-streaming response
response = client.chat.completions.create(
    model="moonshot-v1-8k",
    messages=[{"role": "user", "content": "hello from litellm"}]
)

print(response.choices[0].message.content)
Moonshot via Proxy - Streaming
from openai import OpenAI

# Initialize client with your proxy URL
client = OpenAI(
    base_url="http://localhost:4000",  # Your proxy URL
    api_key="your-proxy-api-key"       # Your proxy API key
)

# Streaming response
response = client.chat.completions.create(
    model="moonshot-v1-8k",
    messages=[{"role": "user", "content": "hello from litellm"}],
    stream=True
)

for chunk in response:
    if chunk.choices[0].delta.content is not None:
        print(chunk.choices[0].delta.content, end="")

For more detailed information on using the LiteLLM Proxy, see the LiteLLM Proxy documentation.

Image / Vision Support​

Moonshot vision models (kimi-k2.5, kimi-latest, moonshot-v1-*-vision-preview, etc.) accept the standard OpenAI content array with image_url blocks.

LiteLLM automatically detects when your messages contain images and preserves the content array so the image payload reaches the Moonshot API. For text-only requests the content is flattened to a plain string, as required by Moonshot text models.

Moonshot Vision Example
import os
import litellm

os.environ["MOONSHOT_API_KEY"] = ""

response = litellm.completion(
    model="moonshot/kimi-k2.5",
    messages=[
        {
            "role": "user",
            "content": [
                {"type": "text", "text": "What is in this image?"},
                {
                    "type": "image_url",
                    "image_url": {"url": "https://example.com/image.png"},
                },
            ],
        }
    ],
)

print(response.choices[0].message.content)

Moonshot AI Limitations & LiteLLM Handling​

LiteLLM automatically handles the following Moonshot AI limitations to provide seamless OpenAI compatibility:

Temperature Range Limitation​

Limitation: Moonshot AI only supports temperature range [0, 1] (vs OpenAI's [0, 2])
LiteLLM Handling: Automatically clamps any temperature > 1 to 1

Temperature + Multiple Outputs Limitation​

Limitation: If temperature < 0.3 and n > 1, Moonshot AI raises an exception
LiteLLM Handling: Automatically sets temperature to 0.3 when this condition is detected

Tool Choice "Required" Not Supported​

Limitation: Moonshot AI doesn't support tool_choice="required"
LiteLLM Handling: Converts this by:

  • Adding message: "Please select a tool to handle the current issue."
  • Removing the tool_choice parameter from the request
