Using Moonshot with Yunxin

Address Moonshot (Kimi) models with the moonshot/<model> prefix in the model field. You use the same Yunxin base URL (https://api.yuhuanstudio.com/v1) and your sk- API key — there is no separate Moonshot configuration on your side.

Capabilities vary by model. Query GET /v1/models to discover available models and what each one supports.

Usage example

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["YUNXIN_API_KEY"],
    base_url="https://api.yuhuanstudio.com/v1"
)

response = client.chat.completions.create(
    model="moonshot/model-id",
    messages=[{"role": "user", "content": "你好！"}]
)

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

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.YUNXIN_API_KEY,
  baseURL: "https://api.yuhuanstudio.com/v1",
});

const response = await client.chat.completions.create({
  model: "moonshot/model-id",
  messages: [{ role: "user", content: "你好！" }],
});

console.log(response.choices[0].message.content);

curl https://api.yuhuanstudio.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $YUNXIN_API_KEY" \
  -d '{
    "model": "moonshot/model-id",
    "messages": [{"role": "user", "content": "你好！"}]
  }'
