Qwen Chat

Qwen models are served through the OpenAI-compatible Chat Completions API. Client applications only need to call Cubicspaces /v1/chat/completions.

Endpoint

POST /v1/chat/completions

Supported Models

Model	Notes
qwen3.6-flash	Lightweight fast model
qwen3.6-plus	Plus standard model

Actual model availability depends on account permissions and platform configuration.

Request Example

curl https://cubicspaces.cloud/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen3.6-flash",
    "messages": [
      { "role": "system", "content": "You are a concise assistant." },
      { "role": "user", "content": "Confirm that the Qwen API is working." }
    ],
    "temperature": 0.2,
    "stream": false
  }'

Streaming

curl https://cubicspaces.cloud/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "qwen3.6-plus",
    "messages": [
      { "role": "user", "content": "Introduce Qwen in one sentence." }
    ],
    "stream": true,
    "stream_options": {
      "include_usage": true
    }
  }'

Streaming responses follow the OpenAI SSE format. Read choices[0].delta.content from each data: chunk; the final chunk may include usage.

SDK Examples

Python

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://cubicspaces.cloud/v1"
)

response = client.chat.completions.create(
    model="qwen3.6-flash",
    messages=[
        {"role": "user", "content": "Confirm that the API is working."}
    ],
    temperature=0.2
)

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

Node.js

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: "YOUR_API_KEY",
  baseURL: "https://cubicspaces.cloud/v1"
});

const response = await client.chat.completions.create({
  model: "qwen3.6-plus",
  messages: [{ role: "user", content: "Confirm that the API is working." }],
  temperature: 0.2
});

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

Troubleshooting

HTTP 404 or model unavailable

Make sure the request path is /v1/chat/completions and model is set to an available model for your account, such as qwen3.6-flash or qwen3.6-plus. If the request still fails, contact your platform administrator to confirm model availability.
