Free Qwen API: Use Alibaba's Qwen Models at No Cost

If you want to try Alibaba's Qwen models without a credit card, a billing account, or a wall of onboarding forms, this guide is for you. DreamPrompting runs a free Qwen API through an OpenAI compatible gateway, so you can send a request in the next minute and get a response back. The only setup is a free API key: sign in with Google at /account, no credit card, and it takes seconds. You point your existing tooling at one base URL and start building.

The gateway forwards your requests to many providers' free tiers with automatic failover. When one provider is busy or offline, the router tries another that serves the same class of model. That design is what makes a genuinely free Qwen API practical rather than fragile. You do not have to track which upstream is up, rotate keys, or maintain retry logic of your own, because the routing layer handles that for you and returns a normal response when a healthy backend answers.

What Qwen is good at

Qwen is Alibaba's family of large language models, and it has become a favorite for a few reasons:

If your project touches translation, cross language support, or coding assistance, Qwen is a sensible model to reach for. You can compare it against other options any time on the models page or in the live chat playground.

How the free Qwen API works

The base URL is https://dreamprompting.com/api/v1. It speaks the same protocol as the OpenAI Chat Completions endpoint, so anything that talks to OpenAI can talk to this gateway with only a base URL change. Every request carries your free API key, so pass it anywhere a key is expected and send it as Authorization: Bearer YOUR_API_KEY on raw HTTP calls.

One honest note about model selection. Qwen is served through providers whose availability shifts over time, so the exact Qwen model ids come and go. The reliable path is to set "model": "auto" and let the router pick a healthy backend with failover. If you want a specific id, list what is live first (shown below) and use that. This is fair-use free through providers' free tiers, so treat capacity as shared and be reasonable with volume.

Call the free Qwen API with curl

Here is a minimal request using auto so the gateway routes you to an available model:

curl https://dreamprompting.com/api/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "auto",
    "messages": [
      {"role": "user", "content": "Explain quicksort in three sentences."}
    ]
  }'

List live models before pinning a Qwen id

To see which ids are currently available, including any Qwen variants online right now, call the models endpoint:

curl https://dreamprompting.com/api/v1/models \
  -H "Authorization: Bearer YOUR_API_KEY"

Scan the returned list for a Qwen id (for example something under a qwen/ prefix) and drop it into the model field as "provider/model". If it disappears later, fall back to auto. You can also check /api/v1/quota to see current usage headroom.

Python example with the OpenAI SDK

Because the free Qwen API is OpenAI compatible, the official Python SDK works out of the box. Just swap the base URL and pass your free key:

from openai import OpenAI

client = OpenAI(
    base_url="https://dreamprompting.com/api/v1",
    api_key="YOUR_API_KEY",
)

resp = client.chat.completions.create(
    model="auto",
    messages=[
        {"role": "system", "content": "You are a helpful coding assistant."},
        {"role": "user", "content": "Write a Python function that reverses a linked list."},
    ],
)

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

Want tokens as they arrive? Add stream=True to the call (or "stream": true in raw JSON) and iterate over the chunks. The gateway allows up to 100 requests per minute, plus a rolling 24 hour account quota of 5,000 requests and 500,000 tokens, which is plenty for prototypes, scripts, and small apps. Full parameter details live in the API docs.

FAQ

Is the free Qwen API really free? Yes, it is free to use and there is no card involved. You do need a key, and it is free to create in seconds at /account. It runs on providers' free tiers under fair use, so please keep your volume reasonable so the service stays healthy for everyone.

Why should I use "auto" instead of a fixed Qwen id? Qwen availability shifts across providers. Setting auto lets the router pick a healthy backend and fail over automatically, so your requests keep working even when a specific id goes offline.

Do I need to change my code to switch from OpenAI? No. Point the base URL at https://dreamprompting.com/api/v1, set the key to your free DreamPrompting key, and your existing OpenAI client code runs unchanged.
