Getting started

Get an API Key and export the API key as an environment variable. If you use the OpenAI SDK or DashScope SDK to make calls, install the SDK.

OpenAI compatible

Python

HELPCODEESCAPE-python
from openai import OpenAI
import os

client = OpenAI(
    api_key=os.getenv("DASHSCOPE_API_KEY"), # Do not hard-code credentials in your code. Always use environment variables or a key management service.
    base_url="https://dashscope.aliyuncs.com/compatible-mode/v1",
)
completion = client.chat.completions.create(
    model="qwen-math-plus",
    messages=[{'role': 'user', 'content': 'Derive a universal solution for the quadratic equation $ Ax^2+Bx+C=0 $'}])
print(completion.choices[0].message.content)

You can also go to the Model Studio console to try out the model.

Recommendations

1. Use English and LaTeX: Qwen-Math is designed for mathematical problems in English. For best results, use LaTeX for mathematical symbols and formulas in your input.

2. Standardize output : Use partial mode for precise control. It ensures that the output closely follows the provided prefix, which improves the accuracy and control of the results.

3. The model is set to temperature=0 by default. No adjustment is required.

4. Retrieve results easily : Qwen-Math places the final result in a \boxed{} block by default.

FAQ

How can I use Qwen-Math to solve mathematical problems in images?
Qwen-Math does not support image input. - If an image contains simple mathematical problems, you can use Qwen-VL or QVQ. - If an image contains complex mathematical problems, you can first use Qwen-VL or QVQ to extract the text from the image. Then, use Qwen-Math to solve the problem. For more information about the input and response parameters of Qwen-Math, see Qwen API reference.
Where can I find detailed information about error codes?
If the model call fails and returns an error message, see Error messages for resolution.
