• qwen-max

• qwen-max-2025-01-25

Model Overview

A large-scale Mixture-of-Experts (MoE) language model developed by Alibaba Cloud. It excels in language understanding, generation, and task performance across a variety of modalities. Mixture-of-Experts (MoE) Architecture: Uses 64 specialized "expert" networks, activating only relevant ones per task for efficient processing. Extensive Multilingual Support: Supports 29 languages, including Chinese, English, and Arabic. Long-Context Optimization: Supports 32K context windows with 8K generation. High Stability: Demonstrates high stability in maintaining prompt instructions, with no erroneous replies during extensive testing.

How to Make a Call

1

Setup You Can’t Skip

▪️ Create an Account: Visit the AI/ML API website and create an account (if you don’t have one yet). ▪️ Generate an API Key: After logging in, navigate to your account dashboard and generate your API key. Ensure that key is enabled on UI.

2

Copy the code example

At the bottom of this page, you'll find a code example that shows how to structure the request. Choose the code snippet in your preferred programming language and copy it into your development environment.

3

Modify the code example

▪️ Replace <YOUR_AIMLAPI_KEY> with your actual AI/ML API key from your account. ▪️ Insert your question or request into the content field—this is what the model will respond to.

^_(Optional) Adjust other optional parameters if needed

Only model and messages are required parameters for this model (and we’ve already filled them in for you in the example), but you can include optional parameters if needed to adjust the model’s behavior. Below, you can find the corresponding API schema, which lists all available parameters along with notes on how to use them.

5

Run your modified code

Run your modified code in your development environment. Response time depends on various factors, but for simple prompts it rarely exceeds a few seconds.

If you need a more detailed walkthrough for setting up your development environment and making a request step by step — feel free to use our Quickstart guide.

API Schema

Generate a conversational response using a language model.

post

Creates a chat completion using a language model, allowing interactive conversation by predicting the next response based on the given chat history. This is useful for AI-driven dialogue systems and virtual assistants.
