Alibaba's New AI Models: Quen 3 and Quen 3 Coder

This week, Alibaba released two significant AI models: an upgraded Quen 3 model and the Quen 3 Coder. The Quen 3 model has demonstrated state-of-the-art performance, surpassing models like Claude Sonnet in various benchmarks, including math, coding, science, and reasoning.

The Quen 3 Coder is an agentic code model with a mixture of experts architecture, boasting 480 billion parameters, with 35 billion active during inference. This design allows for high performance without excessive computational demands. The Quen 3 Coder achieves state-of-the-art scores in agentic coding, agentic browser use, and tool use, rivaling closed-source models like Claude Sonnet and even OpenAI's GPT-4.1 on benchmarks like Swaybench Verified and Spider Ader.

Example: The video showcases a demo where Quen 3 Coder generates a bouncing ball in a rotating hypercube simulation in one shot, including visualization and controls for rotation and ball speed.

Alibaba's Quen Code CLI Tool

Alongside the Quen 3 Coder, Alibaba introduced the Quen Code CLI, an open-source command-line AI workflow tool based on the Gemini CLI framework. This tool is designed to enhance developer workflows by providing features similar to Cloud Code and other CLI tools, but optimized for the Quen 3 Coder.

Key Features of Quen Code CLI:

• Enhanced Parser Support: Improves code understanding and editing.
• Extended Tool Capabilities: Provides a wider range of tools for developers.
• Workflow Automation: Automates repetitive tasks.
• Better Codebase Understanding: Allows for more intelligent code edits.

Step-by-Step Installation and Setup of Quen Code CLI

1. Prerequisites: Ensure Node.js (latest version) is installed.
2. Installation: Use npm to install the Quen Code CLI from the GitHub repository (link in description). Command: npm install -g @alicloud/quncode
3. Verification: Verify installation by running quncode -v in the terminal.
4. Startup: Run the quncode command in the terminal to start the tool.
5. Configuration: Configure the theme and API settings.
   • For users in mainland China, apply for an API key via the provided link.
   • For users outside mainland China, use Model Studio to configure the API.
   • Alternatively, use an Open Router API key (OpenAI compatible) or a Model Scope key.
6. API Configuration Example (Open Router):
   • API Key: [Your Open Router API Key]
   • Base URL: OpenAI base URL
   • Model: quncode-3-coder

Usage and Capabilities of Quen Code CLI

• Natural Language Interaction: Interact with the tool using natural language to ask questions, edit files, or run commands.
• Customization: Create a quncode.md file to customize interactions.
• Codebase Integration: Add Quen Code CLI to your codebase for refactoring, optimization, documentation, and testing.
• Prototyping: Use the tool for rapid prototyping.

Example: The video demonstrates creating a SAS landing page using Quen Code CLI, which generates a decent base structure with animations in seconds.

KDF Flows: An AI-Powered Design Tool

The video also briefly promotes KDF Flows, an AI-powered design tool that generates design variations from sketches or ideas. It allows users to explore layouts, colors, and styles quickly and create full sets, mockups, and UI assets. KDF Flows is currently free to try, and users can earn bonus AI credits by sharing their designs and tagging KD.

Conclusion

Alibaba's release of the Quen 3 model and Quen 3 Coder, along with the Quen Code CLI tool, represents a significant advancement in open-source AI for coding and development. The Quen 3 Coder demonstrates competitive performance in agentic coding and tool use, while the Quen Code CLI offers developers a powerful and customizable AI-assisted workflow. While the tool is new and may have initial issues, its potential for enhancing code understanding, automation, and prototyping makes it a valuable asset for developers, especially those seeking open-source solutions.
