Introduction
Alibaba has released Quen 3 Coder 480B A35B Instruct, a powerful open agentic code model. It's a mixture of experts model with 480 billion parameters (35 billion active) and supports a 256k context window, scalable to a million tokens.
Performance and Benchmarks
- Quen 3 Coder achieves top-tier results in multi-agentic coding benchmarks.
- It outperforms open models like Kim K2 and even competes with closed-source models like DeepSeek V3 and Claude Sonnet 4 on benchmarks like Terminal Bench, Swaybench, ADER, and Spider.
- The model excels in agent capabilities.
- Example: A physics-based chimney demolition simulation was fully generated from a single prompt.
- Example: Coin 3 coder within Klein created an animation, multicolor, and interactive dashboard using p5.js in one shot.
Quen Code: Command Line Tool
- Alibaba open-sourced Quen Code, a command-line tool for agentic coding.
- It's forked from the Gemini code CLI tool.
- It includes custom prompts and a function calling protocol to unlock Quen 3 Coder's potential.
- It integrates with developer tools like MCPS.
Accessibility and Usage
- The model is accessible for free through a chatbot.
- Users can access it via API through Alibaba Cloud Model Studio.
- Local installation is possible, including a smaller quantized version.
- Quen Code is available on GitHub (open source).
- Free API access will be available through OpenRouter.
Zapier Sponsorship
- Zapier agents are AI-powered teammates that automate tasks across 7,000+ apps.
- Example: The outreach agent finds leads, enriches data, and sends personalized emails.
- Zapier offers pre-built agent templates for sales call analysis, content creation, and support ticket handling.
Testing and Demonstrations
The video demonstrates Quen 3 Coder's capabilities through several tests:
- Animated Weather Card:
- Prompt: Generate an animated weather card for San Francisco.
- Result: The model successfully generated a weather card with accurate animations for different weather conditions.
- The generated card can be deployed and shared via a link.
- SaaS Landing Page:
- Prompt: Create a SaaS landing page with multiple features.
- Result: The model generated a proficient front-end design, comparable to high-quality outputs.
- The quality surpasses previous open-source models like Quen 2.5.
- Animated Neural Network:
- Prompt: Generate an animated neural network visualization with pulsing nodes and connections.
- Result: The model created a simulation with interactive elements (reset, start/stop, speed control).
- It integrated HTML, CSS, JavaScript, and p5.js effectively.
- CSV Data Visualizer:
- Prompt: Build a single-page web application to parse CSV data from user input/file upload and generate multiple charts (bar, line, etc.).
- Result: The model created a CSV data visualizer with a dashboard, including bar and comparison charts.
- It used sample data for car makes and models.
Conclusion
Quen 3 Coder is an impressive open-source agentic code model that outperforms many open-source alternatives and competes with closed-source models. Its capabilities in front-end development, data visualization, and multi-language integration are noteworthy. The open-sourcing of Quen Code further enhances its accessibility and potential for community-driven development.
