The Rundown: Alibaba's new Qwen 3 Coder offers competitive coding capabilities that match premium models like Claude Sonnet 4, featuring both browser-based chat and CLI access for developers.

🧰 Who is this useful for:

• Developers seeking cost-effective coding assistance
• Teams wanting open-source alternatives to paid AI tools
• Programmers who prefer terminal-based workflows
• Students learning to code with AI assistance

STEP 1: Access the Browser Interface

Head over to Qwen Chat and create a free account. Once logged in, locate the model selector and ensure you have “Qwen3-Coder” selected, as this is the latest and most powerful coding model available. The interface will look familiar if you've used ChatGPT or similar chat-based AI tools.

The browser version offers additional features beyond coding, including image generation and video generation capabilities. However, for pure coding tasks, Qwen 3 Coder excels without needing the “thinking” process available in other models.

STEP 2: Test the Preview Capability

Start with a simple project to understand the model's capabilities. Try prompting: “Create a Twitter clone in one file” to test the preview functionality. The model will generate code that you can immediately preview within the chat interface using the “Preview” button.

This feature allows you to see your code running in real-time without switching between different applications or setting up development environments.

STEP 3: Refine and Expand Your Project

Once you have a basic version running, use follow-up prompts to enhance your application. For example, prompt: “Add images and make it more complete” to significantly expand the functionality.

The model can transform a simple 116-line application into a comprehensive 1,000+ line project with just one additional prompt, demonstrating its ability to understand context and build upon previous work.

STEP 4: Install the CLI for Terminal Access

For developers who prefer working in the terminal, install the CLI tool by running:

npm install -g qwen-code/qwen-code

Navigate to your desired project directory and invoke the agent by simply typing qwen in your terminal. On first use, you'll be prompted to select a theme and authenticate with an API key.

The Qwen CLI functions similarly to Claude Code and Gemini CLI, allowing you to ask questions, edit files, create new projects, and fix bugs directly from your terminal environment.

Pro tip: The model offers up to 1 million tokens for free usage, making it an excellent choice for extensive coding sessions. Its open-source nature means you can also run it locally if needed.
