Qwen3-Coder-480B-A35B-Instruct Highlights

Qwen3-Coder-480B-A35B-Instruct represents Alibaba’s most ambitious step in open coding models. Built on a Mixture-of-Experts architecture with 480B total parameters and 35B active at once, it is designed for agentic coding—not just writing snippets of code, but supporting full programming workflows.

Core Strengths

• Agentic programming: Handles autonomous code generation, debugging, and repository-scale reasoning, comparable to premium closed-source models.
• Extended context: Natively supports 256K tokens, extendable to 1M with YaRN, enabling large-scale, multi-file codebase analysis.
• Multi-turn workflows: Excels at iterative development cycles: planning, tool use, processing feedback, and refining output step by step.
• Broad language coverage: Performs well across multiple programming languages and frameworks, from Python to JavaScript to enterprise stacks.

Qwen3-Coder doesn’t just generate functions in isolation—it is capable of repository-wide understanding and multi-turn collaboration, making it a strong candidate for teams working on complex software projects. With its open availability through platforms like Hugging Face and Novita AI, it bridges the gap between state-of-the-art research and practical developer workflows.

How to Run Qwen3-Coder-480B-A35B-Instruct in Claude Code

Step 1: Get Your API Key on Novita AI

Create an Novita AI account andThe first step is to generate an API key from the Novita AI platform. Then go to Key Management and select Add New Key.
This API Key acts as your access credential. Since it is only shown once, copy it immediately and save it in a secure place. It will be needed for the steps below.

Novita AI now supports all Claude Code models. You can view the full list of supported models here for details

Step 2: Install Claude Code

Claude Code requires Node.js. Make sure your local environment is running Node.js 18 or later by checking:

node --version

If everything looks good, install Claude Code globally with npm:

npm install -g @anthropic-ai/claude-code

A global installation makes the command available anywhere on your system, so you don’t have to worry about working directory restrictions.

Step 3: Configure Environment Variables

To route traffic through Novita AI and use Qwen3-Coder, you’ll need to set several environment variables. These specify the API endpoint, authentication token, and the model name.

Windows (Command Prompt):

set ANTHROPIC_BASE_URL=https://api.novita.ai/anthropic
set ANTHROPIC_AUTH_TOKEN=<Your-API-Key>
set ANTHROPIC_MODEL=qwen/qwen3-coder-480b-a35b-instruct
set ANTHROPIC_SMALL_FAST_MODEL=qwen/qwen3-coder-480b-a35b-instruct

Mac/Linux (Terminal):

export ANTHROPIC_BASE_URL="https://api.novita.ai/anthropic"
export ANTHROPIC_AUTH_TOKEN="<Your-API-Key>"
export ANTHROPIC_MODEL="qwen/qwen3-coder-480b-a35b-instruct"
export ANTHROPIC_SMALL_FAST_MODEL="qwen/qwen3-coder-480b-a35b-instruct"

Replace <Your-API-Key> with the token generated earlier. To switch to a different model, you can simply update the ANTHROPIC_MODEL environment variable.

Step 4: Start Claude Code

Navigate to the folder where your project files are located and launch Claude Code:

cd <your-project-directory>
claude .

The . tells Claude Code to run in the current directory. Once the prompt appears, you’re ready to interact with Qwen3-Coder directly in a natural language session.

Troubleshooting & Tips

• Token not found? Double-check that the environment variables are set in the same terminal session where you run claude ..
• Persistent configuration: On Mac/Linux, you can add the export commands to your .bashrc or .zshrc file; on Windows, use System Environment Variables to make them permanent.
• Switching models: Simply change the ANTHROPIC_MODEL variable to another model supported by Novita AI if you want to experiment.
