Step 1: Log in to your account and click on the Model Library button.

Step 2: Choose Your Model

Browse through the available options and select the model that suits your needs.

Step 3: Start Your Free Trial

Begin your free trial to explore the capabilities of the selected model.

Step 4: Get Your API Key

To authenticate with the API, we will provide you with a new API key. Entering the “Settings“ page, you can copy the API key as indicated in the image.

Step 5: Install the API

Install API using the package manager specific to your programming language.

After installation, import the necessary libraries into your development environment. Initialize the API with your API key to start interacting with Novita AI LLM. This is an example of using chat completions API for python users.

pip install 'openai>=1.0.0'
from openai import OpenAI
  
client = OpenAI(
    base_url="https://api.novita.ai/v3/openai",
    api_key="",
)

model = "qwen/qwen3-coder-480b-a35b-instruct"
stream = True # or False
max_tokens = 131072
system_content = ""Be a helpful assistant""
temperature = 1
top_p = 1
min_p = 0
top_k = 50
presence_penalty = 0
frequency_penalty = 0
repetition_penalty = 1
response_format = { "type": "text" }

chat_completion_res = client.chat.completions.create(
    model=model,
    messages=[
        {
            "role": "system",
            "content": system_content,
        },
        {
            "role": "user",
            "content": "Hi there!",
        }
    ],
    stream=stream,
    max_tokens=max_tokens,
    temperature=temperature,
    top_p=top_p,
    presence_penalty=presence_penalty,
    frequency_penalty=frequency_penalty,
    response_format=response_format,
    extra_body={
      "top_k": top_k,
      "repetition_penalty": repetition_penalty,
      "min_p": min_p
    }
  )

if stream:
    for chunk in chat_completion_res:
        print(chunk.choices[0].delta.content or "", end="")
else:
    print(chat_completion_res.choices[0].message.content)

Qwen 3 Coder 480B A35B with Claude Code

Step 1: Installing Claude Code

Before installing Claude Code, ensure your system meets the minimum requirements. Node.js 18 or higher must be installed on your local environment. You can verify your Node.js version by running node --version in your terminal.

For Windows

Open Command Prompt and execute the following commands:

npm install -g @anthropic-ai/claude-code
npx win-claude-code@latest

The global installation ensures Claude Code is accessible from any directory on your system. The npx win-claude-code@latest command downloads and runs the latest Windows-specific version.

For Mac and Linux

Open Terminal and run:

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

Mac users can proceed directly with the global installation without requiring additional platform-specific commands. The installation process automatically configures the necessary dependencies and PATH variables.

Step 2 :Setting Up Environment Variables

Environment variables configure Claude Code to use Kimi-K2 through Novita AI’s API endpoints. These variables tell Claude Code where to send requests and how to authenticate.

For Windows

Open Command Prompt and set the following environment variables:

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

Replace <Novita API Key> with your actual API key obtained from the Novita AI platform. These variables remain active for the current session and must be reset if you close the Command Prompt.

For Mac and Linux

Open Terminal and export the following environment variables:

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

Step 3: Starting Claude Code

With installation and configuration complete, you can now start Claude Code in your project directory. Navigate to your desired project location using the cd command:

cd <your-project-directory>
claude .

The dot (.) parameter instructs Claude Code to operate in the current directory. Upon startup, you’ll see the Claude Code prompt appear in an interactive session.

This indicates the tool is ready to receive your instructions. The interface provides a clean, intuitive environment for natural language programming interactions.

Step 4: Using Claude Code in VSCode or Cursor

Claude Code integrates seamlessly with popular development environments. It enhances your existing workflow rather than replacing it.

You can use Claude Code directly in the terminal within VSCode or Cursor. This maintains access to your familiar development tools while leveraging AI assistance.

Additionally, Claude Code plugins are available for both VSCode and Cursor. These plugins provide deeper integration with these editors, offering inline AI assistance, code suggestions.

Qwen Code is developed on top of Gemini Code, but we have adapted the prompts and tool-calling protocols to maximize Qwen3-Coder’s performance in agentic coding tasks.

Step 1: Install Qwen Code

Prerequisites: Ensure you have Node.js version 20 or higher installed. You can download it from the official Node.js website.

Install the package globally:

npm install -g @qwen-code/qwen-code

Step 2: Configure Environment Variables

For Windows (Command Prompt):

set OPENAI_API_KEY=Your_Novita_API_Key
set OPENAI_BASE_URL=https://api.novita.ai/v3/openai
set OPENAI_MODEL=qwen/qwen3-coder-480b-a35b-instruct

For Linux and Mac (Bash):

export OPENAI_API_KEY="Your_Novita_API_Key"
export OPENAI_BASE_URL="https://api.novita.ai/v3/openai"
export OPENAI_MODEL="qwen/qwen3-coder-480b-a35b-instruct"

Step 3: Start Coding

Once configured, you can start using Qwen Code with your chosen Novita AI model. The tool will now utilize the specified model for all coding assistance tasks.

cd <your-project-directory>
qwen .

Qwen 3 Coder 480B A35B is easy to use and extremely powerful. You can run it from the command line or your favorite editor, and it’s great for big coding projects or everyday tasks.
