# Using in Claude Code

> Integrate SiliconFlow's AI models with Claude Code for enhanced development experience

<Note>
  This integration guide is compatible with macOS and Linux systems. Windows users should use WSL (Windows Subsystem for Linux).
</Note>

## Overview

Claude Code is a command-line AI assistant that helps with coding tasks. By integrating it with SiliconFlow, you can access powerful AI models for code generation, debugging, and analysis directly from your terminal.

## Prerequisites

* macOS or Linux operating system (or WSL on Windows)
* Terminal access with bash shell
* Valid SiliconFlow API key ([Get your API key](https://cloud.siliconflow.com/account/ak))
* Internet connection for downloading the setup script

## Method 1: Automated Setup (Recommended)

### Step 1: Run the Installation Script

Execute the automated setup script in your terminal:

```bash theme={null}
bash -c "$(curl -fsSL https://sf-maas.s3.us-east-1.amazonaws.com/sample/ccsf_v251226.sh)"
```

<Warning>
  Always review scripts from external sources before execution. This script will configure your environment variables and Claude Code settings.
</Warning>

### Step 2: Configure API Authentication

When prompted, enter your SiliconFlow API key:

</Frame>

<Tip>
  You can find your API key in the [SiliconFlow Console](https://cloud.siliconflow.com/account/ak). Keep it secure and never share it publicly.
</Tip>

### Step 3: Select AI Model

Choose your preferred model using the arrow keys, or select **Custom** to specify your own model:

</Frame>

### Step 4: Apply Configuration

Follow the on-screen instructions to finalize the setup:

1. Copy the provided command
2. Restart your terminal session
3. Run the copied command to apply the configuration

</Frame>

### Step 5: Start Using Claude Code

Launch Claude Code with the following command:

```bash theme={null}
claude
```

You can now interact with your selected AI model directly from the terminal for coding assistance.

## Method 2: Manual Configuration

For advanced users who prefer manual setup or need custom configurations:

### Environment Variables Setup

Configure the required environment variables in your shell profile (`.bashrc`, `.zshrc`, or `.profile`):

```bash theme={null}
# SiliconFlow API Configuration
export ANTHROPIC_BASE_URL="https://api.siliconflow.com/"
export ANTHROPIC_MODEL="your-preferred-model"     # Replace with your preferred model
export ANTHROPIC_API_KEY="sk-your-api-key-here"   # Replace with your actual API key
```

### Apply Configuration

Reload your shell configuration:

```bash theme={null}
# For bash users
source ~/.bashrc

# For zsh users  
source ~/.zshrc
```

## Model Management

### Switching Models

Claude Code currently supports one active model at a time. To change models:

**Option A: Re-run the automated setup**

```bash theme={null}
bash -c "$(curl -fsSL https://sf-maas.s3.us-east-1.amazonaws.com/sample/ccsf_v251226.sh)"
```

**Option B: Update environment variable manually**

```bash theme={null}
export ANTHROPIC_MODEL="new-model-name"
```

### Available Models

Explore available models at [cloud.siliconflow.com/models](https://cloud.siliconflow.com/models) to find the one that best fits your needs.

## Usage Tips

<Tip>
  **Best Practices:**

  * Use specific, detailed prompts for better code suggestions
  * Break complex tasks into smaller, manageable requests
  * Review generated code before implementation
  * Monitor your usage in the [SiliconFlow Console](https://cloud.siliconflow.com/console)
</Tip>

## Troubleshooting

### Common Issues

**Authentication Error:**

```bash theme={null}
# Verify your API key is correctly set
echo $ANTHROPIC_API_KEY
```

**Model Not Found:**

```bash theme={null}
# Check if the model name is correct
echo $ANTHROPIC_MODEL
```

**Connection Issues:**

```bash theme={null}
# Test API connectivity
curl -H "Authorization: Bearer $ANTHROPIC_API_KEY" https://api.siliconflow.com/v1/models
```
