• curl (for downloading nvm and making API calls)
• A DeepSeek API key (get one at platform.deepseek.com)

Quick Installation

1. Get your DeepSeek API key:

   • Visit DeepSeek Open Platform
   • Go to User Center (top right) → API Key Management → Create New API Key

2. Run the installation script:

   bash -c "$(curl -fsSL https://raw.githubusercontent.com/2404589803/deepseek-cc/main/install-deepseek.sh)"

3. Enter your API key when prompted

4. Restart your terminal or run:

   source ~/.bashrc  # or ~/.zshrc, ~/.profile, etc.

5. Start using Claude Code with DeepSeek:

   claude

Environment Variables

The script configures the following environment variables to redirect Claude Code to use DeepSeek API:

• ANTHROPIC_BASE_URL: https://api.deepseek.com
• ANTHROPIC_API_KEY: Your DeepSeek API key
• DEEPSEEK_BASE_URL: https://api.deepseek.com
• DEEPSEEK_API_KEY: Your DeepSeek API key
• OPENAI_BASE_URL: https://api.deepseek.com (for OpenAI SDK compatibility)
• OPENAI_API_KEY: Your DeepSeek API key

Available Models

• deepseek-chat: DeepSeek-V3-0324 (General chat model)
• deepseek-reasoner: DeepSeek-R1-0528 (Reasoning model)

How It Works

DeepSeek CC works by:

1. Installing Claude Code (Anthropic's official CLI tool)
2. Configuring environment variables to redirect API calls from Anthropic to DeepSeek
3. Since DeepSeek uses OpenAI-compatible API format, Claude Code works seamlessly
4. All your conversations are processed through DeepSeek's models at DeepSeek's pricing

Usage

After installation, simply use Claude Code as normal:

claude

Claude Code will now use DeepSeek's API instead of Anthropic's, giving you:

• Access to DeepSeek's powerful models
• Lower costs compared to Anthropic's pricing
• Same Claude Code interface and features
• All Claude Code commands and functionality

Manual API Usage

You can also use the DeepSeek API directly:

Using curl

curl https://api.deepseek.com/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DEEPSEEK_API_KEY" \
  -d '{
    "model": "deepseek-chat",
    "messages": [
      {"role": "system", "content": "You are a helpful assistant."},
      {"role": "user", "content": "Hello!"}
    ],
    "stream": false
  }'

Using Node.js with OpenAI SDK

import OpenAI from 'openai';

const client = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
  baseURL: process.env.OPENAI_BASE_URL
});

const completion = await client.chat.completions.create({
  model: 'deepseek-chat',
  messages: [
    { role: 'system', content: 'You are a helpful assistant.' },
    { role: 'user', content: 'Hello!' }
  ]
});

console.log(completion.choices[0].message.content);
