DeepSeek × Claude Code Integration in Practice

Agent Tool Integration Overview

The DeepSeek API natively integrates with various mainstream AI Agent and programming assistant tools. No coding is required; simply modify the configuration file to use DeepSeek as the backend model. Currently supported tools include:

• Claude Code — Anthropic's terminal AI programming assistant
• GitHub Copilot — VS Code / JetBrains coding assistant
• OpenCode — Open-source AI programming tool
• Continue — VS Code / JetBrains AI plugin

Integrating Claude Code

Claude Code is currently the most popular terminal AI programming tool. After integrating DeepSeek, coding costs can be reduced by over 95%:

# Method 1: Environment variables (recommended)
export ANTHROPIC_API_KEY="sk-your-deepseek-api-key"
export ANTHROPIC_BASE_URL="https://api.deepseek.com/anthropic"

# Start Claude Code (automatically uses DeepSeek)
claude

# Method 2: Configuration file ~/.claude.json
{
  "apiKey": "sk-your-deepseek-api-key",
  "baseURL": "https://api.deepseek.com/anthropic"
}

Model Selection Strategy

Integrating GitHub Copilot / Continue

// Continue plugin configuration ~/.continue/config.json
{
  "models": [{
    "title": "DeepSeek V4 Flash",
    "provider": "openai",
    "model": "deepseek-v4-flash",
    "apiBase": "https://api.deepseek.com",
    "apiKey": "sk-your-key"
  }]
}

Cost Comparison: Real-world Scenarios

Notes

• Ensure your API Key has sufficient balance before first use.
• Some advanced features of Claude Code (such as Computer Use, Artifacts) are not yet supported by DeepSeek.
• It is recommended to start with the Flash model and manually switch to Pro for complex tasks.
