Integrate with Deep Code

Deep Code is an open-source terminal AI coding assistant for the DeepSeek-V4 model, supporting deep thinking, reasoning effort control, and Agent Skills.

GitHub: https://github.com/lessweb/deepcode-cli

1. Install Deep Code

Install Node.js 18+.
Run the following command in your terminal:

npm install -g @vegamo/deepcode-cli

Verify the installation:

deepcode --version

2. Configure Deep Code

Create ~/.deepcode/settings.json with your DeepSeek API key and model settings:

{
  "env": {
    "MODEL": "deepseek-v4-pro",
    "BASE_URL": "https://api.deepseek.com",
    "API_KEY": "sk-..."
  },
  "thinkingEnabled": true,
  "reasoningEffort": "max"
}

Get your API Key from the DeepSeek Platform.

Note: The same settings file is shared with the Deep Code VSCode extension.

Configuration options:
