Integrate with Pi

Pi (pi-mono) is a minimal, aggressively extensible terminal coding harness. It adapts to your workflows through TypeScript extensions, skills, prompt templates, and themes — with tree-structured sessions and 15+ built-in providers.

1. Install Pi

• Install Node.js.
• Run the following command in your terminal to install Pi:

npm install -g @earendil-works/pi-coding-agent

• After installation, run the following command. If the version number is displayed, the installation is successful:

pi --version

Note: Linux / macOS users can also install via the official script:

curl -fsSL https://pi.dev/install.sh | sh

2. Configure DeepSeek Provider

Pi supports custom providers via models.json. Add DeepSeek as an OpenAI-compatible provider:

• Linux / macOS: ~/.pi/agent/models.json
• Windows: %USERPROFILE%\.pi\agent\models.json

Get your API Key from the DeepSeek Platform.

Set the environment variable:

Linux / Mac users:

export DEEPSEEK_API_KEY="<your DeepSeek API Key>"

Windows users:

$env:DEEPSEEK_API_KEY="<your DeepSeek API Key>"

3. Run and Select Model

• Enter the project directory and execute the pi command:

cd /path/to/my-project
pi

• Type /model to open the model switcher.
• Select deepseek and choose DeepSeek-V4-Pro or DeepSeek-V4-Flash.
• Start coding with your minimal terminal harness.

For more configuration options, see the Pi models documentation.
