The Fastest Way to Get Started

If you already have Python 3.8-3.13 installed:

python -m pip install aider-install
aider-install

# Change directory into your codebase
cd /to/your/project

This creates a separate Python environment specifically for Aider, ensuring clean dependency management.

Then connect to your preferred LLM:

# DeepSeek
aider --model deepseek --api-key deepseek=<key>

# Claude 3.7 Sonnet
aider --model sonnet --api-key anthropic=<key>

# o3-mini
aider --model o3-mini --api-key openai=<key>
