Aider

Reviewed by Proof · Updated

Definition

Aider is an open-source AI pair-programming tool for the terminal that can use luv13 as an OpenAI-compatible endpoint.

Key takeaways

  • Aider reads the endpoint from OPENAI_API_BASE and the key from OPENAI_API_KEY.
  • Set OPENAI_API_BASE to https://api.luv13.ai/v1 and OPENAI_API_KEY to your luv13 key.
  • Put openai/ in front of the model id, so luv13's luv13/glm-5.3-flash becomes openai/luv13/glm-5.3-flash.
  • Aider may warn that it doesn't know the model's settings. That's expected for models outside its built-in list.
  • These names come from Aider's official docs on OpenAI-compatible APIs.

Setup

Install Aider using the method in its docs, for example:

python -m pip install aider-install
aider-install

Set the endpoint and key. On macOS or Linux:

export OPENAI_API_BASE=https://api.luv13.ai/v1
export OPENAI_API_KEY=$LUV13_API_KEY

On Windows, use setx OPENAI_API_BASE https://api.luv13.ai/v1 and setx OPENAI_API_KEY <your key>, then open a new terminal.

Then start Aider inside your project:

cd /path/to/your/project
aider --model openai/luv13/glm-5.3-flash

Using a config file

Aider can also read its settings from a .aider.conf.yml file:

openai-api-base: https://api.luv13.ai/v1
model: openai/luv13/glm-5.3-flash

Keep the key in the environment instead of this file. See YAML Config.

About the model warning

Aider keeps details, such as context size, for models it knows. For other models it shows a warning and uses defaults. luv13's model list doesn't publish context lengths, so there's no official value to add. See Context Window.

Check your settings first

curl https://api.luv13.ai/v1/chat/completions \
  -H "Authorization: Bearer $LUV13_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "luv13/glm-5.3-flash", "messages": [{"role": "user", "content": "Hi"}]}'
