OpenAI

To work with OpenAI's models, you need to provide your OpenAI API key either in the OPENAI_API_KEY environment variable or via the --openai-api-key command line switch.

Aider has some built in shortcuts for the most popular OpenAI models and has been tested and benchmarked to work well with them:

python -m pip install -U aider-chat

export OPENAI_API_KEY=<key> # Mac/Linux
setx   OPENAI_API_KEY <key> # Windows, restart shell after setx

# Aider uses gpt-4o by default (or use --4o)
aider

# GPT-4o
aider --4o

# GPT-3.5 Turbo
aider --35-turbo

# o1-mini
aider --model o1-mini

# o1-preview
aider --model o1-preview

# List models available from OpenAI
aider --list-models openai/

You can use aider --model <model-name> to use any other OpenAI model. For example, if you want to use a specific version of GPT-4 Turbo you could do aider --model gpt-4-0125-preview.
