Using a .env file

You can use a .env file to store various keys and other settings for the models you use with aider.

Aider will look for a .env file in the root of your git repo or in the current directory. You can give it an explicit file to load with the --env-file <filename> parameter.

Here is an example .env file:

OPENAI_API_KEY=<key>
ANTHROPIC_API_KEY=<key>
GROQ_API_KEY=<key>
OPENROUTER_API_KEY=<key>

AZURE_API_KEY=<key>
AZURE_API_VERSION=2023-05-15
AZURE_API_BASE=https://example-endpoint.openai.azure.com

OLLAMA_API_BASE=http://127.0.0.1:11434
