Environment variables
Our examples use OpenAI by default. You'll need to set up your Open AI key like so:
export OPENAI_API_KEY="sk-......" # Replace with your key from https://platform.openai.com/account/api-keys
If you want to have it automatically loaded every time, add it to your .zshrc/.bashrc
.
WARNING: do not check in your OpenAI key into version control.
