Hi all,

Just started the new course and wanted to get going and on setup page you are saying:

Set up OpenAI API key

If you don’t have an OpenAI API key, you can sign up here.

but below in env file you are then having:

# Required for model usage
ANTHROPIC_API_KEY=your_anthropic_api_key_here

so not sure if we need openai at all or we use anthropic API here.

In the notebooks, some exercises use the OpenAI models and other exercises use the Anthropic (Claude) models, so you ned both APIs keys.

You can use either. If you have OpenAI key you can use any openai mode, if you have anthropic api key, you can use anthropic models

I had an invalid OpenAI API key so switched to using Anthropic in all notebooks, seems to be working fine.
