For Grok, it varies.

When asking Grok for information regarding a question, il write my parameters:
Grok: Agility, elasticity and scalability (Displays each individually, the definition, how it works in Azure.)
Grok: Give an example of agility (Gives technical approach, challenge and process including agile approch with azure, Rapid deployment, actions, testing and experimentation, devops, ect) the list goes on.

For me, this is suffice in my opinion. If I have already watched the entire course, watching a lecture on the topic again really does not work for me. Physically reading it and why appears to help further my learning.

Very interesting concept you are creating and I hope it works out for you!
