What’s the difference between Clay 101 and the Clay Enterprise Cohort?

Hi there - is there any documentation on the difference between Clay 101 or Clay Enterprise Cohort? We're working to get folks on our RevOps team ramped up on Clay, and wanted to make sure to recommend the right Cohort to them. Clay 101 was what I was going to suggest, but wasn't sure if the 101 is now augmented via university, and then the Enterprise cohort. Appreciate the help!
