What is the difference between variant generation and variant selection?
Variant selection is the model most traditional personalization platforms use. The team manually builds a finite number of page variants, and the system picks the most appropriate one for each visitor based on predefined rules. Variant generation is a newer model where AI agents compose the right experience from the visitor's signal in real time, without needing a pre-built variant for every possible combination. The ceiling of variant selection is always the team's capacity to build and maintain variants. Variant generation removes that ceiling entirely because the experience comes from the signal, not from a library someone built in advance.
