validated() returns an array containing the request data that passed validation. It is the straightforward option when the complete validated payload is needed for the next step.

safe() returns a ValidatedInput object instead of an array. That object provides all(), only(), except(), merge(), collect(), and array access, making it convenient to intentionally select or extend validated data. For example, safe()->only(['name', 'email']) makes the allowed fields especially clear before creating or updating a model.
