What is the difference between the cotton gin of Eli Whitney and the modern cotton gin

A cotton gin is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.[1] The fibers are then processed into various cotton goods such as linens, while any undamaged cotton is used largely for textiles like clothing. The separated seeds may be used to grow more cotton or to produce cottonseed oil. The modern cotton gin is made from seeds it grows from seeds unlike the cotton gin that separates the seeds
