Multi-edition NFT, allows you to mint multiple NFTs with different edition ids but referring to the same media and collection metadata. Since the collection metadata represents token properties, all tokens in single metadata can only be identified by the edition ID and have the same properties except that. Of course, you can also make all the tokens unique by setting the count limit as one. See more details and APIs from this page.
Generative NFTallows minting multiple NFTs as a collection with different properties for each token. Unlike the multi-edition NFT model, you can assign specific metadata and media to each edition. For example, suppose you publish a collection of art NFTs using multiple media files with slightly distinguished artistic characteristics and differentiated properties such as grade. In that case, you can use the Generative NFT model.
