It seems like the entire "product" here is just a ChatGPT system prompt: "combine this image of a person with this image of a dinosaur".
The only thing he needed to code was an NFT wrapper, which presumably is just forking an existing NFT wholesale.
The interesting, user-facing part of the project isn't code at all! It's just an HTML front end on someone else's image generator and a "pay me" button.
Very disappointing.
