It doesn't matter. If someone has the same idea then they can use AI the same way you did to recreate it. Keeping it a secret benefits no one other than the AI providers b/c now they can charge money for giving someone else "your" code. The AI providers don't care about license restrictions so it's the perfect way to launder code. If you want credit for something then you'll have to claim it publicly b/c the AI providers sure as hell are not going to give you any credit.
