What you suggest is generating models with AI. I haven't heard of this before.

But my understanding is they already used AI to increase the resolution of the user interface and hotbar icons ahead of the release of the PS5 version, then adjusted any that looked flawed on their own. I don't know if they used it for some textures in ARR, but I noticed a difference before flying released.

Final Fantasy XIV’s UI was originally intended for a 720p display, so we worked to up-res those original images for the PS5 version. Naturally, going through each and every item, equipment, and ability icon by hand would have been impossible to achieve in a short amount of time, so we incorporated a few tricks to find ways to be efficient; for example, we utilized AI tools to boost the resolution and tweaked any parts of the icons that needed it by hand.

Aside from the UI elements, things like the font has a higher resolution now as well, so overall these elements will look a lot smoother.”
We are thinking of eventually upgrading in-game textures in phases and are starting initial preparations for that update.

However, we do need to keep in mind that other platforms, including the PlayStation 4 version, are still in service. Since FFXIV is an MMO, we need to place some emphasis on being able to simultaneously render player characters and their equipment, while still ensuring everything works smoothly. We do need to take care when planning major updates like this and start with testing and verifying it all works well.

Plus, assets that we created nearly ten years ago didn’t factor in the possibility of being displayed at the high resolutions available to us today, so we have to think about how to revise quite a massive amount of assets efficiently.
So look forward to more AI work in 7.0.
