Personally, I still prefer working in my familiar environment, Photoshop. So I decided to write a plugin that lets me use these models directly inside Photoshop, following a workflow similar to "Generate Fill."
I've been using it with my team, and it works well so far. Because of rapid development, it currently only supports Photoshop 24.2.0 and above. A few teammates still use CS6, so I plan to add support for CS6 in the future.
With the latest Photoshop release, I noticed they added Nano Banana too. But I think my plugin still has an advantage when it comes to the speed of adopting new models, so I believe there's still a place for it.
