Since talking images, are there any AI models that can output real transparent gifs/pngs?
And not a (botched) fake white/gray grid background that is commonly used to visualize transparency?
You can output to a plain background and use any number of tools to mask it.
ChatGPT's image generator has been able to do this since last year. That NBP still can't is baffling. They should at least train it to respond to requests for transparency with a solid colour pink background.
