I uploaded 16 photos to train the model and I am impressed by the "photos" created by PhotoGPT. Some of them are pretty close to a real photo of that person. A few pictures were also way off the mark. But you can chose the ones that fit and let the AI create something simelar, that way you easily get good results. You can also experiment with the prompts and change the images step by step. I am still learning how to use this tool, but so far it does meet my expectations even with tier 1.
