I'm remaking my checkpoints into TIs since I am now able to generate them, which should make certain people happy :-)
There are several versions (by epochs). The longer the training goes the more accurate the model should be but also less flexible so pick and choose according to your current needs.
You can go through the examples and in the metadata you will see which version was used (since they are not sorted and uploaded per .pt version!)
As done with my first test embedding (Chrissie Mayr) - some were done as pure outputs and some were later hit with inpainting, but there was no photoshopping involved. What you see is what you get.
Also, I do not use 'restore faces' option because it changes the face structure too much and the person becomes less recognizable. But this is something that can be fixed in post.
