I'd be interested to know how your model performs if it is trained only on your own work.
Assuming you haven't taken a photo a second for your entire life, then I suspect you'll struggle to make something even close to what's available publically, due to lack of training data.
Obviously not, but the point isn't to make a public model, but to make something out of my own - my question was how does ownership work? At some point, somebody is going to be making something out of their own massive archive.
