Actually, the score scaling is a very tough subject for a public thing. We received some comments saying that Keegan is wayy too harsh, it seems people expect their everyday picture to score 7-8 (we've been told it'd be a big problem in the US especially, I can't judge on that as not living there tho :/), while we feel that Keegan s generally a bit too generous for Europe standards.
I might be a particularly tough sell since I grew up in the US but have been living in Europe for quite some time now ;)
I think what you're seeing on is AI hype in action. The marketing of Keegan suggests that it's AI should be capturing some of what is usually perceived as subjective taste (e.g. whether or not the image is "interesting"). This ends up disappointing because the AI (which is clearly an incredible technical feat) is really just capturing objective elements of composition.
Perhaps you just need to fine-tune the language so as to do some expectation management?
He seems to like it. 6.5/10 for a generic, raunchy shot.
The point is that pornography is probably the least-composed imaging one can find. It feels like this bot is just spitting out random compliments.
