I may be misconstruing you here, and I apologize if I am, but it sounds like you think the AI is constantly learning, which unfortunately isn’t the case. It takes months to train a model, and the current training run was started a few months ago and is not yet complete. We plan on training about two models a year.
For taxa that have a lot of photos, I find that it’s pretty good at distinguishing between some pretty similar-looking species, such as Sceloporus occidentalis and Sceloporus gracilis. Not foolproof, of course, but I’m pretty surprised at times. So much depends on having lots and lots of correctly identified photos, which is less likely for corals I would imagine.
