You didn’t include a scientific name, but I’m assuming you mean this speices. It’s not in the model (go to the About tab on the taxon page, look on the right-hand side). So you would have never gotten the correct species ID from CV.
Yeah, Seek doens’t use the current model that’s available on the website and the iNat mobile apps. It’s older (so fewer taxa), simplified, it has a higher confidence threshold (as it only shows one suggestion at a time), and it doesn’t take location into account when displaying suggestions.
Yeah, always good to keep in mind. It’s a suggestion, and iNat’s power is really in the community.
