As a paid Lumo subscriber, there's no kind way of putting this -- Lumo feels really dumb compared to any of the other mainstream LMMs. It struggles to follow and keep up with conversations once they exceed a handful of back-and-forth exchanges, it frequently hallucinates and confabulates, it gets easily confused to the point where I'm having to help it rather than it helping me, and it just generally feels like conversing with a well-meaning but addled, confused elderly person. As such, I use it sparingly to brainstorm ideas or just have quick chats but cannot rely on it for anything requiring any degree of accuracy or sustained comprehension.
Models get better with bigger training sets, more parameters and larger context windows, so to the extent possible while preserving the privacy focus that makes it unique, please make Lumo smarter. I want to remain a Lumo subscriber, but I'm getting so little value out of it and find it such a frustrating experience much of the time that I simply don't think I can justify spending money on it much longer without some significant, noticeable improvements.
