They keep adding stuff

Features are nice, but the model's inherent performance is what really matters. Currently, it's exclusive to koji and luca models, but they plan to expand it sequentially to the zeta model, so let's wait a little longer, hmm!

I don't think they'll try to improve the model performance because of the paid model, though.

Seriously, they're releasing all sorts of stuff lol. But since the base model is free, don't expect too much ㅠ They got heavily criticized, users canceled their passes, and a lot of people left, so it's only slightly better now after some fixes... If you have to use Koji or Luca anyway, other chat options are much better. You can get rewards from check-in events and save them up to chat for free. No ads either.
