It's a good observations- there are so many unknowns about all these models. Every day there's a new wizard_uncensored_rhlf_alpaca_tuned_best_one_use_this_13B_4.6-bit_rqm.pth that gets released, it's almost impossible to know the relative merits and which are worth paying attention to.
How true. Every time I browse a model listing there are four word descriptions with little sense of versioning, provenance, hardware requirements, or any reason why I would choose one vs the other.
