That's one problem with these DiRs. Since the model needs to be loaded using llama.cpp (and llama.cpp uses model path), the DiR either needs to accept model path as model name (type mismatch), or just assume that your models are in a certain path and then receive model file name as model name (better). But that means the DiR needs to control the model loader (and in most cases they actually download and build that automatically after install). But I'd rather build my own llama.cpp and just have a nice interface to it that stays out of my way.
