I tried dwarfstar when llama.cpp DSV4 support was still very weak, and while it worked, I didn't see anything that would make me want to stick with it vs llama.cpp. llama.cpp is simply better with its awesome built-in webui, router and server APIs and certainly support much more models and quantizations than dwarfstar.

Since then, I started maintaining my own vibe coded dsv4 branch with metal optimizations, so I actually get much better metal performance on my llama.cpp branch than on dwarfstar (plus all the extra llama.cpp features). Here it is in case you want to give it a shot: https://github.com/tarruda/llama.cpp/tree/qwen4exp-dsv4-opti...
