Oobabooga's web UI loads models in half a dozen formats, exposes every sampler, and has extensions for voice, character cards, long-term memory and much else. If you want to compare quantisation formats or run something exotic, this is where you can.

The breadth is also the cost: the installer pulls a large dependency tree, and the first run involves choosing a loader you have not heard of.

Worth knowing before you start

Large installation The dependency tree is substantial and occasionally fragile across updates.
Choice of loader is not obvious Picking the wrong backend for your quantisation format is the classic first-run failure.
