I might have a go at installing one, what is a good source or install at the moment?
If you just want to play for a bit: llamafile
If you want granular control with ease of execution in exchange for having to figure out what the settings mean and figure out which weights to download: koboldcpp. (check out bartowski on huggingface for the weights)
These are all based on llamacpp as a backend, by the way.
