This is Llama2-22b by chargoddard in a couple of GGML formats. I have no idea what I'm doing so if something doesn't work as it should or not at all that's likely on me, not the models themselves.
A second model merge has been released and the GGML conversions for that can be found here.
While I haven't had any issues so far do note that the original repo states "Not intended for use as-is - this model is meant to serve as a base for further tuning".
