 I have quantised the GGML files in this repo with the latest version. Therefore you will require llama.cpp compiled on May 12th or later (commit `b9fd7ee` or later) to use them.
 
+If you are currently unable to update llama.cpp, eg because you use a UI which hasn't updated yet, you can find GGMLs compatible with the older llama.cpp code in branch `previous_llama`
