-`GPT4All-13B-snoozy.q4_2.bin` | q4_2 | 4bit | 8.14GB | 10GB | Best compromise between resources, speed and quality |
-`GPT4All-13B-snoozy.q5_0.bin` | q5_0 | 5bit | 8.95GB | 11GB | Brand new 5bit method. Potentially higher quality than 4bit, at cost of slightly higher resources. |

-* The q4_0 file provides lower quality, but maximal compatibility. It will work with past and future versions of llama.cpp
-* The q4_2 file offers the best combination of performance and quality. This format is still subject to change and there may be compatibility issues, see below.
-* The q5_0 file is using brand new 5bit method released 26th April. This is the 5bit equivalent of q4_0.
-* The q5_1 file is using brand new 5bit method released 26th April. This is the 5bit equivalent of q4_1.

-## q4_2 compatibility
-
-q4_2 is a relatively new 4bit quantisation method offering improved quality. However they are still under development and their formats are subject to change.
 
-In order to use these files you will need to use recent llama.cpp code. And it's possible that future updates to llama.cpp could require that these files are re-generated.
+## REQUIRES LATEST LLAMA.CPP (May 12th 2023 - commit b9fd7ee)!
 
-If and when the q4_2 file no longer works with recent versions of llama.cpp I will endeavour to update it.
+llama.cpp recently made a breaking change to its quantisation methods.
 
-If you want to ensure guaranteed compatibility with a wide range of llama.cpp versions, use the q4_0 file.
+I have re-quantised the GGML files in this repo. Therefore you will require llama.cpp compiled on May 12th or later (commit `b9fd7ee` or later) to use them.
 
-## q5_0 and q5_1 compatibility
-
-These new methods were released to llama.cpp on 26th April. You will need to pull the latest llama.cpp code and rebuild to be able to use them.
-
-Don't expect any third-party UIs/tools to support them yet.
+The previous files, which will still work in older versions of llama.cpp, can be found in branch `previous_llama`.

 ## How to run in `llama.cpp`
 
 I use the following command line; adjust for your tastes and needs:
 
 ```
-./main -t 12 -m GPT4All-13B-snoozy.q4_2.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "Below is an instruction that describes a task. Write a response that appropriately completes the request.
