Koala: A Dialogue Model for Academic Research
This repo contains the weights of the Koala 7B model produced at Berkeley. It is the result of combining the diffs from https://huggingface.co/young-geng/koala with the original Llama 7B model.
This version has then been quantized to 4-bit and 5-bit GGML for use with llama.cpp.
My Koala repos
I have the following Koala model repositories available:
13B models:
- Unquantized 13B model in HF format
- GPTQ quantized 4bit 13B model in
ptandsafetensorsformats - 4-bit, 5-bit and 8-bit GGML models for
llama.cpp
7B models:
- Unquantized 7B model in HF format
- Unquantized 7B model in GGML format for llama.cpp
- GPTQ quantized 4bit 7B model in
ptandsafetensorsformats - 4-bit, 5-bit and 8-bit GGML models for
llama.cpp
REQUIRES LATEST LLAMA.CPP (May 12th 2023 - commit b9fd7ee)!
llama.cpp recently made a breaking change to its quantisation methods.
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.
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 18 -m koala-7B-4bit-128g.GGML.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "BEGINNING OF CONVERSATION:
USER: <PROMPT GOES HERE>
GPT:"
Change -t 18 to the number of physical CPU cores you have. For example if your system has 8 cores, 16 threads, use -t 8.
This model should be able to run in 8GB RAM without swapping.
How the Koala delta weights were merged
The Koala delta weights were originally merged using the following commands, producing koala-7B-HF:
git clone https://github.com/young-geng/EasyLM
git clone https://huggingface.co/nyanko7/LLaMA-7B
mkdir koala_diffs && cd koala_diffs && wget https://huggingface.co/young-geng/koala/resolve/main/koala_7b_diff_v2
cd EasyLM
