# 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 pt and safetensors formats
• 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 pt and safetensors formats
• 4-bit, 5-bit and 8-bit GGML models for llama.cpp

THE FILES IN MAIN BRANCH REQUIRES LATEST LLAMA.CPP (May 19th 2023 - commit 2d5db48)!

llama.cpp recently made another breaking change to its quantisation methods - https://github.com/ggerganov/llama.cpp/pull/1508

I have quantised the GGML files in this repo with the latest version. Therefore you will require llama.cpp compiled on May 19th or later (commit 2d5db48 or later) to use them.

For files compatible with the previous version of llama.cpp, please see branch previous_llama_ggmlv2.

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.ggmlv3.q5_0.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

Thanks, and how to contribute.

Thanks to the chirper.ai team!

I've had a lot of people ask if they can contribute. I enjoy providing models and helping people, and would love to be able to spend even more time doing it, as well as expanding into new projects like fine tuning/training.

If you're able and willing to contribute it will be most gratefully received and will help me to keep providing more models, and to start work on new AI projects.

Donaters will get priority support on any and all AI/LLM/model questions and requests, access to a private Discord room, plus other benefits.
