# StableVicuna-13B-GGML

This is GGML format quantised 4bit and 5bit models of CarperAI's StableVicuna 13B.

It is the result of merging the deltas from the above repository with the original Llama 13B weights, and then quantising to 4bit and 5bit GGML for CPU inference using llama.cpp.

Repositories available

PROMPT TEMPLATE

This model works best with the following prompt template:

### Human: your prompt here
### Assistant:

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 12th or later (commit b9fd7ee or later) to use them.

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

Provided files

Name	Quant method	Bits	Size	RAM required	Use case
`stable-vicuna-13B.ggmlv3.q4_0.bin`	q4_0	4bit	8.14GB	10.5GB	4bit.
`stable-vicuna-13B.ggmlv3.q4_1.bin`	q4_1	4bit	8.95GB	11.0GB	4-bit. Higher accuracy than q4_0 but not as high as q5_0. However has quicker inference than q5 models.
`stable-vicuna-13B.ggmlv3.q5_0.bin`	q5_0	5bit	8.95GB	11.0GB	5bit. Higher accuracy, higher resource usage and slower inference.
`stable-vicuna-13B.ggmlv3.q5_1.bin`	q5_1	5bit	9.76GB	12.25GB	5bit. Higher accuracy than q5_0, but again higher resource usage and slower inference.
`stable-vicuna-13B.ggmlv3.q8_0.bin`	q8_0	8bit	14.6GB	17GB	8-bit. Almost indistinguishable from float16. Huge resource use and slow. Not recommended for normal use.

How to run in `llama.cpp`

I use the following command line; adjust for your tastes and needs:

./main -t 18 -m stable-vicuna-13B.ggmlv3.q4_0.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -r "### Human:" -p "### Human: write a story about llamas ### Assistant:"

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.

How to run in `text-generation-webui`

GGML models can be loaded into text-generation-webui by installing the llama.cpp module, then placing the ggml model file in a model folder as usual.

Further instructions here: text-generation-webui/docs/llama.cpp-models.md.

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.

Original StableVicuna-13B model card

Model Description

StableVicuna-13B is a Vicuna-13B v0 model fine-tuned using reinforcement learning from human feedback (RLHF) via Proximal Policy Optimization (PPO) on various conversational and instructional datasets.

Model Details

Trained by: Duy Phung of CarperAI
Model type: StableVicuna-13B is an auto-regressive language model based on the LLaMA transformer architecture.
Language(s): English
Library: trlX
License for delta weights: CC-BY-NC-SA-4.0
- Note: License for the base LLaMA model's weights is Meta's non-commercial bespoke license.
Contact: For questions and comments about the model, visit the CarperAI and StableFoundation Discord servers.

Hyperparameter	Value
$n_\text{parameters}$	13B
$d_\text{model}$	5120
$n_\text{layers}$	40
$n_\text{heads}$	40

Training

Training Dataset

StableVicuna-13B is fine-tuned on a mix of three datasets. OpenAssistant Conversations Dataset (OASST1), a human-generated, human-annotated assistant-style conversation corpus consisting of 161,443 messages distributed across 66,497 conversation trees, in 35 different languages; GPT4All Prompt Generations, a dataset of 400k prompts and responses generated by GPT-4; and Alpaca, a dataset of 52,000 instructions and demonstrations generated by OpenAI's text-davinci-003 engine.

The reward model used during RLHF was also trained on OpenAssistant Conversations Dataset (OASST1) along with two other datasets: Anthropic HH-RLHF, a dataset of preferences about AI assistant helpfulness and harmlessness; and Stanford Human Preferences Dataset a dataset of 385K collective human preferences over responses to questions/instructions in 18 different subject areas, from cooking to legal advice.

Training Procedure

CarperAI/stable-vicuna-13b-delta was trained using PPO as implemented in trlX with the following configuration:

Hyperparameter	Value
num_rollouts	128
chunk_size	16
ppo_epochs	4
init_kl_coef	0.1
target	6
horizon	10000
gamma	1
lam	0.95
cliprange	0.2
cliprange_value	0.2
vf_coef	1.0
scale_reward	None
cliprange_reward	10
generation_kwargs
max_length	512
min_length	48
top_k	0.0
top_p	1.0
do_sample	True
temperature	1.0

Use and Limitations

Intended Use

This model is intended to be used for text generation with a focus on conversational tasks. Users may further fine-tune the model on their own data to improve the model's performance on their specific tasks in accordance with the non-commercial license.

Limitations and bias

The base LLaMA model is trained on various data, some of which may contain offensive, harmful, and biased content that can lead to toxic behavior. See Section 5.1 of the LLaMA paper. We have not performed any studies to determine how fine-tuning on the aforementioned datasets affect the model's behavior and toxicity. Do not treat chat responses from this model as a substitute for human judgment or as a source of truth. Please use responsibly.
