<summary>Explanation of GPTQ parameters</summary>
|
108 |
+
|
109 |
+
- Bits: The bit size of the quantised model.
|
110 |
+
- GS: GPTQ group size. Higher numbers use less VRAM, but have lower quantisation accuracy. "None" is the lowest possible value.
|
111 |
+
- Act Order: True or False. Also known as `desc_act`. True results in better quantisation accuracy. Some GPTQ clients have had issues with models that use Act Order plus Group Size, but this is generally resolved now.
|
112 |
+
- Damp %: A GPTQ parameter that affects how samples are processed for quantisation. 0.01 is default, but 0.1 results in slightly better accuracy.
|
113 |
+
- GPTQ dataset: The calibration dataset used during quantisation. Using a dataset more appropriate to the model's training can improve quantisation accuracy. Note that the GPTQ calibration dataset is not the same as the dataset used to train the model - please refer to the original model repo for details of the training dataset(s).
|
114 |
+
- Sequence Length: The length of the dataset sequences used for quantisation. Ideally this is the same as the model sequence length. For some very long sequence models (16+K), a lower sequence length may have to be used. Note that a lower sequence length does not limit the sequence length of the quantised model. It only impacts the quantisation accuracy on longer inference sequences.
|
115 |
+
- ExLlama Compatibility: Whether this file can be loaded with ExLlama, which currently only supports Llama and Mistral models in 4-bit.

## How to download, including from branches
|
132 |
+
|
133 |
+
### In text-generation-webui
|
134 |
+
|
135 |
+
To download from the `main` branch, enter `TheBloke/stablelm-zephyr-3b-GPTQ` in the "Download model" box.
|
136 |
+
|
137 |
+
To download from another branch, add `:branchname` to the end of the download name, eg `TheBloke/stablelm-zephyr-3b-GPTQ:gptq-4bit-32g-actorder_True`
|
138 |
+
|
139 |
+
### From the command line
|
140 |
+
|
141 |
+
I recommend using the `huggingface-hub` Python library:
|
142 |
+
|
143 |
+
```shell
|
144 |
+
pip3 install huggingface-hub
|
145 |
+
```
|
146 |
+
|
147 |
+
To download the `main` branch to a folder called `stablelm-zephyr-3b-GPTQ`:
|
148 |
+
|
149 |
+
```shell
|
150 |
+
mkdir stablelm-zephyr-3b-GPTQ
|
151 |
+
huggingface-cli download TheBloke/stablelm-zephyr-3b-GPTQ --local-dir stablelm-zephyr-3b-GPTQ --local-dir-use-symlinks False
|
152 |
+
```
|
153 |
+
|
154 |
+
To download from a different branch, add the `--revision` parameter:
|
155 |
+
|
156 |
+
```shell
|
157 |
+
mkdir stablelm-zephyr-3b-GPTQ
|
158 |
+
huggingface-cli download TheBloke/stablelm-zephyr-3b-GPTQ --revision gptq-4bit-32g-actorder_True --local-dir stablelm-zephyr-3b-GPTQ --local-dir-use-symlinks False
|
159 |
+
```
|
160 |
+
|
161 |
+
<details>
|
162 |
+
<summary>More advanced huggingface-cli download usage</summary>
|
163 |
+
|
164 |
+
If you remove the `--local-dir-use-symlinks False` parameter, the files will instead be stored in the central Hugging Face cache directory (default location on Linux is: `~/.cache/huggingface`), and symlinks will be added to the specified `--local-dir`, pointing to their real location in the cache. This allows for interrupted downloads to be resumed, and allows you to quickly clone the repo to multiple places on disk without triggering a download again. The downside, and the reason why I don't list that as the default option, is that the files are then hidden away in a cache folder and it's harder to know where your disk space is being used, and to clear it up if/when you want to remove a download model.
|
165 |
+
|
166 |
+
The cache location can be changed with the `HF_HOME` environment variable, and/or the `--cache-dir` parameter to `huggingface-cli`.
|
167 |
+
|
168 |
+
For more documentation on downloading with `huggingface-cli`, please see: [HF -> Hub Python Library -> Download files -> Download from the CLI](https://huggingface.co/docs/huggingface_hub/guides/download#download-from-the-cli).
|
169 |
+
|
170 |
+
To accelerate downloads on fast connections (1Gbit/s or higher), install `hf_transfer`:
|
171 |
+
|
172 |
+
```shell
|
173 |
+
pip3 install hf_transfer
|
174 |
+
```
|
175 |
+
|
176 |
+
And set environment variable `HF_HUB_ENABLE_HF_TRANSFER` to `1`:
|
177 |
+
|
178 |
+
```shell
|
179 |
+
mkdir stablelm-zephyr-3b-GPTQ
|
180 |
+
HF_HUB_ENABLE_HF_TRANSFER=1 huggingface-cli download TheBloke/stablelm-zephyr-3b-GPTQ --local-dir stablelm-zephyr-3b-GPTQ --local-dir-use-symlinks False
|
181 |
+
```
|
182 |
+
|
183 |
+
Windows Command Line users: You can set the environment variable by running `set HF_HUB_ENABLE_HF_TRANSFER=1` before the download command.
|
184 |
+
</details>
|
185 |
+
|
186 |
+
### With `git` (**not** recommended)
|
187 |
+
|
188 |
+
To clone a specific branch with `git`, use a command like this:
|
189 |
+
|
190 |
+
```shell
|
191 |
+
git clone --single-branch --branch gptq-4bit-32g-actorder_True https://huggingface.co/TheBloke/stablelm-zephyr-3b-GPTQ
|
192 |
+
```
|
193 |
+
|
194 |
+
Note that using Git with HF repos is strongly discouraged. It will be much slower than using `huggingface-hub`, and will use twice as much disk space as it has to store the model files twice (it stores every byte both in the intended target folder, and again in the `.git` folder as a blob.)

## How to easily download and use this model in [text-generation-webui](https://github.com/oobabooga/text-generation-webui)
|
199 |
+
|
200 |
+
Please make sure you're using the latest version of [text-generation-webui](https://github.com/oobabooga/text-generation-webui).
|
201 |
+
|
202 |
+
It is strongly recommended to use the text-generation-webui one-click-installers unless you're sure you know how to make a manual install.
|
203 |
+
|
204 |
+
1. Click the **Model tab**.
|
205 |
+
2. Under **Download custom model or LoRA**, enter `TheBloke/stablelm-zephyr-3b-GPTQ`.
|
206 |
+
|
207 |
+
- To download from a specific branch, enter for example `TheBloke/stablelm-zephyr-3b-GPTQ:gptq-4bit-32g-actorder_True`
|
208 |
+
- see Provided Files above for the list of branches for each option.
|
209 |
+
|
210 |
+
3. Click **Download**.
|
211 |
+
4. The model will start downloading. Once it's finished it will say "Done".
|
212 |
+
5. In the top left, click the refresh icon next to **Model**.
|
213 |
+
6. In the **Model** dropdown, choose the model you just downloaded: `stablelm-zephyr-3b-GPTQ`
|
214 |
+
7. The model will automatically load, and is now ready for use!
|
215 |
+
8. If you want any custom settings, set them and then click **Save settings for this model** followed by **Reload the Model** in the top right.
|
216 |
+
|
217 |
+
- Note that you do not need to and should not set manual GPTQ parameters any more. These are set automatically from the file `quantize_config.json`.
|
218 |
+
|
219 |
+
9. Once you're ready, click the **Text Generation** tab and enter a prompt to get started!

## Serving this model from Text Generation Inference (TGI)
|
225 |
+
|
226 |
+
It's recommended to use TGI version 1.1.0 or later. The official Docker container is: `ghcr.io/huggingface/text-generation-inference:1.1.0`
|
227 |
+
|
228 |
+
Example Docker parameters:
|
229 |
+
|
230 |
+
```shell
|
231 |
+
--model-id TheBloke/stablelm-zephyr-3b-GPTQ --port 3000 --quantize gptq --max-input-length 3696 --max-total-tokens 4096 --max-batch-prefill-tokens 4096
|
232 |
+
```
|
233 |
+
|
234 |
+
Example Python code for interfacing with TGI (requires huggingface-hub 0.17.0 or later):
|
235 |
+
|
236 |
+
```shell
|
237 |
+
pip3 install huggingface-hub
|
238 |
+
```
|
239 |
+
|
240 |
+
```python
|
241 |
+
from huggingface_hub import InferenceClient
|
242 |
+
|
243 |
+
endpoint_url = "https://your-endpoint-url-here"
|
244 |
+
|
245 |
+
prompt = "Tell me about AI"

'''
|
250 |
+
|
251 |
+
client = InferenceClient(endpoint_url)
|
252 |
+
response = client.text_generation(prompt,
|
253 |
+
max_new_tokens=128,
|
254 |

## Python code example: inference from this GPTQ model
|
265 |
+
|
266 |
+
### Install the necessary packages
|
267 |
+
|
268 |
+
Requires: Transformers 4.33.0 or later, Optimum 1.12.0 or later, and AutoGPTQ 0.4.2 or later.
|
269 |
+
|
270 |
+
```shell
|
271 |
+
pip3 install --upgrade transformers optimum
|
272 |
+
# If using PyTorch 2.1 + CUDA 12.x:
|
273 |
+
pip3 install --upgrade auto-gptq
|
274 |
+
# or, if using PyTorch 2.1 + CUDA 11.x:
|
275 |
+
pip3 install --upgrade auto-gptq --extra-index-url https://huggingface.github.io/autogptq-index/whl/cu118/
|
276 |
+
```
|
277 |
+
|
278 |
+
If you are using PyTorch 2.0, you will need to install AutoGPTQ from source. Likewise if you have problems with the pre-built wheels, you should try building from source:
|
279 |
+
|
280 |
+
```shell
|
281 |
+
pip3 uninstall -y auto-gptq
|
282 |
+
git clone https://github.com/PanQiWei/AutoGPTQ
|
283 |
+
cd AutoGPTQ
|
284 |
+
git checkout v0.5.1
|
285 |
+
pip3 install .
|
286 |
+
```
|
287 |
+
|
288 |
+
### Example Python code

## Model Description
|
383 |
+
|
384 |
+
`StableLM Zephyr 3B` is a 3 billion parameter instruction tuned inspired by [HugginFaceH4's Zephyr 7B](https://huggingface.co/HuggingFaceH4/zephyr-7b-beta) training pipeline this model was trained on a mix of publicly available datasets, synthetic datasets using [Direct Preference Optimization (DPO)](https://arxiv.org/abs/2305.18290), evaluation for this model based on
|
385 |
+
[MT Bench](https://tatsu-lab.github.io/alpaca_eval/) and [Alpaca Benchmark](https://tatsu-lab.github.io/alpaca_eval/)
|
386 |
+
|
387 |
+
## Usage
|
388 |
+
|
389 |
+
`StableLM Zephyr 3B` uses the following instruction format:
|
390 |
+
```
|
391 |
+
<|user|>
|
392 |
+
List 3 synonyms for the word "tiny"<|endoftext|>
|
393 |
+
<|assistant|>
|
394 |
+
1. Dwarf
|
395 |
+
2. Little
|
396 |
+
3. Petite<|endoftext|>
|
397 |
+
```
|
398 |
+
|
399 |
+
This format is also available through the tokenizer's `apply_chat_template` method:
|
400 |
+
|
401 |
+
```python
|
402 |
+
from transformers import AutoModelForCausalLM, AutoTokenizer
|
403 |
+
|
404 |
+
tokenizer = AutoTokenizer.from_pretrained('stabilityai/stablelm-zephyr-3b')
|
405 |
+
model = AutoModelForCausalLM.from_pretrained(
|
406 |
+
'stabilityai/stablelm-zephyr-3b',
|
407 |
+
trust_remote_code=True,
|
408 |
+
device_map="auto"
|
409 |
+
)
|
410 |
+
|
411 |
+
prompt = [{'role': 'user', 'content': 'List 3 synonyms for the word "tiny"'}]
|
412 |
+
inputs = tokenizer.apply_chat_template(
|
413 |
+
prompt,
|
414 |
+
add_generation_prompt=True,
|
415 |
+
return_tensors='pt'
|
416 |
+
)
|
417 |
+
|
418 |
+
tokens = model.generate(
|
419 |
+
inputs.to(model.device),
|
420 |
+
max_new_tokens=1024,
|
421 |
+
temperature=0.8,
|
422 |
+
do_sample=True
|
423 |
+
)
|
424 |
+
|
425 |
+
print(tokenizer.decode(tokens[0], skip_special_tokens=False))
|
426 |
+
```

### Training Infrastructure
|
492 |
+
|
493 |
+
* **Hardware**: `StableLM Zephyr 3B` was trained on the Stability AI cluster across 8 nodes with 8 A100 80GBs GPUs for each nodes.
|
494 |
+
* **Code Base**: We use our internal script for SFT steps and used [HuggingFace Alignment Handbook script](https://github.com/huggingface/alignment-handbook) for DPO training.
|
495 |
+
|
496 |
+
## Commitment to Ethical AI
|
497 |
+
In line with our responsibility towards ethical AI development, `StableLM Zephyr 3B` is released with a focus on ensuring safety, reliability, and appropriateness in its applications. To this end, we have evaluated `StableLM Zephyr 3B` on 488 malicious prompts and used standard protocols to assess the harmfulness of its outputs. Compared to Zephyr-7b-β, `StableLM Zephyr 3B` reduces the number of harmful outputs as assessed by GPT-4 by 55. Additionally, we performed an internal red teaming event targeting the following abuse areas:
|
498 |
+
* **Self-Harm Methods**: (Suicide Methods, Encouragement of Self-Harm, Methods and encouragement of Eating Disorders)
|
499 |
+
* **Misinformation**: (Health, Conspiracy Theories, Social Unrest/Conflict, Political Misinformation, & Climate change)
|
500 |
+
* **Hate Speech**: (Race, Stereotypes, Immigrants, Gender, Personally Identifiable Information such as Social security numbers, Full names, ID numbers, Email addresses, and telephone numbers)
|
501 |
+
|
502 |
+
We have incorporated the findings of our malicious prompts evaluation and red teaming event into our release. Users are encouraged to fine-tune and evaluate the model to suit their specific needs, considering the potential biases and limitations found in `StableLM Zephyr 3B` and inherent in other LLM models.
|
503 |
+
|
504 |
+
## Use and Limitations
|
505 |
+
|
506 |
+
### Intended Use
|
507 |
+
|
508 |
+
The model is intended to be used as a foundational base model for application-specific fine-tuning. Developers must evaluate and fine-tune the model for safe performance in downstream applications.
|
509 |
+
|
510 |
+
### Limitations and Bias
|
511 |
+
|
512 |
+
This model is not trained against adversarial inputs. We strongly recommend pairing this model with an input and output classifier to prevent harmful responses.
|
513 |
+
|
514 |
+
Through our internal red teaming, we discovered that while the model will not output harmful information if not prompted to do so, it is willing to output potentially harmful outputs or misinformation when the user requests it. Using this model will require guardrails around your inputs and outputs to ensure that any outputs returned are not misinformation or harmful. Additionally, as each use case is unique, we recommend running your own suite of tests to ensure proper performance of this model. Finally, do not use the models if they are unsuitable for your application, or for any applications that may cause deliberate or unintentional harm to others.

|
36 |
+
num_hidden_layers (`int`, *optional*, defaults to 32):
|
37 |
+
Number of hidden layers in the Transformer decoder.
|
38 |
+
num_attention_heads (`int`, *optional*, defaults to 32):

41 |
+
This is the number of key_value heads that should be used to implement Grouped Query Attention. If

`num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
|
44 |
+
converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
|
45 |
+
by meanpooling all the original heads within that group. For more details checkout [this
|
46 |
+
paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
|
47 |
+
`num_attention_heads`.
|
48 |
+
hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
|
49 |
+

|
57 |
+
initializer_range (`float`, *optional*, defaults to 1e-5):
|
58 |
+
The standard deviation of the truncated_normal_initializer for initializing
