**Frequently Asked Questions**
- ***How does the compression work?*** The model is compressed by using bitsandbytes.
- ***How does the model quality change?*** The quality of the model output will slightly degrade.
- ***What is the model format?*** We the standard safetensors format.
- ***How to compress my own models?*** You can request premium access to more compression methods and tech support for your specific use-cases [here](https://z0halsaff74.typeform.com/pruna-access?typeform-source=www.pruna.ai).
## Usage
## Quickstart Guide
Getting started with DBRX models is easy with the `transformers` library. The model requires ~264GB of RAM and the following packages:
```bash
pip install "transformers>=4.39.2" "tiktoken>=0.6.0"
```
If you'd like to speed up download time, you can use the `hf_transfer` package as described by Huggingface [here](https://huggingface.co/docs/huggingface_hub/en/guides/download#faster-downloads).
```bash
pip install hf_transfer
export HF_HUB_ENABLE_HF_TRANSFER=1
```
You will need to request access to this repository to download the model. Once this is granted,
[obtain an access token](https://huggingface.co/docs/hub/en/security-tokens) with `read` permission, and supply the token below.
### Run the model on multiple GPUs:
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
tokenizer = AutoTokenizer.from_pretrained("PrunaAI/dbrx-instruct-bnb-4bit", trust_remote_code=True, token="hf_YOUR_TOKEN")
model = AutoModelForCausalLM.from_pretrained("PrunaAI/dbrx-instruct-bnb-4bit", device_map="auto", torch_dtype=torch.bfloat16, trust_remote_code=True, token="hf_YOUR_TOKEN")
input_text = "What does it take to build a great LLM?"
messages = [{"role": "user", "content": input_text}]
input_ids = tokenizer.apply_chat_template(messages, return_dict=True, tokenize=True, add_generation_prompt=True, return_tensors="pt").to("cuda")
outputs = model.generate(**input_ids, max_new_tokens=200)
print(tokenizer.decode(outputs[0]))
```
## Credits & License
