**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.

## Usage
```
from transformers import AutoTokenizer
import transformers
import torch
model = "PrunaAI/mattshumer-Hermes-2-Pro-11B-bnb-4bit"
tokenizer = "mattshumer/Hermes-2-Pro-11B"
messages = [{"role": "user", "content": "What is a large language model?"}]
tokenizer = AutoTokenizer.from_pretrained(tokenizer)
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
pipeline = transformers.pipeline(
"text-generation",
model=model,
device_map="auto",
cache_dir='/nfs/students/rachwan/delete_me/hermes'
)
```
outputs = pipeline(prompt, max_new_tokens=256, do_sample=True, temperature=0.7, top_k=50, top_p=0.95)
print(outputs[0]["generated_text"])
