# QuantFactory/PersianMind-v1.0-GGUF
This is quantized version of [universitytehran/PersianMind-v1.0](https://huggingface.co/universitytehran/PersianMind-v1.0) created using llama.cpp
# Original Model Card
# PersianMind
PersianMind is a cross-lingual Persian-English large language model.
The model achieves state-of-the-art results on Persian subset of the [Belebele](https://github.com/facebookresearch/belebele) benchmark
and the [ParsiNLU multiple-choice QA](https://github.com/persiannlp/parsinlu) task.
It also attains performance comparable to GPT-3.5-turbo in a Persian reading comprehension task.
## Model Description
- **Developed by:** [Pedram Rostami](mailto:pedram.rostami@ut.ac.ir), [Ali Salemi](mailto:alisalemi@ut.ac.ir), and [Mohammad Javad Dousti](mailto:mjdousti@ut.ac.ir)
- **Model type:** Language model

## How to Get Started with the Model
Use the code below to get started with the model.
Note that you need to install sentencepiece and accelerate libraries along with PyTorch and 🤗Transformers to run this code.
```python
from transformers import AutoTokenizer, AutoModelForCausalLM
import torch
device = "cuda" if torch.cuda.is_available() else "cpu"
model = AutoModelForCausalLM.from_pretrained(
"universitytehran/PersianMind-v1.0",
torch_dtype=torch.bfloat16,
low_cpu_mem_usage=True,
device_map={"": device},
)
tokenizer = AutoTokenizer.from_pretrained(
"universitytehran/PersianMind-v1.0",
)
TEMPLATE = "{context}\nYou: {prompt}\nPersianMind: "
CONTEXT = "This is a conversation with PersianMind. It is an artificial intelligence model designed by a team of " \
"NLP experts at the University of Tehran to help you with various tasks such as answering questions, " \
"providing recommendations, and helping with decision making. You can ask it anything you want and " \
"it will do its best to give you accurate and relevant information."
PROMPT = "در مورد هوش مصنوعی ØªÙˆØ¶ÛŒØ Ø¨Ø¯Ù‡."
model_input = TEMPLATE.format(context=CONTEXT, prompt=PROMPT)
input_tokens = tokenizer(model_input, return_tensors="pt")
input_tokens = input_tokens.to(device)
generate_ids = model.generate(**input_tokens, max_new_tokens=512, do_sample=False, repetition_penalty=1.1)
model_output = tokenizer.batch_decode(generate_ids, skip_special_tokens=True, clean_up_tokenization_spaces=False)[0]
print(model_output[len(model_input):])
```
### How to Quantize the Model
Quantized models can be run on resource-constrained devices.
To quantize the model, you should install the bitsandbytes library.
In order to quantize the model in 8-bit (`INT8`), use the code below.
```python
model = AutoModelForCausalLM.from_pretrained(
"universitytehran/PersianMind-v1.0",
device_map="auto",
low_cpu_mem_usage=True,
load_in_8bit=True
)
```
Alternatively, you can quantize the model in 4-bit (`NormalFloat4`) with the following code.
```python
from transformers import BitsAndBytesConfig
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_use_double_quant=True,
bnb_4bit_quant_type="nf4",
)
model = AutoModelForCausalLM.from_pretrained(
"universitytehran/PersianMind-v1.0",
quantization_config=quantization_config,
device_map="auto"
)
```
### Evaluating Quantized Models
| Model | Belebele (Persian) | Fa→En Translation
(Comet) | En→Fa Translation
(Comet) | Model Size | Tokens/sec |
| :----------------------------------------------------------------: | :--------------------------------------------------------------: | :------------------------------------------------------------------------: | :------------------------------------------------------------------------: | :--------: | :--------: |
| PersianMind (`BF16`) | 73.9 | 83.61 | 79.44 | 13.7G | 25.35 |
| PersianMind (`INT8`) | 73.7 | 82.32 | 78.61 | 7.2G | 11.36 |
| PersianMind (`NF4`) | 70.2 | 82.07 | 80.36 | 3.9G | 24.36 |
We evaluated quantized models in various tasks against the original model.
Specifically, we evaluated all models using the reading comprehension multiple-choice
question-answering benchmark of [Belebele](https://github.com/facebookresearch/belebele) (Persian subset) and reported the accuracy of each model.
Additionally, we evaluated our models for Persian-to-English and English-to-Persian translation tasks.
For this, we utilized the Persian-English subset of the [Flores-200](https://github.com/facebookresearch/flores/tree/main/flores200) dataset and
reported our results using the Comet metric.
Furthermore, we calculated the average number of generated tokens per second by each model during running the translation tasks.
To understand resource efficiency, we measured the memory usage of each model by employing the `get_memory_footprint()` function.
