<span style="font-variant:small-caps;">PersianMind</span>

<span style="font-variant:small-caps;">PersianMind</span> is a cross-lingual Persian-English large language model. The model achieves state-of-the-art results on Persian subset of the <span style="font-variant:small-caps;">Belebele</span> benchmark and the ParsiNLU multiple-choice QA task. It also attains performance comparable to GPT-3.5-turbo in a Persian reading comprehension task.

Model Description

• Developed by: Pedram Rostami, Ali Salemi, and Mohammad Javad Dousti
• Model type: Language model
• Languages: English and Persian

How to Get Started with the Model

Use the code below to get started with the model. Note that you need to install <code><b>sentencepiece</b></code> and <code><b>accelerate</b></code> libraries along with <code><b>PyTorch</b></code> and <code><b>🤗Transformers</b></code> to run this code.

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 توضیح بده."

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 <code><b>bitsandbytes</b></code> library. In order to quantize the model in 8-bit (INT8), use the code below.

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.

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

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 <span style="font-variant:small-caps;">Belebele</span> (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 <span style="font-variant:small-caps;">Flores</span>-200 dataset and reported our results using the <span style="font-variant:small-caps;">Comet</span> 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.
