This model is a fine-tuned version of the meta-llama/Meta-Llama-3.1-8B-Instruct model, specifically tailored for generating and understanding Persian text. The fine-tuning was conducted using the TinyStories-Farsi dataset, which includes a diverse set of short stories in Persian. The primary goal of this fine-tuning was to enhance the model's performance in instruction-following tasks within the Persian language.

Training Details

Training Data

The model was fine-tuned using the TinyStories-Farsi dataset. This dataset provided a rich and diverse linguistic context, helping the model better understand and generate text in Persian.

Training Procedure

The fine-tuning process was conducted using the following setup:

Epochs: 4
Batch Size: 8
Gradient Accumulation Steps: 2
Hardware: NVIDIA A100 GPU

Fine-Tuning Strategy

To make the fine-tuning process efficient and effective, PEFT (Parameter-Efficient Fine-Tuning) techniques were employed. Specifically, the BitsAndBytesConfig(load_in_4bit=True) configuration was used, allowing the model to be fine-tuned in 4-bit precision. This approach significantly reduced the computational resources required while maintaining high performance, resulting in a training time of approximately 2 hours. The use of BitsAndBytesConfig(load_in_4bit=True) helped reduce the environmental impact by minimizing the computational resources required.

Uses

Direct Use

This model is well-suited for generating text in Persian, particularly for instruction-following tasks. It can be used in applications like chatbots, customer support systems, educational tools, and more where accurate and context-aware Persian language generation is needed.

Out-of-Scope Use

The model is not intended for tasks requiring deep reasoning, complex multi-turn conversations, or contexts beyond the immediate prompt. It is also not designed for generating text in languages other than Persian.

How to Get Started with the Model

Here is how you can use this model:

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Specify the combined model
model_name = "AmirMohseni/Llama-3.1-8B-Instruct-Persian-finetuned-sft"

# Load the model and tokenizer
model = AutoModelForCausalLM.from_pretrained(model_name, device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Ensure pad_token is set (if not already set)
if tokenizer.pad_token is None:
    tokenizer.add_special_tokens({'pad_token': tokenizer.eos_token})

# Check if CUDA is available, otherwise use CPU
device = "cuda" if torch.cuda.is_available() else "cpu"
model = model.to(device)

# Example usage
input_text = "چطوری میتونم به اطلاعات درباره ی سهام شرکت های آمریکایی دست پیدا کنم؟"

# Tokenize the input
inputs = tokenizer(input_text, return_tensors="pt", padding=True, truncation=True).to(device)

# Generate text
outputs = model.generate(
    inputs['input_ids'],
    attention_mask=inputs['attention_mask'],
    max_length=512,
    pad_token_id=tokenizer.pad_token_id
)

# Decode and print the output
response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)
