# Welcome to Barka-2b-it : The best 2B Arabic LLM

# Motivation : 

The goal of this project was to adapt large language models for the Arabic language and create a new state-of-the-art Arabic LLM. Due to the scarcity of Arabic instruction fine-tuning data, not many LLMs have been trained specifically in Arabic, which is surprising given the large number of Arabic speakers.  
Our final model was trained on a high-quality instruction fine-tuning (IFT) dataset, generated synthetically and then evaluated using the Hugging Face Arabic leaderboard.

# Training : 
This model is the 2B version. It was trained for 2 days on 1 A100 GPU using LoRA with a rank of 128, a learning rate of 1e-4, and a cosine learning rate schedule.

# Evaluation :
My model is now on the Arabic leaderboard.

# Using the Model

The model uses `transformers` to generate responses based on the provided inputs. Here’s an example code to use the model:

```python
from transformers import AutoTokenizer, AutoModelForCausalLM
from peft import PeftModel
import torch

model_id = "google/gemma-2-2b-it"
peft_model_id = "Slim205/Barka-2b-it"

model = AutoModelForCausalLM.from_pretrained(model_id).to("cuda")
tokenizer = AutoTokenizer.from_pretrained("Slim205/Barka-2b-it")
model1 = PeftModel.from_pretrained(model, peft_model_id)

input_text = "ما هي عاصمة تونس؟"  # "What is the capital of Tunisia?"
chat = [
    { "role": "user", "content": input_text },
]

prompt = tokenizer.apply_chat_template(chat, tokenize=False, add_generation_prompt=True)
inputs = tokenizer.encode(prompt, add_special_tokens=False, return_tensors="pt")
outputs = model.generate(
    input_ids=inputs.to(model.device),
    max_new_tokens=32,
    top_p=0.9,
    do_sample=True
)

print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```
```

ما هي عاصمة تونس؟
model
عاصمة تونس هي تونس. يشار إليها عادة باسم مدينة تونس. المدينة لديها حوالي 2،500،000 نسمة
```
