Model: FalconMasr

This model is based on the Falcon-7B model with quantization in 4-bit format for efficient memory usage and fine-tuned using LoRA (Low-Rank Adaptation) for Arabic causal language modeling tasks. The model has been configured to handle causal language modeling tasks specifically designed to improve responses in Arabic.

Model Configuration

• Base Model: ybelkada/falcon-7b-sharded-bf16
• Quantization: 4-bit with nf4 quantization type and float16 computation
• LoRA Configuration: lora_alpha=16, lora_dropout=0, r=64
• Task Type: Causal Language Modeling
• Target Modules: query_key_value, dense, dense_h_to_4h, dense_4h_to_h

Training

The model was fine-tuned on a custom Arabic text dataset, achieving progressive improvements in training loss, as shown in the table below:

Usage

To use this model, load it with the following configuration:

import torch
from transformers import AutoModelForCausalLM,BitsAndBytesConfig
from transformers import AutoTokenizer
import warnings
warnings.filterwarnings("ignore", category=FutureWarning)

# Model Configuration
model_name ="MahmoudIbrahim/FalconMasr"

bnb_config = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_quant_type="nf4",
    bnb_4bit_compute_dtype=torch.float16,
)

# Load model and tokenizer
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    quantization_config=bnb_config,
    trust_remote_code=True,
    low_cpu_mem_usage=True,
)
model.config.use_cache = False


tokenizer =AutoTokenizer.from_pretrained(
    model_name,
    trust_remote_code=True,
)
tokenizer.pad_token = tokenizer.eos_token


input_text = "كيف تختلف منصة المدفوعات المتكاملة لشركة أمريكان إكسبريس عن شبكات البطاقات المصرفية؟"

# Move inputs to the same device as the model
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")

# Set use_reentrant=False for torch checkpointing
torch.utils.checkpoint.checkpoint_sequential.use_reentrant = False

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

# Remove 'token_type_ids' if it's present in the inputs
inputs.pop('token_type_ids', None)

# Generate the output
output = model.generate(**inputs, max_length=200,
                        use_cache=False,pad_token_id=tokenizer.eos_token_id)

# Decode the generated output
decoded_output = tokenizer.decode(output[0], skip_special_tokens=True)
print(decoded_output)
