rnnandi/bangla-smollm-135m 🇧🇩

Model Description

The rnnandi/bangla-smollm-135m is a highly efficient, compact Language Model (LLM) consisting of 135 million parameters, specifically adapted for the Bangla (Bengali) language. It is designed for maximal efficiency, making it suitable for low-latency inference on edge devices, mobile applications, and resource-constrained environments.

The model's evaluation focuses on its ability to handle core Bengali language understanding and reasoning tasks, offering a strong balance between size and performance for the low-resource language domain.

Intended Use

This model is primarily intended for:

1. Low-Resource Deployment: Applications requiring fast inference and a minimal memory footprint on mobile, edge, or IoT devices.
2. Bangla Text Generation: Generating coherent and contextually relevant text in the Bengali language.
3. Base Model for Transfer Learning: A highly efficient and cost-effective base for fine-tuning on specific, high-value Bengali downstream tasks.

How to Use

The model can be loaded directly from the Hugging Face Hub using the transformers library.

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "rnnandi/bangla-smollm-135m" 

tokenizer = AutoTokenizer.from_pretrained(model_id)
# Use the appropriate data type for your deployment environment (e.g., torch.float16 or torch.bfloat16)
model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.bfloat16) 

# Example: Simple Text Generation Prompt
prompt = "বাংলাদেশ প্রাকৃতিকভাবে সুন্দর" 

inputs = tokenizer(prompt, return_tensors="pt")

# Optional: Move to GPU for faster inference
if torch.cuda.is_available():
    model.to('cuda')
    inputs = {k: v.to('cuda') for k, v in inputs.items()}

outputs = model.generate(
    **inputs, 
    max_new_tokens=64, 
    do_sample=True, 
    temperature=0.7, 
    top_p=0.9,
    eos_token_id=tokenizer.eos_token_id
)

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