  # Bengali GPT-2
  
  Bengali GPT-2 demo. Part of the [Huggingface JAX/Flax event](https://discuss.huggingface.co/t/open-to-the-community-community-week-using-jax-flax-for-nlp-cv/). Also features a [finetuned](https://huggingface.co/khalidsaifullaah/bengali-lyricist-gpt2?) model on bengali song lyrics. 
  
  # Model Description
  
  OpenAI GPT-2 model was proposed in [Language Models are Unsupervised Multitask Learners](https://paperswithcode.com/paper/language-models-are-unsupervised-multitask) paper .Original GPT2 model was a causal (unidirectional) transformer pretrained using language modeling on a very large corpus of ~40 GB of text data. This model has same configuration but has been pretrained on bengali corpus of mC4(multilingual C4) dataset. The code for training the model has all been open-sourced [here](https://huggingface.co/flax-community/gpt2-bengali/tree/main).
  
  # Training Details
  
  Overall Result: 
  
  ```Eval loss : 1.45, Eval Perplexity : 3.141```
  
  Data: [mC4-bn](https://huggingface.co/datasets/mc4)
  
  Train Steps: 250k steps

  # Usage 
  
  For using the model there are multiple options available. For example using the pipeline directly we can try to generate sentences.
  
  ```
  from transformers import pipeline
  
  gpt2_bengali = pipeline('text-generation',model="flax-community/gpt2-bengali", tokenizer='flax-community/gpt2-bengali')
  ```
  
  Similarly for using the finetuned model on bangla songs we can use following.
  
  ```
  from transformers import pipeline
  
  singer = pipeline('text-generation',model="khalidsaifullaah/bengali-lyricist-gpt2", tokenizer='khalidsaifullaah/bengali-lyricist-gpt2')
  ```
  
  For using on other tasks the model needs to be fine-tuned on custom datasets. Details can be found in huggingface [documentation](https://huggingface.co/transformers/training.html)
