Model Card for Ganga-1b! 🌊

The base model Ganga-1b trained on a monolingual Hindi language dataset as part of Project Unity.
(The first pre-trained Hindi model by any academic research lab in India 🇮🇳!)*

Model Details

Model Description 📚

Project Unity is an initiative aimed at addressing India's linguistic diversity and richness by creating a comprehensive resource that covers the country's major languages. Our goal is to achieve state-of-the-art performance in understanding and generating text in Indian languages. To achieve this, we train models on monolingual regional languages of India. Our first release is the Ganga-1B model, which has been trained on a large dataset of public domain web-crawled hindi language data, including news articles, web documents, books, government publications, educational materials, and social media conversations (filtered for quality). Additionally, the dataset has been further curated by native Indian speakers to ensure high-quality. Importantly, the Ganga-1B model outperforms existing open-source models that support Indian languages, even at sizes of up to 7 billion parameters.

How to Get Started with the Model 👨🏻‍💻

Use the code below to get started with the model.

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline
    
tokenizer = AutoTokenizer.from_pretrained("LingoIITGN/ganga-1b")
model = AutoModelForCausalLM.from_pretrained(
    "LingoIITGN/ganga-1b",
    device_map="auto"
)

pipe = pipeline(task="text-generation", 
                model=model, 
                tokenizer=tokenizer,
                max_new_tokens = 5, 
                temperature = 0.70,
               )
result = pipe(prompt, pad_token_id=pipe.tokenizer.eos_token_id)
print(result)
