# Model Card for Ganga-1b! 🌊

The base model **``Ganga-1b``** trained on a monolingual **Hindi** language dataset as part of ***Project Unity***. We propose the name *Ganga* 🌊 to honor the longest river flowing through the Hindi-speaking region of India 🇮🇳.

*(The first pre-trained Hindi model by any academic research lab in India 🇮🇳!)**

### Model Description 📚

**Project Unity** is an initiative to address **India's linguistic diversity** and richness by creating a comprehensive resource covering the country's major languages. We strive to achieve state-of-the-art performance in understanding and generating text in **Indian languages**. 
To achieve this, we train models on the 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. 
Significantly, the **Ganga-1B** model outperforms existing open-source models that support **Indian languages**, even at sizes of up to **7 billion parameters**. 



- **Developed by:** [Lingo Research Group at IIT Gandhinagar](https://labs.iitgn.ac.in/lingo/) 
- **Model type:** Autoregressive Language Model
- **Language(s) (NLP):** Bilingual (Primary: *Hindi* [**hi**], Secondary: *English* [**en**])
- **License:** Apache 2.0



## How to Get Started with the Model 👨🏻‍💻

Use the code below to get started with the model.

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

input_text = "BCCI ने टी-20 वर्ल्ड कप के बीच जिम्बाब्वे सीरीज "
input_ids = tokenizer.encode(input_text,
            return_tensors="pt").to("cuda")

outputs = model.generate(input_ids, max_new_tokens=100,
          do_sample=True, top_k=50,
          top_p=0.95, temperature=0.7)

print(tokenizer.decode(outputs[0]))

```
