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.
Ganga-1b is a decoder-only transformer model, featuring the following specifications:
Layers: 16
Attention heads: 32
Embedding dimension: 2,048
Vocabulary size: 30,000
Sliding window: 512
Intermediate dimension: 7,168
