Scaling Indic Pretraining: 2.8 Trillion Tokens and an Open Data Generation Pipeline

We're excited to introduce Nemotron-pretraining-Indic-v1 approximately 2.8 trillion tokens across 22 Indian languages, releasing soon alongside the open, GPU-accelerated data generation pipeline used to create it.

Key points

  • Authors: AI4Bharat — Mohammed Safi Ur Rahman Khan, Mitesh Khapra, Anoop Kunchukuttan.
  • Developed by NVIDIA with IIT Madras, India's premier engineering institute, and its AI4Bharat lab, this release gives model builders a substantial new resource for Indic pretraining.
  • AI4Bharat, IIT Madras' Indian language research lab, builds open-source datasets and models for Indian languages.
  • Our joint open-source release represents a substantial expansion of the open synthetic Indic training data that will be available to the community.
