AI4Bharat and NVIDIA announced the open-source release of Nemotron-pretraining-Indic-v1, a corpus of approximately 2.8 trillion tokens spanning the 22 languages listed in India’s Constitution, representing the first language for 97 % of the population (about 1.2 billion people) Hugging Face Engineering Blog. The dataset is accompanied by a reusable GPU-accelerated pipeline that handles document-level translation, quality assessment, and targeted repair, allowing developers to generate additional synthetic data.
The corpus contains 2,601.0 billion native-script tokens and 224.6 billion romanized tokens, covering twelve languages in both scripts and ten languages in native script only. Workflows employ NeMo Data Designer and Gemma-4-31B-it for translation and scoring, retaining outputs that meet a 75-point quality threshold. The pipeline preserves technical content such as equations, tables, and code, and each synthetic record is traceable to its source document.
Our read: The joint effort supplies a massive, verifiable data source for Indic language models, lowering the barrier for B2B firms to localize AI services across India’s diverse linguistic landscape.
