Technical Strategy and Model Development
BharatGen follows a phased, modular approach to model development. The process begins with smaller models to refine algorithms, validate data pipelines, and understand the nuances of Indian languages and dialects. Insights from these initial models inform the construction of the trillion-parameter model.
Professor Ganesh Ramakrishnan, principal investigator of BharatGen at IIT Bombay, explained that training such a massive model involves integrating diverse data sources, ranging from government publications and local media to regional radio broadcasts and crowdsourced datasets. OCR tools and annotation platforms are being deployed to digitize and label textual and spoken content efficiently.
This structured approach ensures that the final model is robust, efficient, and capable of handling diverse, multilingual datasets without bias.
Multilingual Capabilities
India’s linguistic diversity is one of the key challenges BharatGen seeks to address. The model is being trained in all 22 scheduled languages, as well as several widely spoken regional dialects. This ensures that the AI can provide accurate outputs for users across the country, regardless of the language they speak.
Multilingual capability is not merely a feature but a design principle. By understanding context, idiomatic expressions, and cultural references in multiple languages, BharatGen aims to deliver highly contextualized and relevant AI responses, setting a new benchmark for regional AI models globally.
Multimodal AI: Beyond Text
BharatGen is also designed to be multimodal, meaning it can process and generate not only text but also voice, audio, and visual data. This capability opens the door for AI-powered applications that are interactive, accessible, and versatile.
For example, a farmer in a remote village could interact with BharatGen via voice commands to receive crop advice, weather updates, or market predictions. Similarly, students can access personalized learning resources in their native languages, while healthcare professionals can obtain decision support through AI-generated summaries of medical literature.
Industry Collaboration and Expertise
To accelerate development and ensure high-quality outputs, BharatGen is collaborating with industry partners, including IBM, which brings expertise in AI architectures, model optimization, and scalable training infrastructures.
