The one theme
AI for Bharat, wherever it’s needed.
AI can now understand a question in Hindi and answer it in seconds, from a pension form for a jawan’s mother back home to first aid at a border post. At GBH you build AI that solves real problems for India, with any model or API: in the cloud, or on the device so it works even with no network.
Where AI can help
- Governance
- Security
- Education
- Logistics
- Public service
बड़े मॉडल दूर सर्वर पर चलते हैं और नेटवर्क से पल भर में जवाब भेजते हैं।
नेटवर्क हो, तो सबसे बड़े मॉडल भी हाथ में।

जवान साथी
ऑन-डिवाइस मॉडल
नेटवर्क नहीं। फिर भी जवाब।
साथी को साँप ने काटा है। अभी क्या करूँ?
घबराएँ नहीं, उन्हें शांत और स्थिर रखें। अँगूठी या कसी चीज़ें हटा दें। चीरा न लगाएँ, ज़हर न चूसें। तुरंत मेडिकल पोस्ट ले जाएँ।
फ़ोन पर ही प्रोसेस हुआ
बिना नेटवर्क के भी। धन्यवाद!
कुछ भी पूछें, ऑफ़लाइन
मॉडल फ़ोन पर ही चलता है, इसलिए नेटवर्क न हो तब भी जवाब मिलता है।
In every language
AI can listen, read and answer in the languages people speak.
Even offline
One option: a model on the phone keeps working with no network.
Any AI
Gemini, OpenAI, open models or on-device: pick what fits.

Who can take part?
Developers currently enrolled (UG, PG or diploma) at any college or university in India, in teams of 2 to 4. Registration is free and open Pan-India.

What will we build with?

When are the problem statements revealed?
All four, including the dedicated BSF track, are published on this site together, before ideas close. Until then they stay sealed.
