Ragnarok
Organized by CRISPR
RAGNAROK is the flagship agentic hackathon of TantraFiesta 2026, organized by AIRA, the AI/ML domain at CRISPR, IIIT Nagpur. The age of passive AI is ending: the next wave of software is built from agents that reason, plan, use tools, and act on their own. RAGNAROK brings together the sharpest student builders in India to design, ship, and battle-test such systems under real pressure. Qualify online, then reach the IIIT Nagpur campus for a 24-hour build where only the best agents survive.
