AI Engineer World's Fair Hackathon 2026

Welcome to the second official AI Engineer World’s Fair Hackathon, hosted with Cerebral Valley.

The world is progressing towards recursive self-improvement (RSI), but what happens when AI is capable of building itself?

This hackathon is dedicated to exploring that future. Come build at the edge of RSI: systems that learn from their own outputs and AI that becomes more capable through continuous iteration.

Winners will receive $35,000+ across cash prizes and partner credits.
