AI Engineer World's Fair Hackathon 2026
San Francisco, CAJun 27 at 9:00 AM – Jun 28 at 5:00 PM (PDT)
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.
