GPT-5 Startup Hackathon with @cerebral_valley

We gave startups 24 hours to build with GPT-5. Over 275 builders flew in from around the world to hack with our team and @kevinweil.

👇 Here’s who took home the win of DevDay tickets and over $85,000 in credits- thanks to our judges @Alfred_Lin @saranormous @KanuGulati @LM_Braswell!

[Cerebral Valley @cerebral_valley]

We’ve partnered with @OpenAI to host the official GPT-5 Startup Hackathon.

If you’re a startup (pre-seed, seed, series A), come build with GPT-5.

Learn from the OpenAI team, meet fellow founders, and demo for elite judges @shack15sf.

Win DevDay tickets & $50k OpenAI credits.

The most insane part of this demo is that it was built in 4 hours 🤯
