Join us for the fastest hackathon ever in Berlin – build and ship a real app in just a few hours.
We'll kick off with a 15 minute session from an OpenAI engineer on how to use Codex to ship apps fast, followed by a short input on agent tracing and evaluation from Langfuse.
Then it's time to build. Bring your laptop and an idea – or pick one up on the spot. Engineers from OpenAI and Langfuse will be around to help. At the end, submit a short demo video of what you've built.
What's included:
$50 API credits per team (sponsored by OpenAI)Food & drinksPrizes for the best projectsOpenAI & Langfuse Swag
Who should apply: Engineers only – this is a hands-on building event.
Space is limited to 30 people. Applications will be reviewed.
