Langfuse x OpenAI: Fastest Hackathon Ever

Join us for the fastest hackathon ever in Berlin – build and ship a real app in just a few hours.

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.
