This hackathon is about building with agent harnesses, hands-on, alongside the people building the tools.
We're teaming up with LangChain Ambassador Zamal Babar and Data Reply to host an evening of talks and hacking in Munich. You'll form small groups, build a deep agent from scratch, and demo it to a panel of judges by the end of the night.
What you'll build
The theme is agent harnesses — the scaffolding that turns a model into a system that can plan, use tools, and recover from its own mistakes. Steffen Hausmann will kick things off with two short talks: one on deep agents, and one on managed deep agents. Then you'll put it into practice.
A few days before the event, we'll send out a prompt so you can come with an idea already in mind. Use the time before the hackathon to think through your approach — you'll want it once the clock starts.
What to bring
Your laptop and a group to hack with (we'll help you form one if you don't have one)
Your own API keys for any models or tools you plan to use
Questions for Steffen, Zamal, and the Data Reply team — they'll be around all night
We'll provide LangSmith credits to every attendee for the event, so you can trace and debug your agent as you build.

3rd place: $1,000 in LangSmith credits

About
Mission Zukunftspraxis live erleben: Eine echte Praxis wird an einem Tag vom Chaos zum System umgebaut – mit laufender Bühnenuhr.
Experience the world's famous Oktoberfest with a fresh perspective! We are not avoiding fun, we want to amplify it. The goal is to connect, celebrate, and showcase that the best part of the Wiesn is not the consumption, but the connections you make. 📅 Date: 3.10.2026 🕙 Time: 10:30 AM 📍 Meeting Point: Bavaria Statue, Theresienhöhe 16, Munich (Exact Spot: https://share.google/UhwYsr7tbGG6PGFqF) 🎟️ Entry: Free to meet up. Everyone pays for their own consumption (we might need to pay the 4€ entrance fee for the Oide Wiesn) By joyfully participating in events like this without alcohol, we help normalize mindful choices and demonstrate that true connection comes from shared experiences, not shared drinks. 🥨 What to Expect 10:30 AM: We'll gather at the iconic Bavaria statue for a meet-and-greet and a fantastic group photo in our traditional outfits (Tracht). Our Plan: The goal is to head to the Oide Wiesn (Old Oktoberfest), a charming, more traditional section of the festival with a relaxed atmosphere. The entry fee is typically €4 and is well worth it for the more manageable crowds. Flexibility is Key: If we spot a great, large-enough space in an outdoor beer garden on our way, we’ll take it! Our priority is finding a place to sit together, talk, and enjoy the morning. The Vibe: Expect relaxed networking, great conversations, and a supportive atmosphere where enjoying an alcohol-free beer is completely normal. 📝 Important Details Finding Us: We will meet directly at the linked spot at the base of the statue. Costs: This is a casual meetup. Please be prepared to pay for your own food, drinks, and the Oide Wiesn entry ticket. Outfits: Wearing Tracht (Dirndl or Lederhosen) is highly encouraged to get into the festive spirit, but it's not required! Good to Know: Yes, every single tent and beer garden on the Wiesn serves excellent alcohol-free beer! Come for the tradition. Stay for the connection.
