​A gathering for developers building with agents, open models, and physical AI.

​Join NVIDIA and Berlin’s AI builder community for an afternoon of live demos, technical talks, an agent challenge, and conversations with developers building the next generation of AI in Europe. Whether you’re developing an AI-native product, adapting open models, or exploring how agentic and physical AI move from prototype to production, come see what others are building—and meet the people behind the work.

​This is a community event for builders at every level. Whether you’re just discovering what agents can do or already running them in production, there’s something here for you.

​This is a standalone community event. No GTC pass is required.

• ​📍 Berlin (address shared upon registration)

• ​🗓 Saturday, October 17, 2026 from 4–8 p.m.

• ​🎟 Free! Registration is required due to limited capacity.

• ​✅ Registration confirmation with QR code required for entry.

​What to Expect

​🤖 Hands-on demos: Get hands-on with autonomous agents, physical AI, and open models running on NVIDIA hardware including DGX Spark, DGX Station, and more. See the full spectrum from personal to enterprise scale.

​🏆 Live Agent Gauntlet: A head-to-head developer competition where participants deploy pre-built autonomous agents to solve dynamic unknown puzzles. Once connected to a black box server, agents must independently discover hidden tools and tackle multimodal challenges spanning text, image, audio, and video.

​🌍 Built in Europe: Meet European startups, model builders, and developer teams presenting the products and experiments they’re building.

​🎤 Technical talks and conversations: Hear opening remarks from Thomas Jarzombek, State Secretary at Germany’s Federal Ministry for Digital and Public Sector Modernisation, followed by NVIDIA’s Kari Briski. Then join Merantix Momentum, Wandelbots, and Prior Labs for a panel on what it takes to build Germany’s next AI champions.

​🆓 Free compute access: Every attendee leaves with Brev credits and endpoint access to keep building after tonight.

​🎁 Raffle Giveaway: Attendees have a chance to win an NVIDIA DGX Spark (Founders Edition) or a ASUS ProArt P16 NVIDIA RTX Spark Laptop.

​🍻 From agents to ale: Stick around for the OpenClaw Brewery story with Gerhard Erschwendner of Lobster Lager, followed by the raffle and Agent Challenge winners. Enjoy food, drinks, and plenty of time to meet fellow builders—all on us.

​Who This Is For

• ​Developers and engineers curious about agents, open models, and physical AI

• ​Students and researchers who want to see what becomes possible with real hardware access

• ​Startup founders evaluating the agentic stack

• ​Open source contributors and community builders

• ​Anyone not going to GTC Berlin who still wants to be part of the moment

​Why Come

​NVIDIA is bringing together builders, model makers, and researchers for one afternoon before GTC Berlin opens. See Nemotron, Cosmos, and the broader open model ecosystem in action. Meet the people building with it. Find your next collaborator, teammate, or idea, and leave with free compute to keep going.

​‼️ Note: Registration is first come first served. Entry may be limited based on capacity on the day.
