Agents are changing what is possible. Their greatest potential emerges when they collaborate safely in human-supervised multi-agent teams.
The Collaborative Agent Hackathon is a one-day event for building open-source, collaborative AI agents using Flower.
Participants will form teams on the day, develop a working prototype and present it at the end of the event. Each team will explore how open-source collaborative agents of varying complexity can work together safely.
You do not need an existing team or a fully developed idea. Bring your laptop, your interests and a willingness to collaborate.
Everyone is welcome, including builders from startups and companies, as well as students, researchers and postdocs from all universities.
Safe collaboration is central to the solution.
Build an open-source agent or multi-agent system using Flower in which the safe collaboration of agent teams is central to the solution.
Projects can range across the full collaborative spectrum. Multiple agents might automate a task, form self-improving loops with one another, or operate across distributed machines and datasets.
Flower is built together with an open-source community spanning more than 7k users world-wide. Flower simplifies building multi-agent systems, supporting distributed coordination, collaborative learning and inference, and privacy-aware deployment.

Welcome
Introduction to the event, the challenge and the day’s practical arrangements.
Collaborative agents with Flower
A technical introduction covering collaborative agent architectures, safe coordination, self-improvement loops and the available Flower resources.
Team formation
Meet potential collaborators and form teams of two to four, unless your team was formed earlier.
Build session
Define the project, design the agent interactions and begin implementation.
Lunch
Build session
Develop and test the system, refine the collaboration or self-improvement loop and prepare the demonstration. Mentors will be available throughout.
Demo preparation
Project demonstrations
Teams present their projects, followed by brief questions.
Dinner, awards and closing remarks
Enjoy dinner as we celebrate the winning projects and bring the hackathon to a close.
Recognising outstanding projects and contributions.
Awards will be presented at the end of the day to recognise outstanding projects and contributions. Further details about prizes and the selection process will be shared before the event.
