Collaborative Agent Hackathon - Berlin, Germany, 2026

It is great to have you taking part in our Collaborative Agent Hackathon in Cambridge! As participants, you will be among the first to get limited access to Flower Agent and explore what becomes possible when collaborative AI runs on SuperGrid.

This post is the main reference point for the day, with information about the schedule, tracks, technical resources, demos, and support.

You do not need to arrive with a team or a finished idea. We will help you form teams, choose a direction and turn your ideas into working projects during the day.

At a glance

  • Date: Wednesday 16 September
  • Time: 9:30 am to 7:00 pm
  • Venue: Impact Hub Berlin

Registration and a light breakfast start at 9:30 am. Lunch, refreshments and snacks will be provided. Project demos begin at 5:30 pm, and prizes will be awarded at 6:45 pm.

Before you arrive

To help you get started quickly on the day, please complete the following:

  • Create or verify your Flower Account. If you do not already have one, please create your Flower Account. Please have the email address registered to your account ready on the day.
  • Install a Python package and project manager. We recommend uv. If you already use another Python package or project manager, you can use that instead.
  • Read the Flower Agent documentation. You do not need to build a complete project in advance, but the tutorials will help you get started quickly. (Refer to the Warmup section below)
  • Join the Flower Slack workspace. Join the workspace at flower.ai/join-slack, then join #hackathon_berlin_2026. We will use this channel for announcements, support and questions.
  • Bring your laptop and cables. Bring your laptop, charger and any cables or adapters you need. Extension cords will be provided, but supplies may be limited, so please bring a suitable extension lead or power strip if you have one.

To use Flower Agent on SuperGrid, we will help with access and allow-listing at the start of the day. Your registered Flower Account email will help us get you set up quickly.

Warmup

Please spend some time familiarising yourself with the Flower Agent workflow before you arrive. These resources will help you get started quickly:

You do not need to complete every tutorial. A quick look at the relevant sections will make it easier to choose a direction and start building on the day :rocket:.

The challenge

Flower Agent Harness

Showcase the collaborative aspect of Flower Agents running on SuperGrid. Agents can significantly accelerate our work, how would collaborative agents multiply that? Using the existing SuperGrid infrastructure, your goal is to showcase the collaborative aspect of Flower Agents running on SuperGrid. You might build an agent chain in which multiple agents contribute to a result, or use multiple AgentApps that share context and hand work between agents. Bonus point if you use our recently released Endeavor model.

Support during the day

Mentors will be available throughout the day to help with setup, ideas and technical questions. You can also ask questions in #hackathon_berlin_2026 or speak to any member of the Flower Labs team.

Submission and demos

Before the demos, each team will submit:

  • Team details (team name, members, and email addresses)
  • Selected track
  • Short project description
  • Published Flower Hub app
  • GitHub repository link

Each team will have 3–5 minutes to show what they built, followed by questions from the judges. Keep the demo focused on the problem, the working result and how Flower Agent helps your solution.

Prize evaluation criteria

Agent performance may inform the assessment, but it is not the sole or decisive factor. Projects will be assessed on the primary theme of collaborative agents, on these dimensions:

  1. Impact - The value and usefulness of the solution.
  2. Innovation - The originality of the approach.
  3. Use of Flower - How effectively the project uses Flower Agent and SuperGrid.
  4. Technical execution - Whether the project works and is well built.
  5. Demo and delivery - How clearly and effectively the project is presented.
  6. Safety and oversight - Whether the project is transparent, reliable and appropriately supervised.

Prizes

Prizes will be awarded to the top three projects at the end of the day.

​:1st_place_medal: 1st place — AirPods Pro 3 for each team member

​:2nd_place_medal: 2nd place — Sonos Roam 2 for each team member

​:3rd_place_medal: 3rd place — AeroPress Sets for each team member

We are excited to seeing what you build! Come ready to experiment, learn from one another, and explore what collaborative agents can do with Flower.

See you in Berlin!

The Flower team

FAQ

How many people should be on a team?

We recommend teams of 2–4 people, ideally with complementary interests and experience. You can work on your own, but in the spirit of collaboration, we encourage you to build projects together and combine your different skills.

Can I ask questions to the Flower team?

Yes! We are more than happy to answer any questions you may have. Just walk up to any Flower team member and ask directly.

Is there a credit limit to running agents on SuperGrid?

Yes there is a limit. We will ensure that you have sufficient credits to run your AgentApps on SuperGrid throughout the duration of the hackathon. Speak to any member of the Flower Labs team if you think you will need more to complete your project on the day.

Is there a time limit for running AgentApps on SuperGrid?

Yes. Each task has a 5-minute timeout, starting from when the task switches to the Running status.

I've some feedback! Where or who can I share it with?

That’s awesome and thank you for that! We welcome any feedback to improve the overall Flower Agent experience. You can drop your feedback by clicking on the “Share feedback” icon on SuperGrid. Alternatively, you can share it in the #hackathon_berlin_2026 channel or speak directly with one of the Flower Labs team.
