Daily Recap of IJCAI-ECAI 2026 and the Summer of AI in Bremen

Highlights of the day included keynote speeches by Prof. Dr. Barbara Plank and Prof. David C. Parkes, a discussion on the practical implementation of the EU AI Act, Industry Day, Guided Tours of the exhibition, and the AI Lounge, which focused on AI in public administration.

A central scientific highlight was Barbara Plank’s keynote, “The Myth of Ground Truth: What Human Disagreement Teaches Us About AI.” She challenged the assumption that AI systems should always be trained toward one single correct answer. Instead, she argued that human disagreement can provide valuable information about ambiguity, context and social reality. Her message: variation in human judgment is often not noise to be eliminated, but signal to be understood.

David C. Parkes from Harvard University, recipient of the 2026 IJCAI John McCarthy Award, continued the day’s focus on the future of AI. In his invited talk, “From Intelligent Agents to Agent Societies,” he asked what comes next if generally intelligent agents can be built. His answer focused on multi-agent AI: systems that interact, negotiate, share resources and align incentives. Using Bremen culinary specialties as examples, he brought concepts from combinatorial auctions to life and showed that the rules and structures governing agent societies are just as important as the systems themselves.

EU AI ACT: From legislation to practical implementation

Responsible AI governance was another key topic. In an invited session on the EU AI Act, Jeroen Delfos from the European Commission highlighted the shift from legislation to practical implementation. The discussion focused on technical standards, practical compliance, support for universities and SMEs, human oversight, AI-generated content and the contribution researchers can make to standardisation work, codes of practice and stakeholder consultations.

Where Research Meets Application: IJCAI-ECAI 2026 Industry Day

The IJCAI-ECAI 2026 Industry Day delivered a dynamic showcase of cutting-edge applications, sovereign technology infrastructure, and collaborative innovation, bringing together global tech leaders and the local startup ecosystem.

The morning sessions opened with insights into high-scale real-time translation from DeepL, where speakers Leonie Neuhäußer and Kristina Geißler demonstrated advanced voice and document translation capabilities designed to dismantle global communication barriers. Conference attendees are invited to the DeepL booth to take on the speed challenge: see how your pace stacks up against Claude.

T-Systems followed, with Björn Weidenmüller presenting Europe’s first Industrial AI Cloud launched in February 2026 by T-Systems International in partnership with Deutsche Telekom and NVIDIA. Concluding the morning corporate spotlights, Mulang Onando from SAP detailed how combining Business Knowledge Graphs with agentic systems and semantically linked tabular data enables enterprise AI to understand context and execute complex reasoning within systems like SAP Joule.

In the afternoon, the focus turned toward applied engineering and the growth of the local ecosystem. Joint perspectives were delivered by Udo Gödel of CONTACT Software and Jörn Syrbe of team neusta, setting the stage for an engaging session hosted by the State of Bremen. Moderated by Mareike Mgwelo of Starthaus Bremen & Bremerhaven, the interactive startup feature brought together local founders Rafael Reisenhofer of Count from Above, Chris Robin Wübbeler of ellamind, and Dr. Christian Geier of prokube. Rather than standard pitches, the founders presented active business and technical challenges directly to the IJCAI community. This format invited researchers and industry experts to collaborate in real time, bridging academic expertise with startup agility to elaborate on real-world industry problems.

Guided Tours for company representatives

Four guided tours at the IJCAI-ECAI 2026 Exhibition offered company representatives and entrepreneurs a curated look at how artificial intelligence is being developed and applied across robotics, language, health, and digital business processes.

Starting from the Bremen stand, the groups visited selected company and research booths for short expert talks, demonstrations, and discussions tailored to each tour topic. The stops brought together perspectives from international research and industry and showed how AI is already being applied across a wide range of fields.

The AI x Robotics tour was led by Dr. Nina Hoyer (University of Bremen / DFKI), AI x Language by Katalina Kopka (University of Bremen), AI x Health by Lena Wollschläger (U Bremen Research Alliance), and AI x Digital Business Processes by Derk H. Schönfeld (U Bremen Research Alliance).

Across all four tours, the shared focus was on making current AI developments tangible, connecting research with real-world applications, and creating opportunities for direct exchange with experts at the exhibition.

AI Meets Soccer: Banquet at Weserstadion

The day wrapped up with a special highlight: the official IJCAI-ECAI 2026 banquet at Bremen’s Weserstadion, home of Bundesliga club Werder Bremen. Located directly on the Weser River, the stadium usually holds up to 42,100 spectators. On Wednesday evening, it became the setting for an atmospheric conference gathering.

In the VIP areas North and East, attendees enjoyed the opportunity to meet, exchange ideas, and sample a variety of culinary offerings. The stands and stadium interior were also open, illuminated in green and white and offering space to linger in mild evening temperatures.

A further highlight was the demonstration by B-Human, the robot soccer team jointly developed by the University of Bremen and DFKI. With 13 RoboCup World Championship titles and numerous German championships to its name, B-Human brought artificial intelligence and soccer together in a setting closely associated with Bremen.

Sincere thanks go to Local Social Chairs Katalina Kopka, University of Bremen, and Klaus Eickel, Fraunhofer MEVIS and Bremerhaven University of Applied Sciences, for organizing an extraordinary evening.

AI Lounge: AI x Administration

As a public outreach event and part of the Summer of AI in Bremen (https://www.bremen-innovativ.de/en/summer-of-ai/), Wednesdays AI Lounge on Domshof brought the discussion around artificial intelligence directly into the city.

Dustin Klepper (neuraflow GmbH), Dr. Christina Gloerfeld (University of Bremen), and Prof. Dennis-Kenji Kipker (Bremen University of Applied Sciences) discussed how AI can support the digital transformation of public administration, from more efficient processes and better services to the legal, technical, and organisational requirements for responsible use.

Organized by Dr.-Ing. Thomas Eßmeyer from the University of Bremen, the German-language event created an open forum for exchange between experts and the public on the opportunities and challenges of AI in public institutions.

Wednesday showed what IJCAI-ECAI 2026 in Bremen stands for: international scientific excellence, responsible innovation and open exchange between research, industry, policy and society.
