International Summer School on LLM-based Agents for Software Engineering

From September 1 to 3, 2025, i3Lab (Quercus Software Engineering Group and INTIA, University of Extremadura) successfully organized the 1st International Summer School on LLM-Based Agents for Software Engineering (LLMA4SE). The event brought together researchers, professionals and students from academia and industry to explore the rapidly evolving field of LLM-based multi-agent systems and their applications in software engineering.

The opening day featured two keynote talks:

• AgentWare in Software Engineering: A Taxonomy of LLM-Based Multi-Agent Systems, by Davide Di Ruscio, which sparked stimulating discussions.

• Generative AI Models Running in Your Own Infrastructure, delivered by Jesús M. González Barahona, who offered deep insights on openness in AI models.

Participants also enjoyed a hands-on workshop on TDD with the Help of AI, led by Jesús M. González Barahona and Giovanni Rosa. The day concluded with a cultural highlight: a guided tour of the UNESCO World Heritage city of Cáceres.

The second day offered a balanced combination of research and practical applications. The morning began with three particularly interesting presentations:

• Multi-agents for Code Generation, by Jie Zhang, addressing current challenges and approaches.

• AI and Software Development: An Industry Paradigm Shift, by Mario Corchero Jiménez and David Naranjo, who provided an industry perspective.

• From Workflow-based to Fully Agentic Applications: smolagents and LangGraph, by Antonio García Domínguez, who presented various agent development frameworks.

In the afternoon, Antonio García Domínguez guided participants in a highly practical workshop on developing agentic applications with human-in-the-loop using LangGraph. The day also included two enriching social activities: a guided visit to the Helga de Alvear Contemporary Art Museum and a social dinner at the Gran Hotel Don Manuel.

The final day featured particularly inspiring sessions:

• Olivier Perard, on AI in Enterprise Architecture.

• Marc Alier, with Safe AI in Education – The LAMB Project, focusing on history, ethics and risks.

• Merve Astekin, with Software Maintenance with Agentic LLMs, showcasing sustainable AI projects.

The summer school concluded with an advanced workshop, Multi-Agent LLMs and Knowledge Graphs for Monitoring and Sustaining Software Systems, delivered by Adela N. Videsjorden and Simeon Andersen Tverdal.

With the success of this first edition still fresh, we are already working on the next one. We are fully confident that the second edition of our school will be as engaging and enriching as this inaugural event. Our goal is to maintain the high quality of content and the variety of discussions to establish a great meeting point for the community.

Stay tuned for upcoming announcements!
