2nd edition of Sustainability in LLM-assisted Software Engineering (SILAS). The SILAS workshop brings together researchers, practitioners, and policymakers to explore how sustainability intersects with software engineering practices and large language models (LLMs). We encourage participation regardless of whether you publish at SILAS, as we appreciate the value of diverse insights and active dialogue.

LLMs are rapidly becoming part of everyday software engineering workflows. Their integration into tasks such as requirements, design, implementation, testing, and maintenance—together with large CI/CD pipelines—raises important questions about energy use and resource consumption. Understanding and reducing this footprint is increasingly urgent.

This second edition features a keynote, paper presentations,and structured roundtable discussions focused on identifying challenges and opportunities for more sustainable LLM-assisted software engineering. SILAS welcomes contributions offering empirical insights, efficiency benchmarks, behavioral profiling of LLMs, lifecycle-oriented tooling, prompting strategies, and industrial experiences, see the website (https://silas-26.github.io/) for more information. Accepted research and NIER papers will appear in the official ICT4S’26 workshop proceedings. In addition, we invite short industrial experience summaries, case studies, and demonstration notes to enrich workshop discussion; these contributions are intended for interaction during the workshop and will not be part of the formal proceedings. A key goal of SILAS is to build a strong scientific foundation for this emerging area. Following the workshop, the outcomes of these discussions will be incorporated into a scientific paper for submission, ensuring that the insights generated are transparent and accessible to a broader audience.
