The tutorial addresses a central tension in multi-agent systems built on large language models (LLMs). Such systems can handle demanding reasoning, planning, and problem-solving tasks, but making them both accurate and economical to run is still difficult. The presenters organize the material around three themes. The first is building capable individual agents on small, inexpensive models, using model distillation, dynamic routing between models, and serving methods that reduce memory and computation. The second is how agents interact. It covers improving collective reasoning and decisions through prompt and graph optimization, curbing sycophancy (agents uncritically agreeing with each other or the user), and structured LLM-based frameworks. The third surveys deployments in industry, healthcare, quantum computing, and other scientific fields. The tutorial's value is a consolidated overview of methods for scalable, resource-aware agent systems rather than a single empirical finding. ## Key points - Published in the ACL 2026 Proceedings, Volume 5 (Tutorial Abstracts), pages 5–6. Tutorial materials are at xuanwang91.github.io/2026-07-02-acl26-tutorial. - The presenters are Xuan Wang (Virginia Tech), Shuxiang Cao (NVIDIA; University of Oxford Physics), Yuchen Zhuang (Google DeepMind) and Wenqi Shi (UT Southwestern Medical Center). - The single-agent efficiency toolkit covers model distillation, dynamic routing, and memory- and compute-saving serving for constrained resources. - For coordinating multiple agents, the toolkit includes optimizing both prompts and agent interaction graphs, reducing sycophantic behavior, and frameworks that give LLM agents a structured way to collaborate. - The application areas are industry, healthcare, quantum computing, and other sciences. The abstract reports no quantitative results. *Our summary of the paper, in our own words — not its text.
