Scaling LLM Agents Beyond Demos: Coordination Costs, Topologies, and What Actually Works
Vector Finch note: This post is inspired by the research paper On the Scaling Laws of Multi-Agent Systems (arXiv:2512.08296), and extends it with production-focused interpretation, heuristics, and architecture guidance. TL;DR (10 seconds) * Adding agents increases coordination cost faster than it increases capability. * The topology matters more than
