I spent the last few days reading recent multiagent papers (late 2025-early 2026), and one result changed how I think about a lot of agent systems. A UBC team showed that many multiagents can be compiled into a single agent with skills, with much lower token use and latency and similar output quality. That does not mean multiagent is useless, it means some of what we call specialization is really a way to keep routing under control. The part I found most useful is where that simplification stops working. Once the tool library gets crowded enough (60-80 skills), the model starts confusing nearby actions. At that point, an “agent” can be less like a role and more like a clean namespace. I wonder why such a specific cliff was found. That fits a lot of production stacks I have seen, Planner, researcher, coder, reviewer can be real specialization. Sometimes it is, but sometimes it just means one model gets messy when it has to manage too many tools and too much state in one place. And I wondered then how many of these can be “compiled away” to a single agent with skills. I read a wider batch of papers after that one, including ROMA, SkillOrchestra, Vision Wormhole, EmCoop, Agentic Memory, EMPO2, and the scaling paper. My takeaway is simple: before adding more agents, ask what problem they are actually fixing. EXCEPTIONS : There are still cases where multiagent looks real to me, especially mixed model setups, trust boundaries, embodied coordination, and exploration. But a lot of same-model tool stacks look more like temporary scaffolding than an end state. And what about Swarms? Seems like the research also has a new place for them. Use them to produce useful trajectories that will help you distill to your agent. Usually by further training according to research. But I wonder if a SWARM is also possible good REVERSE start, before consolidating the swarm learnings to a leaner system or even just one agent with skills/tools.
