“they work in a sequence. So they don't work in a swarm or parallel. The agents work in sequence and everyone accomplishes something and passes it to the next one. uh we actually found that if you do this you end up with more fresh context and kind of fresh head.”

Factory’s “missions” are long-running sessions, some lasting weeks, where an orchestrator agent hands work to worker agents. Workers run one after another rather than as a parallel swarm, and each one can still use parallel sub-agents for small tasks such as research. Quoted from YouTube’s auto-generated captions.
