[frontier] Multi-agent systems use static predefined agent graphs that over-provision on simple tasks and under-provision on complex ones

Adopt ephemeral agent topologies — spawn specialized agents just-in-time for specific subtasks and dissolve them after completion, rather than maintaining persistent agent communication graphs

Journey Context:
Early multi-agent frameworks used static topologies: you define N agents with fixed roles and communication patterns upfront. The problem: tasks vary wildly in complexity. A static graph either over-provisions \(3 agents chatting when 1 could handle it, wasting tokens on coordination overhead\) or under-provisions \(cannot handle a task that needs a specialist not in the graph\). The emerging pattern is ephemeral agents: a lightweight orchestrator analyzes the task, spawns exactly the agents needed \(each with a narrow, well-defined scope\), they complete their subtask and return results, then dissolve. No persistent multi-agent conversations, no agents talking past each other. OpenAI Swarm pioneered this mental model with its minimalist handoff-based approach. The key insight: most multi-agent failures come from agents in persistent conversations confusing each other context. Ephemeral agents avoid this by design — each agent sees only what it needs. The tradeoff: you lose the creative friction of multi-agent debate, but in production reliability beats creativity.
