The main debate in agent architecture is single versus multiple agents, and the emerging resolution is that a single orchestrator owning the full context and spawning isolated, short-lived sub-agents works best, while sub-agents that communicate directly tend to produce conflicting results.

The article describes the 2025 debate between Cognition (arguing against multi-agent designs) and Anthropic (showing multi-agent scoring 90% higher on research tasks), and distills the resolution: one orchestrator spawns isolated sub-agents, avoiding direct sub-agent communication that causes conflicts. ✦ AI generated

A single orchestrator owns the full context and spawns isolated, short-lived sub-agents, each of which completes one task and returns a summary. The lesson to understand is that small, focused agents work best under firm orchestration, while sub-agents that communicate directly with one another tend to produce conflicting results.
