Multi-agent orchestration isn't "more powerful." It's usually a more expensive way to get worse reasoning.

Every agent-to-agent handoff is a lossy compression step. The receiving agent never sees the nuance the previous one worked through — only its sanitised summary. Google's own research found multi-agent coordination dropped sequential reasoning performance by 39–70%. A Sber whitepaper clocked ~15x the token usage versus single-agent chat.

Multi-agent earns its overhead in exactly one scenario: the work is genuinely parallel, or too large for a single context window. Everything else? A single agent with good tools and enough context will out-reason your swarm — at a fraction of the cost.

The "more agents = more intelligence" playbook is hype math, not engineering math. What do you think? 👇
