More agents = more intelligence?
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…
The claim that more agents equate to more intelligence is often overstated and frequently results in a more costly and less efficient approach to problem-solving. Each handoff between agents leads to a loss of nuance and detail, as the receiving agent only receives a summary of the previous agent's work. Research from Google indicates that multi-agent coordination can reduce sequential reasoning performance by up to 70%.
In fact, a Sber whitepaper found that multi-agent systems require up to 15 times more tokens compared to single-agent chat. Multi-agent systems only provide a significant advantage in scenarios where the work is genuinely parallel or exceeds the context window capacity of a single agent. However, for most tasks, a single well-equipped agent with ample context can outperform a swarm of agents in terms of reasoning abilities, all while being more cost-effective.
The notion that "more agents = more intelligence" is more hype than practical engineering solutions.
