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? 👇

We need to produce a short comment, casual, start with lowercase, specific reaction or question about the video content. No quotes, no labels, no hashtags, no markdown. No URLs. Must be short, one or two sentences. Use casual voice. Avoid formal marketing. Must not start with "Great video". Must be about the content: multi-agent orchestration, question about tradeoffs, maybe ask about scaling cost. Let's craft. "so does adding more agents actually degrade performance after a point, or is it just the overhead
As per me, use agents where they actually add value. not everything needs an agent everywhere — sometimes a simple workflow is more efficient, cheaper, and easier to maintain. plus, the application shouldn’t go down just because the AI/agent layer is temporarily unavailable. Fallback is important!
