Multi-Agent Teams Barely Beat Solo Agents but Cost Up to 5.1x More Tokens
The Decoder · rss · 2026-10-11
Per The Decoder, Vals AI's research finds that teams of AI agents barely outperform solo agents while costing up to 5.1x more.
- Out of four tests with GPT-6 Sol and Claude Opus 5.5, only one showed a measurable quality gain.
- Anthropic's own data backs this up: beyond ten agents, quality plateaus while token costs keep climbing.
Takeaway: piling on more agents wastes compute — "more is better" doesn't hold in agent orchestration.
