AI agent teams waste massive tokens for barely measurable quality gains, research finds

Intel Summary
Research from Vals AI indicates that multi-agent AI teams yield minimal performance improvements over single agents while increasing token costs by up to 5.1 times. Testing across GPT-6 Sol and Claude Opus 5.5 demonstrated measurable gains in only one of four evaluations. The findings align with Anthropic data indicating that agent performance plateaus beyond ten agents despite continually rising token consumption.
Why It Matters
Multi-agent architectures can significantly inflate inference and operational costs without delivering commensurate accuracy or output quality. Enterprise builders and technical leaders evaluating swarm or collaborative agent setups must weigh the steep token overhead against negligible performance improvements over optimized single-agent workflows.
