A study examining AI agent costs found that the "harness," which dictates the execution system, tool schemas, and conversation history, is the primary driver of operational expenses, not the AI model itself. The research suggests that organizations should prioritize benchmarking harnesses over standardizing tools when adopting agent platforms. Focusing on the harness allows for better cost control by managing factors like prompt complexity, tool definition payloads, and retry logic, which significantly impact per-turn input costs and overall completion expenses.

IMPACT Focusing on the execution harness rather than just the AI model can lead to significant cost savings and more predictable operational expenses for AI agent deployments.
