Computer Use Is 45x More Expensive Than Structured APIs
A benchmark analysis reveals that vision-based AI agents operating through user interfaces cost approximately 45x more than structured API-based agents for the same task, requiring 550k input tokens and 17 minutes compared to 12k tokens and 20 seconds for API calls. The fundamental architectural limitation is that vision agents must capture and analyze screenshots for every interaction, creating inherent inefficiency that improves models cannot resolve, while API-based agents receive structured responses that enable deterministic, predictable execution. This has critical implications for IT organizations: building structured APIs for internal tools, though initially viewed as expensive engineering overhead, is substantially cheaper than the ongoing token costs of vision agents at scale.
