Data from 13,000+ OfficeQA runs reveals an early warning sign for AI agent failure: incorrect agents take up to 50% more steps, consume 40% more compute, and incur 40% higher costs per episode compared to successful ones. Failed trajectories not only take longer but waste significantly more compute, tokens, and money. When an agent takes more actions without making real progress, it is a useful indicator that it is heading towards failure.
