Ghost agent ran all night, cut per-turn cost from 20¢ to 4¢ with zero chatter
BLUECOW009 · x · 2026-09-07
The author let the Ghost agent run autonomously through the night on their local machine and reports per-turn cost dropped from 20¢ to 4¢ — an 80% reduction. Notably, Ghost made no comments at all while running, which the author takes as evidence the system works as intended without wasteful output. A short first-hand data point on the real economics of leaving agents running in the background.
