The AI agent cost guides say $200 a month. Mine has cost $5.

Developer Suman Debnath has challenged prevailing industry estimates that suggest running a personal AI agent stack costs between $185 and $480 per month. By building 'MIGI,' a fleet of agents orchestrated via cron-scheduled GitHub Actions and utilizing a multi-provider fallback strategy, Debnath has maintained a functional system for two months at a total cost of under $5. The article highlights that high costs often stem from inefficient architectures—such as using expensive frontier models for every task—rather than the inherent cost of AI itself. Debnath argues that most agent failures are not due to model intelligence, but rather infrastructure issues like poor error handling, silent scheduling failures, and misconfigured fallback chains. By prioritizing free tiers and robust, unattended engineering, the project demonstrates that personal AI agents can be operated sustainably and affordably without relying on costly managed platforms.
