AI agent dev burns 200k GitHub runner-minutes a month — how do you tame CI costs?

Hairy-Supermarket120 · reddit · 2026-10-03

A developer running many cheap AI agents with rigorous verification — Playwright/Chromium tests plus full page-render screenshots uploaded to GitHub Artifacts, visually inspected by ChatGPT via the GitHub MCP connector — spends 60 minutes of CI per PR and 200k runner-minutes a month, far beyond included quotas.

They've already moved some workloads off GitHub-hosted runners but ask for more: self-hosting, ephemeral runners, shrinking the test matrix, or running expensive suites only post-merge. Useful cost benchmark for anyone automating agent development.
