> WHAT: Trend-based automatic resource class scaling (opt-in) < The ability for CircleCI to automatically scale a job up to the next resource class based on that job's historical usage trends. If a specific CI job shows memory or CPU usage trending upward over time — i.e., consistently maxing out its current resource class — CircleCI would auto-bump it to the next class up without requiring a manual config change. > WHY: < As usage scales — steadily increasing volume, new services and projects added over time — teams want jobs to right-size themselves automatically, avoiding the manual overhead of monitoring and adjusting resource classes as workloads grow.
