What are Resource limits for CI jobs on GitLab.com? RAM? CPUs

Hi @westshawn and welcome to the GitLab Community Forums.

If you’re using the GitLab.com autoscaling shared runners, I believe the runners have 1CPU, 4GB RAM, and 22Gb of storage (16Gb available).

You also have the option to install GitLab Runner on your own infrastructure use it to run your CI jobs. Doing this, there is essentially no resource limit, as it circumvents any limitations of using shared resources.
