COUNT(*) queries. Good article on the same - http://work.stevegrossi.com/2015/04/25/how-to-count-with-activerecord/subject is a special variable that refers to the object being tested.

AI is everywhere but it's unclear which investments will actually move your metrics and which are expensive experiments.
Most AI projects fail at the data layer. Pipelines, quality, access all need work before LLMs can deliver value.
Your engineers are shipping product. They don't have capacity to also become AI specialists with production-grade experience.
Aging, undocumented codebases make AI integration slow, risky, and expensive. They need to move first.
