The content_models table is a normalisation table for content model names. They are referenced from the content table.
In PHP code, normalisation is managed via NameTableStore .
It was introduced in MediaWiki 1.31 as part of the Multi-Content Revisions project; see Multi-Content Revisions/Content Meta-Data for details. During migration from older versions, the table is populated by populateContentTables.php (run automatically by the upgrade script).
