What content transfers between gta v story mode and online?

Grand Theft Auto Online is the multiplayer component of Grand Theft Auto V, released separately on multiple platforms including PlayStation 3, Xbox 360, PlayStation 4, Xbox One, Windows, PlayStation 5, and Xbox Series X/S. The online mode operates as a separate experience from the story mode, with players creating their own customizable characters to explore the fictional state of San Andreas alongside up to 30 other players. While the game shares the same open-world setting, GTA Online does not transfer story mode progress such as mission completions, character development, or narrative choices. Some cosmetic items, vehicles, and premium content can be purchased in both modes and may be accessible across them, but core gameplay progress and story elements remain isolated to their respective modes. The online component features its own set of missions, activities, and progression systems independent of the single-player narrative.
