How does the open world in gta online differ from story mode?

Grand Theft Auto Online operates within the same fictional San Andreas and Los Santos as GTA V's story mode but transforms the open world into a multiplayer space where up to 30 players can explore, interact, and engage in cooperative or competitive game modes. While story mode follows a linear narrative with predefined protagonists (Michael, Trevor, Franklin), Online allows players to create and customize their own silent protagonist. The online world evolves over time through regular updates, introducing new content, vehicles, and activities, whereas story mode remains static with its fixed missions and plot. Online emphasizes player-driven experiences like heists, races, and freemode events, contrasting with story mode's scripted missions and character-driven plot. Additionally, Online features a persistent world where player actions and progress are shared across sessions, while story mode is a single-player experience with isolated progression.
