Is there any single player content in gta online?

Grand Theft Auto V Online is designed as an online multiplayer experience that requires at least one other player to participate in missions, heists, races, or other activities. While the free‑play world can be explored alone, all structured content—such as story missions, heist setups, and special events—needs a second player or additional participants. The game does not offer a true single‑player mode or missions that can be completed in isolation. Players looking for a solo experience would need to use the story mode of Grand Theft Auto V instead.
