Can you play gta online on the same save file as story mode?

The verified evidence focuses exclusively on Grand Theft Auto V's single-player story mode, detailing its 2013 release by Rockstar North, the three protagonists (Michael De Santa, Franklin Clinton, Trevor Philips), and the fictional San Andreas setting. There is no mention of Grand Theft Auto Online or its relationship to story mode save files in the provided text. Since the evidence does not cover this specific technical aspect of the game, no definitive conclusion can be drawn about save file compatibility between modes.
