How does the open world freedom compare in gta online versus story mode?

The verified evidence available focuses on the history of Western role-playing video games, covering their origins on mainframe university computer systems in the 1970s, their popularization through titles like Ultima and Wizardry in the 1980s, and their Golden Age in the mid-to-late 1980s. The evidence mentions that the genre's popularity declined in the mid-1990s due to challenges with changing fashion, hardware evolution, and increasing development costs. However, this evidence does not contain any specific information about Grand Theft Auto's open world mechanics, the differences between GTA Online and story mode, or any comparison of freedom levels between these game modes. Without relevant evidence, I cannot provide an informed comparison of open world freedom between GTA Online and story mode.
