This model was trained on the loading screens, gta storymode, and gta online DLCs artworks.
For some reasons, the model stills automatically include in some game footage, so landscapes tend to look a bit more game-like.
To reference the art style, use the token: gtav style

There is already an existing model that uses textual inversion. This is trained using Dreambooth instead, whether or not this method is better, I will let you judge.
