This model was trained on the official art images of the GTA 5 game, which usually appear on the loading screens. These arts include images of people, animals, and various objects that are usually part of a general picture or background.
Stable Diffusion v1-5 was used for training, also about 30 concept images and 1000 regularization images for style training.
Due to the use of Google Colab resources, you do not need to have a GPU and you can freely experiment on your concepts.
To select the optimal settings before training, I recommend using this
