i use a open source model that generates whatever image i want and yeah the set up is easy:
open google collab and type this code - !pip install pygit2==1.15.1
%cd /content
%cd /content/Fooocus
!python entry_with_update.py --share --always-high-vram now change the runtype to T4-GPU, you will have a link of gradio to access the server in 3-4 minutes now use the model to generate hyper realistic images.
this ai - https://preview.reve.art/ is also the best ai image generation I've seen so far as when it comes to generating complex scenes. all the image below is generated by that open source model, so have fun.
