Endjourney is aimed to be the ultimate model someday superseding Midjourney. ^^ It is pretty good at everything. The possibilities of Endjourney are truly endless. Limited by your imagination.
Just use it instead of the SDXL 1.0 base model. No refiner needed.
You can try out very simple prompts or very descriptive ones. It is responsive to both.
Feel free to share your creations to provide feedback on improving the model.
