The model should require less token in both positive and negative prompt to get realistic results, now.
Low CFG scale ~2.5 gives a nice photo-realistic look to the picture and allows you to go a bit crazier with the weighting in the prompts.
Heun sampler with as low as 8 steps also gives quite nice results.
Initially built to create lifelike portraits of characters from the novel I'm working on, whose title is Endless, thus the name of the model.
This is a rather complex merge, and sadly I did not took notes.
Prompting
Example of prompt for a realistic image (replace {prompt} with your subject):
professional photograph {prompt} ((video grainyfilm)), natural cinematic lighting, ((professional photo highly defined)) realistic, best quality, photo-realistic 8k, best quality, masterpiece, realistic, photo-realistic
Example of negative prompt for a realistic image:
(text, signature, watermark, logo, ux, ui:1.3), monochrome, (2D), (3D), ((camera)), ((cartoony)), (CGI), ((drawing)), ((lowres)), ((painting)), ((sketchy)), ((The Sims)), (ugly), ((blur)) (worst quality, low quality, normal quality:1.3), lowres
NSFW content is possible, nsfw, uncensored in the negative prompt can help get rid of them.
