This model has a focus on fidelity, photorealism and men. Version 2 is out now as an experimental fine-tune which was trained on top of the snovel merge found in the Unstable Diffusion Discord. The purpose was to learn and experiment with EveryDream v1 using the high fidelity data sets I've hoarded.

Homoerotic v1 is not recommended, consider it archived. As well, I personally find this model better than Homoerotic Frankenstein.

Addendum: This may not work well in InvokeAI's GUI as it's missing fundamental features. Don't recycle prompts from Homoerotic Frankenstein, click "Show More" and check the prompting style of the examples.

The base training resolution was 768 and utilized aspect ratio bucketing on around 2k photographic high fidelity images of men (both sfw and nsfw) as well as a smaller subset of empty environments, various unrelated subjects, and some well-illustrated anime for hard to find concepts with the hope of lending it flexibility. There were 5 epochs although the data set differed for all but the last two.

It's responsive to booru tags, types of shots ('medium shot', 'closeup', 'long shot', etc) as well as sentences/captions. Describing more aspects of the image you want will give you better results.

The below chart was used as reference when it came to tagging a portion of the data set's shot sizes for a portion of the training. I swapped to pure booru tags after epoch 2 but they certainly still have an effect. 'long shot' and 'wide shot', not shown in this chart, can be useful to place the subject at a distance and display more of their surroundings or enhance the composition of wide resolution generations. 'foreshortening' can also have interesting effects depending on the perspective you're trying to achieve. 'depth of field' is also powerful.

Recommended quality prompt (at the least): masterpiece, best quality, highres, realistic
Recommended negative prompt: black and white, monochrome, comic, bad anatomy, bad hands, text, error, cropped, letterbox, jpeg artifacts, signature, watermark, username, artist name, censored, 1girl, 3d rendering

Certain body types may require some prompt alchemy. Try placing muscular tags in your negative prompt for less fantastic physiques. 'beefy' has always had a good effect as well as 'twink', both are self-explanatory and for some reason recognized by CLIP/BLIP.

Some common resolutions in order of frequency across the last two epochs, these may help you find a good starting point for prompting:
(640, 896), (896, 640), (704, 832), (768, 768), (960, 576), (1024, 576), (576, 960)

Dongs and actions are still a roll of the dice but things are improving.

Some sample prompts:

parameters ('indian super model' is a CLIP/BLIP suggested caption from some of my training images, it has a good effect. mixing with 'dark skin' and 'dark-skinned male' from the booru tags can sort of muddle it and make the ethnicity ambiguous. kinda cool)
