Anatomy v1.0

Overview

Someone needed to fix SD 2.X, so here it is: Anatomy v1.0, an AI image generation model that excels at creating photorealistic images of humans.

With 18.5k training steps on a dataset of 3000 high quality images, Anatomy v1.0 is capable of generating images with exceptional attention to detail, including accurate anatomy and poses. Whether you need a full body shot or a beautifully rendered hand, Anatomy v1.0 has you covered. It can even handle NSFW material with ease. Give it a try and see the results for yourself.

Examples

All examples below are straight from the model, no upscaling, hi-res fix, inpainting, etc. Cherry-picked best 1 of 9. Check the image metadata for the exact generation parameters. Looks like Imgur stripped that. They're all Euler A, 20/28 steps, CFG 6, ENSD 31340. I'll get the images reuploaded somewhere else.

Tips

  • A lot of the data was scraped from Reddit, with the subreddit names intact. It's worth trying various subreddit names and seeing their effects.
  • Here's my default negative prompt for SD 2.1, this also works well for Anatomy v1.0: (monochrome:1.3), (oversaturated:1.3), piercing, child, bad hands, lowres, 3d render, longbody, wide hips, narrow waist, disfigured, kitsch, ugly, cross eyed, squinting, grain, Deformed, blurry, bad anatomy, poorly drawn face, mutation, mutated, extra limb, ugly, poorly drawn hands, missing limb, floating limbs, disconnected limbs, malformed hands, blur, out of focus, long neck, disgusting, poorly drawn, childish, mutilated, , mangled, old, surreal
  • Some typical settings I use for generating: Steps: 28, Sampler: Euler a, CFG scale: 6, Size: 640x896, ENSD: 31340
  • A lot of the time (not always) perfect hands fixes broken hands, and detailed eyes fixes wonky faces.
  • Anatomy v1.0 should be used with this config YAML: https://github.com/Stability-AI/stablediffusion/blob/main/configs/stable-diffusion/v2-inference-v.yaml
  • Please try fine-tuning off of this. I haven't tried it and have no idea what will happen.

Limitations

  • It's hard to find large amounts of high quality data for men, so any of the bias below apply extra for men. A lot of the data it does have is largely from sources aimed at gay men, and this bias is visible in the model.
  • The model is biased towards over-sexualized images. I'm aiming to fix this by including more data scraped from fashion websites in the next version.
  • If not prompted for an ethnicity, the model tends to generate West-Asian looking men, and vaguely Mediterranean women. I think it will be possible to get more diversity by including more data sources in the next run. This doesn't seem to be an issue when prompted for an ethnicity.
  • The model sometimes generated text (this can be seen in one of the examples). I'm going to label these images using a text-detection model for the next run.

Comparisons with SD 1.5 and SD 2.1

All results are fixed seed (starting at seed 0), non-cherry picked. Resolution is 640x896, so the SD1.5 examples use hi-res fix.
