[v3.1 is still in further testing. Updates regarding new findings will be updated in the "About this version" section]

UrangDiffusion v3.1 (oo-raw-ng Diffusion) is the first UrangDiffusion version that utilize Animagine XL 4.0 as the base.

The name “Urang” comes from Sundanese, meaning “We/Our/I.” The history behind the name is to make the model not only suitable for me but also for many people. Another reason is that I use many resources (training scripts, dataset collecting scripts, etc.) from other people. It’s unfair to claim this model as “my sole work.”

Standard Prompting Guidelines

• Prompting guide:

  

• Default negative prompt: lowres, bad anatomy, bad hands, text, error, missing finger, extra digits, fewer digits, cropped, worst quality, low quality, low score, bad score, average score, signature, watermark, username, blurry

• Default configuration: Euler a with around 25-30 steps, CFG 5-7, and ENSD set to 31337. Sweet spot is around 28 steps and CFG 6.

Training Configurations

Finetuned from: Animagine XL 4.0 Base (NOT 4.0-Zero)

Finetuning:

• Dataset size: ~1,600 images

• GPU: 1xA100 80GB

• Optimizer: AdaFactor

• Unet Learning Rate: 1.25e-6

• Text Encoder Learning Rate: N/A (Turned off)

• Batch Size: 48

• Gradient Accumulation: 1

• Warmup steps: 5%

• Min SNR: 5

• Epoch: 15

FAQ

• Q: Images are sometimes noisy.

• A: This is a common issue with Animagine XL 4.0 models in general. The base model is trained with only 10 epochs, which lead to the model being undertrained. Unlike Initial N or Initial I model that are trained with more resources.

• Q: Hires fix model?

• A: Check out the cover image metadata, you'll find it there.

• Q: Initial N/Initial I is better.

• A: Just leave and do not use the model. Simple. No need to announce your departure. Except you're willing to leave a constructive feedback or willing to fund future projects.
