She's a model or something idk.

A few details:

It was trained on Stable Diffusion 1.5 as a base model, so it might work on most checkpoints without many alterations, my favorite checkpoint for this was Real Dream Legacy SD1.5.

Generation parameters:

Clip Skip: 1
Best weight: 0.95

Sampler: DPM++ 2M Automatic/Karras, 35 steps

If you like it, consider buying me a coffee, I'm poor.

The model can make her bicolor red/white and brown hair, but that's up to your luck so generate until you're happy.
Use adetailer.
