Description
Gigafractal2 Diffusion is a latent text-to-image diffusion model based on the original StabilityAI Stable Diffusion v2.0 and then fine-tuned on 40 images origanally made with another diffusion model named 'Disco Diffusion' using Dreambooth. This model has been created to explore the possibilities and limitations of Dreambooth training with training steps increased much more than usual and to overcome biases in the model created by the text incoder's token associations. The purpose of this model is to provide the biomorphic fractalism effect present in Disco Diffusion, but without the bias to 'Disco parties' and especially 'discoballs' for which [the model by snek](was known for).
To use this style in your generations, add gigafractal artstyle to the prompts.

Model Description
The model originally used for fine-tuning is Stable Diffusion V2-0, see their infopage https://huggingface.co/stabilityai/stable-diffusion-2.
The current model has been fine-tuned with a learning rate of 1.0e-6 for 2040 steps using Dreambooth on Disco Diffusion produced images.
