Gigafractal Diffusion SD2版本SafeTensors (ID: 1233)

Originally posted to HuggingFace by kabachuha

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).

The regularization dataset of 200 AI-generated images had been produced in AUTOMATIC1111's webui with the following prompt which may have had a positive effect on the resulting quality.

Downstream Uses

This model can be used for entertainment purposes and as a generative art assistant.

Acknowledgements

• Inspired by snek's work
• This project would not have been possible without the incredible work by the CompVis Researchers, Disco Diffusion, Deforum devs and all the artists who made the content for training even if they were an AI.
• The author is grateful to snek for the provided dataset.

Subjective opinion: the quality of the output images is comparable to that of another text2image generator, Midjourney.
