About JoePenna/Dreambooth-Stable-Diffusion
This open-source repository implements DreamBooth subject fine-tuning for Stable Diffusion using textual inversion. It includes tweaks focused on training faces, objects, and styles. The author describes the tool as designed for digital artists to train their own characters and styles, and for people to train their own likenesses, with a stated goal of helping filmmakers and concept artists generate initial visual ideas.
Training requires a GPU with 24GB of VRAM, such as a 3090, according to the source. Training will be slower, and no other program should be running. For users without that hardware, the repository includes Jupyter notebooks tailored to runpod.io and vast.ai, and it states support for a Google Colab notebook. The author strongly discourages training other people's art without explicit permission or a public statement about this technology, and recommends against using artists' names in prompts. The source also states that the implementation does not fully implement Google's ideas on preserving the latent space. Pricing is unknown.
