| # Keras-Dreambooth Galaxy Mergers 🪐🤗 | |
| This is a Keras Dreambooth model fine-tuned to images of galaxy mergers taken with the [Hubble Space Telescope](https://en.wikipedia.org/wiki/Hubble_Space_Telescope) (credit [ESA/Hubble](https://esahubble.org/images/)). | |
| The model, part of the [Keras Dreambooth Sprint](https://github.com/huggingface/community-events/tree/main/keras-dreambooth-sprint) trained by lposti, can be found in [keras-dreambooth/dreambooth-galaxy-mergers](https://huggingface.co/keras-dreambooth/dreambooth-galaxy-mergers). | |
| The model should be used with a prompt containing `sks galaxies merging`. A typical prompt for this model is `image of sks galaxies merging in space`. | |
