Asking for pairs of images instead of more than 2 images in a row helps us to avoid heavy CPU load and connection error out ;)<br /> |

## How does this work? |
|
The normal Stable Diffusion model is trained to be conditioned on text input. This version has had the original text encoder (from CLIP) removed, and replaced with |
|
the CLIP _image_ encoder instead. So instead of generating images based a text input, images are generated to match CLIP's embedding of the image. |
|
This creates images which have the same rough style and content, but different details, in particular the composition is generally quite different. |
|
This is a totally different approach to the img2img script of the original Stable Diffusion and gives very different results. |
|
The model was fine tuned on the [LAION aethetics v2 6+ dataset](https://laion.ai/blog/laion-aesthetics/) to accept the new conditioning. |
|
Training was done on 4xA6000 GPUs on [Lambda GPU Cloud](https://lambdalabs.com/service/gpu-cloud). |
|
More details on the method and training will come in a future blog post. |
