A fine-tuned version of Stable Diffusion conditioned on CLIP image embeddings to enabel Image Variations.

Put in a text prompt and generate your own Pokémon character, no "prompt engineering" required!
If you want to find out how to train your own Stable Diffusion variants, see this example from Lambda Labs.

Trained on BLIP captioned Pokémon images using 2xA6000 GPUs on Lambda GPU Cloud for around 15,000 step (about 6 hours, at a cost of about $10).

Ensure that NVIDIA container toolkit is installed on your system and then run the following:
git clone https://github.com/LambdaLabsML/lambda-diffusers.git
cd lambda-diffusers/scripts
make benchCurrently xformers does not support H100. The "without xformers" results below are generated by running the benchmark with --xformers no (can be set in scripts/Makefile)
With xformers, raw data can be found here.
Without xformers, raw data can be found here.
H100 MIG performance, raw data can be found here.
