Adapting Stable Diffusion efficiently with LoRA

Summary

LoRA trains small additional matrices instead of all the weights of a diffusion model. This lowers memory requirements and produces compact adapters that can be distributed separately. LoRA freezes the original model weights.

Ideas

  • Adapters separate an adaptation from the unchanged base model.
  • Small trainable parameter packages make variants, versioning and exchange easier.

Insights

  • Compact adaptations make variants affordable and at the same time increase the need for clean provenance management.

Facts

  • The resulting adapter files are considerably smaller than complete model copies.

Critique

  • Small adapters can still memorise problematic training data or amplify unwanted styles.

Recommendations

  • Keep the base model revision, a description of the training data and the adapter parameters together.

Serving thirty LoRA models with one server

Text Generation Inference loads many LoRA adapters on top of a shared base model and serves them together. This avoids complete model copies and improves utilisation. The demonstration serves 30 LoRA models through one TGI instance.

Quantisation backends for diffusion models

The article compares several quantisation routes for Diffusers and their effect on memory, speed and image quality. Because of their various components, diffusion pipelines have different requirements from pure LLMs. Diffusers supports several backends via quantised model components.

Comparing RoBERTa, Llama 2 and Mistral with LoRA

The article compares three model families on classifying disaster tweets with LoRA. It shows that a larger generative model is not automatically the best or most economical classification solution. The study uses the Disaster Tweets data set.
