Fast LoRA inference for Flux with Diffusers and PEFT

Practical AI: Tools, Models & Frameworksinference

What changed

In this post, we take the Flux.1-Dev model for text-to-image generation because of its widespread popularity and adoption, and how to optimize its inference speed when using LoRAs (~2.3x). It has over 30k adapters trained with it (as reported on the Hugging Face Hub platform). Therefore, its importance to the community is significant.

Why it matters

A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
