本文介紹如何利用 Hugging Face 的 Diffusers 與 PEFT 庫，大幅加速 Flux.1 圖像生成模型的 LoRA 推論。透過融合 LoRA 權重（Fusing）、使用 torch.compile 進行編譯優化，以及利用 PEFT 的動態適配器管理，開發者可以在不損失畫質的前提下，顯著降低推論延遲並實現多 LoRA 的快速切換，非常適合生產環境部署。
This technical guide from Hugging Face takes an in-depth look at how to accelerate LoRA (Low-Rank Adaptation) inference for Flux.1, the powerful open-source image generation model released by Black Forest Labs. As Flux.1 gained popularity in the community, fine-tuning and deploying custom LoRAs became a highly sought-after capability — but its massive 12 billion (12B) parameter architecture also introduces significant computational overhead and latency.
