微調 Black Forest Labs 的 Flux 模型雖然門檻低，但要達到頂尖效果仍需技巧。Replicate 官方分享了利用「合成數據」優充微調的技術，核心在於使用視覺語言模型（VLM）為訓練集自動生成極其詳盡的合成標籤（Synthetic Captions），以及利用 AI 生成多樣化圖像來擴充訓練集。這些方法能有效防止模型過擬合，並顯著提升 Flux 對複雜提示詞的理解與執行能力。
Fine-tuning the open-source image generation model Flux.1 has become a highly sought-after capability for creators and developers alike. However, relying solely on a small set of raw images often leads to model overfitting or an inability to accurately interpret complex prompts. This guide published by Replicate dives deep into how to use "synthetic data" to break through these bottlenecks and significantly improve the quality of Flux LoRA fine-tuning.
