UnverifiedToo many LoRA training steps leads to overfitting, manifesting as generated results that closely resemble the training set, with rigid character expressions and fixed poses.76% similarUnverifiedLoRA achieves parameter-efficient fine-tuning by superimposing low-rank decomposition matrices onto pre-trained model weights, delivering the highest consistency, but each new character requires dozens of reference images and hours of training, resulting in high engineering costs.70% similarUnverifiedLoRA训练中rank值通常建议从4-16或4-32的安全区间开始实验，过高的rank值会导致模型记忆训练细节而非抽象人物特征69% similarUnverified领域适应的标准路径是微调，使用 LoRA 或全量微调对预训练权重进行领域适应，以 WER（词错误率）指标评估效果67% similarUnverifiedModels with more parameters and newer architectures (such as Flux 2 Dev) are not necessarily superior to mature older models on specific tasks such as character LoRA training.66% similar
