触发词
LoRA训练中用于绑定角色视觉特征的自定义词汇，作为高维语义锚点压缩存储角色的隐含视觉特征，应选用基础模型词汇表中不存在的无意义字符串
Timeline (last 90 days)
A trigger word is a token anchor that activates the target concept during LoRA inference; during training it appears repeatedly as part of the annotations, and the model binds it to the target style or character; during inference, adding the word to the prompt reliably evokes the corresponding features.
Trigger word design should avoid common words that already have strong semantics in the base model; a common practice is to use rare concatenated words or proper nouns, and before training to test with the base model whether the word already has an obvious prior response.
