将选定的 .safetensors 放入 ComfyUI 的 models/loras，在 LoRA 加载节点中选择它，并在提示词中加入 xiaoling。以下示例统一使用 LoRA strength 1.0。

这些权重训练于 Krea 2 Raw；下面的展示图片使用 Krea 2 Turbo INT8 进行推理。权重保留发布目录中的原始文件名，对应之前测试时标注为 v2 的同一份权重。

测试提示词

P1 · 图书馆正面肖像 · Seed 101

A candid waist-up portrait of xiaoling, a young Chinese woman, seated in a quiet modern library and facing the camera with a composed expression. She wears a dark green knit sweater. Soft, cool daylight fills the room, while bookshelves and a reading area blur gently in the background. Preserve her recognizable facial identity and natural skin texture.

P2 · 地铁站四分之三侧面肖像 · Seed 102

A realistic portrait of xiaoling, a young Chinese woman, at a three-quarter angle turned toward the left side of the frame in a modern metro station. She looks thoughtfully toward the platform, wearing a deep red coat and a dark scarf. Cool station lights and distant commuters form a softly blurred background. Keep her facial identity consistent.

P3 · 美术馆回望 · Seed 103

A candid waist-up portrait of xiaoling, a young Chinese woman, walking through a contemporary art museum and glancing back toward the camera. She wears a light tan trench coat over a charcoal high-neck top. Diffuse skylight, pale gallery walls, and a few distant artworks create a clean, quiet setting. Maintain her recognizable facial features.

P4 · 屋顶自然笑容 · Seed 104

A lively portrait of xiaoling, a young Chinese woman, laughing naturally with her face turned slightly toward the right side of the frame. She wears a deep green cardigan on a rooftop at twilight. Cool blue evening light and softly blurred city lights create a gentle cinematic atmosphere while her identity remains clear.

P5 · 山间侧脸 · Seed 105

A realistic side-profile portrait of xiaoling, a young Chinese woman, gazing toward the left side of the frame from a mountain overlook at dawn. A light breeze moves her shoulder-length dark hair. She wears a red wool coat and a knitted scarf, with a distant pale blue landscape softly out of focus. Preserve her facial identity.

P6 · 更换发型和服装 · Seed 106

A realistic portrait of xiaoling, a young Chinese woman, shown in a three-quarter view with her face turned toward the right side of the frame. Give her a noticeably different hairstyle, with her dark hair worn loose around her shoulders instead of gathered into a bun, and a simple modern outfit different from her usual clothing. Use a clean, softly lit background. Keep her facial identity consistent.

H · 侧脸短波浪发型 · Seed 105

A realistic side-profile portrait of xiaoling, a young Chinese woman, facing the right side of the frame with her facial features clearly visible in profile. Her dark hair is worn in a short, loose, softly wavy bob ending at her jawline, parted to one side, with no hair tied back. She wears a simple navy coat and a cream scarf. Cool soft daylight and a blurred modern city street create the background. Preserve her recognizable facial identity and natural skin texture.
