# Templates-锐利激发（FLUX.2-klein-base-4B）
本模型是 [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio) 开源的 Diffusion Templates 系列模型之一。该模型能够通过调整 `scale` 参数，精准控制生成图像的锐度与细节表现力。
## 效果展示
> **Prompt:** A cat is sitting on a stone.
| scale=0.1 | scale=0.8 |
|:---:|:---:|
|  |  |
---
> **Prompt:** A close-up of a person's eyes, looking at the camera, reflections in the pupils, highly aesthetic.
| scale=0.1 | scale=0.8 |
|:---:|:---:|
|  |  |

> **Prompt:** A beautifully decorated frosted cupcake.
| scale=0.1 | scale=0.8 |
