# 混合推理
12+
13+
**通过混合推理赋能本地 AI 构建者**
14+
15+
> [!TIP]
16+
> 混合推理是一项[实验性功能](https://huggingface.co/blog/remote_vae)。
17+
> 可以在此处提供反馈[此处](https://github.com/huggingface/diffusers/issues/new?template=remote-vae-pilot-feedback.yml)。
18+
19+
## 为什么使用混合推理?
20+
21+
混合推理提供了一种快速简单的方式来卸载本地生成需求。
22+
23+
- 🚀 **降低要求:** 无需昂贵硬件即可访问强大模型。
24+
- 💎 **无妥协:** 在不牺牲性能的情况下实现最高质量。
25+
- 💰 **成本效益高:** 它是免费的!🤑
26+
- 🎯 **多样化用例:** 与 Diffusers � 和更广泛的社区完全兼容。
27+
- 🔧 **开发者友好:** 简单请求,快速响应。
28+

# 入门:使用混合推理进行 VAE 编码
2+
3+
VAE 编码用于训练、图像到图像和图像到视频——将图像或视频转换为潜在表示。
4+
5+
## 内存
6+
7+
这些表格展示了在不同 GPU 上使用 SD v1 和 SD XL 进行 VAE 编码的 VRAM 需求。
8+
9+
对于这些 GPU 中的大多数,内存使用百分比决定了其他模型(文本编码器、UNet/Transformer)必须被卸载,或者必须使用分块编码,这会增加时间并影响质量。

一个辅助方法简化了与混合推理的交互。
