 ## Introduction
 
 DiffSynth Studio is a Diffusion engine. We have restructured architectures including Text Encoder, UNet, VAE, among others, maintaining compatibility with models from the open-source community while enhancing computational performance. We provide many interesting features. Enjoy the magic of Diffusion models!
 
 Until now, DiffSynth Studio has supported the following models:

 ## News
+- **December 31, 2024** We propose EliGen, a novel framework for precise entity-level controlled text-to-image generation, complemented by an inpainting fusion pipeline to extend its capabilities to image inpainting tasks. EliGen seamlessly integrates with existing community models, such as IP-Adapter and In-Context LoRA, enhancing its versatility. For more details, see [./examples/EntityControl](./examples/EntityControl/).
+  * Paper: [EliGen: Entity-Level Controlled Image Generation with Regional Attention](https://arxiv.org/abs/2501.01097)
+  * Github: [DiffSynth-Studio](https://github.com/modelscope/DiffSynth-Studio)
+  * Model: [ModelScope](https://www.modelscope.cn/models/DiffSynth-Studio/Eligen)
+  * Training dataset: Coming soon
+
+- **December 19, 2024** We implement advanced VRAM management for HunyuanVideo, making it possible to generate videos at a resolution of 129x720x1280 using 24GB of VRAM, or at 129x512x384 resolution with just 6GB of VRAM. Please refer to [./examples/HunyuanVideo/](./examples/HunyuanVideo/) for more details.
+
+- **December 18, 2024** We propose ArtAug, an approach designed to improve text-to-image synthesis models through synthesis-understanding interactions. We have trained an ArtAug enhancement module for FLUX.1-dev in the format of LoRA. This model integrates the aesthetic understanding of Qwen2-VL-72B into FLUX.1-dev, leading to an improvement in the quality of generated images.

+
+- **October 25, 2024** We provide extensive FLUX ControlNet support. This project supports many different ControlNet models that can be freely combined, even if their structures differ. Additionally, ControlNet models are compatible with high-resolution refinement and partition control techniques, enabling very powerful controllable image generation. See [`./examples/ControlNet/`](./examples/ControlNet/).

-# 量化、卸载——显存优化的技术
-
-Flux.1 的发布让文生图开源社区再次活跃起来，但是其12B的参数量限制了显存低于24GB设备的运行。Diffsynth对Flux支持了量化（quantization）和卸载（offload）这两种优化显存的技术，降低了使用Flux的硬件设备门槛，本篇文章将介绍它们的原理和使用方式。
-
-
-## 量化
-
-模型量化指的是一种将高精度数据类型映射成低精度数据类型的技术，从而以损失少量精度为代价降低计算的时间和空间消耗。Flux.1 默认使用的数据类型为bfloat16，即每个参数占用16 bit（2 byte），我们使用torch支持的float8_e4m3fn加载模型，就能以更低的显存(节约10GB左右显存)消耗生成和原先几乎相同质量的图片。
-
-```python
-import torch
-from diffsynth import download_models, ModelManager, FluxImagePipeline
-
-download_models(["FLUX.1-dev"])
-
-model_manager = ModelManager(
-    torch_dtype=torch.bfloat16,
-)
-model_manager.load_models([
-    "models/FLUX/FLUX.1-dev/text_encoder/model.safetensors",
-    "models/FLUX/FLUX.1-dev/text_encoder_2",
-    "models/FLUX/FLUX.1-dev/ae.safetensors",
-])
-model_manager.load_models(
-    ["models/FLUX/FLUX.1-dev/flux1-dev.safetensors"],
-    torch_dtype=torch.float8_e4m3fn # Load the DiT model in FP8 format.
-)
-
-pipe = FluxImagePipeline.from_model_manager(model_manager, device="cuda")
-pipe.dit.quantize() 
-
-prompt = "CG, masterpiece, best quality, solo, long hair, wavy hair, silver hair, blue eyes, blue dress, medium breasts, dress, underwater, air bubble, floating hair, refraction, portrait. The girl's flowing silver hair shimmers with every color of the rainbow and cascades down, merging with the floating flora around her."
-negative_prompt = "worst quality, low quality, monochrome, zombie, interlocked fingers, Aissist, cleavage, nsfw,"
-
-torch.manual_seed(9)
-image = pipe(
-    prompt=prompt,
-    num_inference_steps=50, embedded_guidance=3.5
-)
-image.save("image_1024.jpg")
-```
-
-

-    <figure style="display: inline-block; margin-right: 20px;">
-        <img src="https://github.com/user-attachments/assets/d4c1699c-447b-4a5b-b453-4aa4d5ac066f" alt="图片1" width="300">

-        <figcaption>bfloat16</figcaption>
-    </figure>
-</div>
-<br>
-
-Diffsynth还支持ControlNet的量化，只需要在加载模型时指定数据类型为  ```torch.float8_e4m3fn```, 并且在生成图片前调用对应ControlNet模型的```quantize()```方法即可：
-```python
-model_manager.load_models(
-    ["models/ControlNet/jasperai/Flux.1-dev-Controlnet-Upscaler/diffusion_pytorch_model.safetensors"],
-    torch_dtype=torch.float8_e4m3fn 
-)
-pipe = FluxImagePipeline.from_model_manager(model_manager, controlnet_config_units=[
-    ControlNetConfigUnit(
-        processor_id="tile",
-        model_path="models/ControlNet/jasperai/Flux.1-dev-Controlnet-Upscaler/diffusion_pytorch_model.safetensors",
-        scale=0.7
-    ),
-],device="cuda")
-for model in pipe.controlnet.models:
-    model.quantize()
-```
-
-除了推理阶段，Diffsynth也支持在Lora训练阶段使用模型量化，只需要在训练参数中额外添加`--quantize "float8_e4m3fn"`。
-
-## 卸载
-
-模型卸载技术的思想很简单，只在需要模型进行计算的时候才将模型加载到GPU显存上，使用完毕后将模型卸载至CPU内存中，牺牲模型加载和卸载的时间换取显存消耗。除了本体外，文生图模型的pipeline通常还包括VAE、Text Encoder等模型，在生成图片时会依次调用它们。使用卸载技术可以将显存需求降低至它们之中最大的模型。
-Diffsynth支持对所有文生图模型使用卸载技术，要启用模型卸载，需要指定模型被加载至CPU上，pipeline运行在GPU上，再调用`enable_cpu_offload()`启用模型卸载，以Flux为例：
-
-```python
-model_manager = ModelManager(torch_dtype=torch.bfloat16, device="cpu") 
-model_manager.load_models([
-    "models/FLUX/FLUX.1-dev/text_encoder/model.safetensors",
-    "models/FLUX/FLUX.1-dev/text_encoder_2",
-    "models/FLUX/FLUX.1-dev/ae.safetensors",
-    "models/FLUX/FLUX.1-dev/flux1-dev.safetensors"
-])
-pipe = FluxImagePipeline.from_model_manager(model_manager,device="cuda")
-pipe.enable_cpu_offload()
-```
-
-## 总结
-
-模型量化和卸载都能有效降低显存消耗，并且互相兼容。模型卸载不会降低生成的图像质量，并且额外消耗的时间不多（受模型大小和设备通讯影响，通常每张图不超过3秒），因此在显存不足时优先推荐使用模型卸载。模型量化会损失部分图像质量，但在float8下质量差别不大。两种显存优化技术同时使用，可以将运行Flux的显存消耗从37GB降低至15GB。

-文生图模型 FLUX 发布之后，开源社区为其适配了用于控制生成内容的模型——ControlNet，DiffSynth-Studio 为这些模型提供了支持，我们支持任意多个 ControlNet 模型的组合调用，即使这些模型的结构不同。本篇文章将展示这些 ControlNet 模型的灵活用法。
-
-## Canny/Depth/Normal: 点对点结构控制
-
-结构控制是 ControlNet 模型最基础的能力，通过使用 Canny 提取出边缘信息，或者使用深度图和法线贴图，都可以用于表示图像的结构，进而作为图像生成过程中的控制信息。
-
-例如，我们生成一只猫猫，然后使用支持多控制条件的模型 InstantX/FLUX.1-dev-Controlnet-Union-alpha，同时启用 Canny 和 Depth 控制，让环境变为黄昏。

-ControlNet 对于结构的控制力度是可以调节的，例如在下面这里例子中，我们把小姐姐从夏天移动到冬天时，适当调低 ControlNet 的控制力度，模型就会根据画面内容作出调整，为小姐姐换上温暖的衣服。

-## Upscaler/Tile/Blur: 高清图像生成
-
-支持高清化的 ControlNet 模型有很多，例如
-
-模型链接: https://modelscope.cn/models/jasperai/Flux.1-dev-Controlnet-Upscaler, https://modelscope.cn/models/InstantX/FLUX.1-dev-Controlnet-Union-alpha, https://modelscope.cn/models/Shakker-Labs/FLUX.1-dev-ControlNet-Union-Pro
-
-这些模型可以把模糊的、含噪点的低质量图像处理成清晰的图像。在 DiffSynth-Studio 中，框架原生支持的高分辨率分块处理技术可以突破模型的分辨率限制，实现 2048 甚至更高分辨率的图像生成，进一步放大了这些模型的能力。在下面的例子中，我们可以看到高清放大到 2048 分辨率的图片中，猫猫的毛发纤毫毕现，人物的皮肤纹理精致逼真。

-## MultiControlNet+MultiDiffusion: 精细的高阶控制
-
-DiffSynth-Studio 不仅支持多个不同结构的 ControlNet 同时生效，还支持使用不同提示词分区控制图中内容，还支持超高分辨率大图的分块处理，这让我们能够作出极为精细的高阶控制。接下来，我们展示一张精美图片的创作过程。
-
-首先使用提示词“a beautiful Asian woman and a cat on a bed. The woman wears a dress”生成一只猫猫和一位少女。
-
-![image_13](https://github.com/user-attachments/assets/8da006e4-0e68-4fa5-b407-31ef5dbe8e5a)

-分两个区域进行控制：
-
-|Prompt: an orange cat, highly detailed|Prompt: a girl wearing a red camisole|
-|:-:|:-:|
-|![mask_13_1](https://github.com/user-attachments/assets/188530a0-913c-48db-a7f1-62f0384bfdc3)|![mask_13_2](https://github.com/user-attachments/assets/99c4d0d5-8cc3-47a0-8e56-ceb37db4dfdc)|

-# 翻译、润色——提示词的魔法
-
-在生成图像时，我们需要编写提示词，用来描述图像的内容。提示词会直接影响生成的效果，但提示词的编写也是一门学问，好的提示词可以生成具有高度美感的图像，我们提供了一系列模型来帮助用户处理提示词。
-
-## 翻译
-
-目前大多数文生图模型都是只支持英文提示词的，对于非英文母语的用户，使用起来有些困难，我们可以使用开源的翻译模型把提示词翻译成英文。在下面这个例子中，我们以“一个女孩”为提示词，使用模型 opus-mt-zh-en（可在 [HuggingFace](https://huggingface.co/Helsinki-NLP/opus-mt-zh-en) 或 [ModelScope](https://modelscope.cn/models/moxying/opus-mt-zh-en) 下载）进行翻译。
-
-```python
-from diffsynth import ModelManager, SDXLImagePipeline, Translator
-import torch
-
-model_manager = ModelManager(
-    torch_dtype=torch.float16, device="cuda",
-    model_id_list=["BluePencilXL_v200", "opus-mt-zh-en"]
-)
-pipe = SDXLImagePipeline.from_model_manager(model_manager, prompt_refiner_classes=[Translator])
-
-torch.manual_seed(0)
-prompt = "一个女孩"
-image = pipe(
-    prompt=prompt, negative_prompt="",
-    height=1024, width=1024, num_inference_steps=30
-)
-image.save("image_1.jpg")
-```
-
-![image_1](https://github.com/user-attachments/assets/c8070a6b-3d2f-4faf-a806-c403b91f1a94)
-
-## 润色
-
-详细的提示词可以生成细节更丰富的图像，我们可以使用提示词润色模型 BeautifulPrompt（可在 [HuggingFace](https://huggingface.co/alibaba-pai/pai-bloom-1b1-text2prompt-sd) 或 [ModelScope](https://modelscope.cn/models/AI-ModelScope/pai-bloom-1b1-text2prompt-sd) 下载）对简单的提示词进行润色，这个模型能够让整体画面风格更加华丽。
-
-这个模块可以和翻译模块同时启用，但请注意顺序，先翻译，后润色。
-
-```python
-from diffsynth import ModelManager, SDXLImagePipeline, Translator, BeautifulPrompt
-import torch
-
-model_manager = ModelManager(
-    torch_dtype=torch.float16, device="cuda",
-    model_id_list=["BluePencilXL_v200", "opus-mt-zh-en", "BeautifulPrompt"]
-)
-pipe = SDXLImagePipeline.from_model_manager(model_manager, prompt_refiner_classes=[Translator, BeautifulPrompt])
-
-torch.manual_seed(0)
-prompt = "一个女孩"
-image = pipe(
-    prompt=prompt, negative_prompt="",
-    height=1024, width=1024, num_inference_steps=30
-)
-image.save("image_2.jpg")
-```
-
-![image_2](https://github.com/user-attachments/assets/94f64a7d-b14a-41e2-a013-c9a74635a84d)
-
-我们还内置了一个通义千问模型，这个模型可以一步到位地完成提示词的翻译和润色工作。
-
-```python
-from diffsynth import ModelManager, SDXLImagePipeline, QwenPrompt
-import torch
-
-model_manager = ModelManager(
-    torch_dtype=torch.float16, device="cuda",

-)
-pipe = SDXLImagePipeline.from_model_manager(model_manager, prompt_refiner_classes=[QwenPrompt])

-# 当图像模型遇见 AnimateDiff——模型组合技术
-
-我们已经领略到了 Stable Diffusion 模型及其生态模型的强大图像生成能力，现在我们引入一个新的模块：AnimateDiff，这样一来就可以把图像模型的能力迁移到视频中。在本篇文章中，我们为您展示基于 DiffSynth-Studio 搭建的动漫风格视频渲染方案：Diffutoon。
-
-## 下载模型
-
-接下来的例子会用到很多模型，我们先把它们下载好。
-
-* 一个动漫风格的 Stable Diffusion 架构模型
-* 两个 ControlNet 模型
-* 一个 Textual Inversion 模型
-* 一个 AnimateDiff 模型
-
-```python
-from diffsynth import download_models
-
-download_models([
-    "AingDiffusion_v12",
-    "AnimateDiff_v2",
-    "ControlNet_v11p_sd15_lineart",
-    "ControlNet_v11f1e_sd15_tile",
-    "TextualInversion_VeryBadImageNegative_v1.3"
-])
-```
-
-## 下载视频
-
-你可以随意选择任何你喜欢的视频，我们使用[这个视频](https://www.bilibili.com/video/BV1iG411a7sQ)作为演示，你可以通过以下命令下载这个视频文件，但请注意，在没有获得视频原作者的商用版权时，请不要将其用作商业用途。

-# 训练框架
-
-我们实现了一个用于文本到图像扩散模型的训练框架，使用户能够轻松地使用我们的框架训练 LoRA 模型。我们提供的脚本具有以下特点：
-
-* **功能全面**：我们的训练框架支持多GPU和多机器配置，便于使用 DeepSpeed 加速，并包括梯度检查点优化，适用于内存需求较大的模型。
-* **代码简洁**：我们避免了大块复杂的代码。通用模块实现于 `diffsynth/trainers/text_to_image.py` 中，而模型特定的训练脚本仅包含与模型架构相关的最少代码，便于学术研究人员使用。
-* **模块化设计**：基于通用的 Pytorch-Lightning 框架，我们的训练框架在功能上是解耦的，允许开发者通过修改我们的脚本轻松引入额外的训练技术，以满足他们的需求。
-
-LoRA 微调的图像示例。提示词为 "一只小狗蹦蹦跳跳，周围是姹紫嫣红的鲜花，远处是山脉"（针对中文模型）或 "a dog is jumping, flowers around the dog, the background is mountains and clouds"（针对英文模型）。

-## 安装额外包
-
-```
-pip install peft lightning
-```
-
-## 准备数据集
-
-我们提供了一个[示例数据集](https://modelscope.cn/datasets/buptwq/lora-stable-diffusion-finetune/files)。你需要将训练数据集按照如下形式组织：
-
-```
-data/dog/
-└── train
-    ├── 00.jpg
-    ├── 01.jpg
-    ├── 02.jpg
-    ├── 03.jpg
-    ├── 04.jpg
-    └── metadata.csv
-```
-
-`metadata.csv`:
-
-```
-file_name,text
-00.jpg,a dog
-01.jpg,a dog
-02.jpg,a dog
-03.jpg,a dog
-04.jpg,a dog
-```
-
-请注意，如果模型是中文模型（例如，Hunyuan-DiT 和 Kolors），我们建议在数据集中使用中文文本。例如：
-
-```
-file_name,text
-00.jpg,一只小狗
-01.jpg,一只小狗
-02.jpg,一只小狗
-03.jpg,一只小狗
-04.jpg,一只小狗
-```

-## 模型介绍
-
-AnimateDiff 是一种文生图模型的扩展方法，可以将文生图模型扩展为动画生成器，而无需对文生图模型做任何微调。扩展的基本思路是从大型视频数据集中学习到运动先验知识并保存到运动模块中，使用时将运动模块插入文生图模型即可。以下为其生成的视频效果：

-</video>
-</div>
-
-
-AnnimateDiff 的训练主要分为三个阶段，分别对应了三个可训练的模块：Domain Adapter，Motion Module 和 MotionLoRA，如下图所示。
-
-![](https://github.com/user-attachments/assets/a788caf8-9cc8-45bb-ba20-d80684d80e08)
-
-第一阶段中主要训练 Domain Adapter。由于公开可用的视频训练数据集的质量远低于图像数据集的质量，直接从这种数据集上训练 Motion Module 可能就降低其视频生成质量。视频和图像数据集质量的差距被成为域差距。为了减小这一差距对 Motion Module 的影响，作者提出使用 Domain Adapter 来单独拟合这些域差距。Domain Adapter 具体通过LoRA来实现，即在文生图模型中的 Self/Cross-Attention 层中插入 LoRA 模块。以 Query Projection 为例，插入 LoRA 后的输出如下公式所示。其中，$\alpha$ 为 Domain Adapter 权重。在推理的时候，设置 $\alpha=0$ 以去除 Domain Adapter 的影响。
-
-$$
-Q=\mathcal{W}^Q z+\text { AdapterLayer }(z)=\mathcal{W}^Q z+\alpha \cdot A B^T z
-$$
-
-第二阶段主要训练 Motion Module，这一模块主要目的是学习视频的运动先验信息。如上图所示， Motion Module 主要结构为 Temporal Transformer，由输入输出映射层和若干个 Self-Attention 组成。将 Motion Module 插入文生图模型后，模型的输入维度为：$b\times c\times f \times h \times w$。在数据到达文生图模型的原始模块（上图白色）时，将帧数 $f$ 融合到 $b$ 维度上，即可完成正常计算。当数据到达 Motion Module 时，为了完成 Temporal Attention，又将 $h$ 和 $w$ 融合到 $b$ 维度上，数据维度变为： $\{b\cdot h\cdot w\} \times f \times c$。
-
-尽管第二阶段训练的 Motion Module 学习了通用的运动先验知识，但仍然需要有效地将其适应到特定运动模式，比如相机缩放、平移等。因此，第三阶段主要针对个性化运动训练对应的 MotionLoRA。MotionLoRA 主要是通过在 Motion Module 的 Attention 中加入LoRA中实现的。实验证明，20 ~ 50 个参考视频、2000 个 step 就能学习到对应的运动能力。同时，多个 MotionLoRA 的运动效果是可以组合的。

-## 模型介绍
-ControlNet 是一种辅助性的模型架构，它能够与已经训练好的 Diffusion 模型相结合。通过给模型额外添加可训练的 ControlNet 模块，我们得以在图像生成过程中施加额外的控制条件。比如，我们可以加入深度图、语义图和人体关键点等额外条件，控制生成图像的画面结构和布局。值得注意的是，针对不同的 Diffusion 模型， ControlNet 的具体结构可能会有所差异。
-
-### ControlNet-V11-SD15
-ControlNet V1.1 是基于 Stable Diffusion V1.5 (SD15) 的 ControlNet 更新版本，包含 Canny, Depth, Segmentation, Inpaint, Lineart 等控制条件对应的模型。
-
-ControlNet 原论文是针对 SD15 设计的模型结构，如下图所示。(a) 部分结构为已训练完成的 Stable Diffusion (SD) 模型，模型输入为文本 Prompt $c_t$ 与去噪时间步长 $t$。(b) 部分结构为 ControlNet，主要包括若干个零初始化的卷积层 (zero convolution) 和 SD UNet Encoder 的可训练副本，模型输入为额外的控制条件 $c_f$。
-
-zero convolution 为 $1\times1$ 的卷积层，其权重和偏置都被初始化为0。因此，在 ControlNet 被训练之前，所有 zero convolution 模块的输出都为0，保证了 ControlNet 的输出也为0，从而不会改变 SD 模型的输出。注意，zero convolution 的权重和偏置初始化为0并不会导致其梯度也为0，因此这些卷积层是能被训练的。
-
-ControlNet 中的可训练副本采用与 SD UNet Encoder Blocks 相同的结构，并以其与训练好的权重作为初始化。而 SD 模型本身的所有参数都处于冻结状态。在训练过程中，只有 ControlNet 的参数会进行更新。因此，我们既能通过 ControlNet 的对额外的控制条件进行学习训练，又不会破坏 SD 模型本身的能力。
-
-给定 SD 模型参数 $\Theta$， ControlNet 参数 $\Theta_{\mathrm{c}}$， 两个 zero convolution 模块 $\Theta_{\mathrm{z1}}$ 和 $\Theta_{\mathrm{z2}}$， 模型的输出如下。
-
-$$
-\boldsymbol{y}_{\mathrm{c}}=\mathcal{F}(\boldsymbol{x} ; \Theta)+\mathcal{Z}\left(\mathcal{F}\left(\boldsymbol{x}+\mathcal{Z}\left(\boldsymbol{c} ; \Theta_{\mathrm{z} 1}\right) ; \Theta_{\mathrm{c}}\right) ; \Theta_{\mathrm{z2}}\right)
-$$

-ControlNet 生成图像示例如下所示：
-![](https://github.com/user-attachments/assets/b0a122b7-2610-465e-9d01-6237c3fbe0f0)
-
-## ControlNet++
-ControlNet++ 是针对 Stable Diffusion XL (SDXL) 模型设计的 ControlNet 结构，对应上文提到的 ControlNet-Union-SDXL 模型。这一模型能同时支持10多种控制条件，包括 Pose，Depth，Canny，Lineart 等。
-
-模型结构如下图所示。相比于 ControlNet ，这一模型扩充了 Condition Encoder 的卷积通道数量，同时增加了两个新模块，分别是 Condition Transformer 和 Control Encoder。Condition Transformer 用于组合不同的图像条件特征，而 Control Encoder 则用于编码控制条件的类型。

-## 模型介绍
-
-ExVideo 是一种视频生成模型的后训练（post-training）方法，旨在增强视频生成模型的能力，使其能够生成更长的视频。目前，ExVideo 已经发布了两个版本，分别将 Stable Video Diffusion 扩展到 128 帧、将 CogVideoX-5B 扩展到 129 帧。
-
-在基于 Stable Video Diffusion 的 ExVideo 扩展模块中，静态的位置编码被替换为了可训练的参数矩阵，并在时序模块中添加了额外的单位卷积（Identidy 3D Convolution），在保留预训练模型本身能力的前提下，使其能够捕获更长时间尺度上的信息，从而生成更长视频。而在基于 CogVideoX-5B 的 ExVideo 扩展模块中，由于模型基础架构为 DiT，为保证计算效率，扩展模块采用 LoRA 的形式构建。
-
-![](https://github.com/user-attachments/assets/94aa31ba-3ee3-4421-9713-83333a165660)
-
-为了在有限的计算资源上实现长视频的训练，ExVideo 做了很多工程优化，包括：
-
-* Parameter freezing：冻结除了扩展模块以外的所有参数
-* Mixed precision：扩展模块部分以全精度维护，其他部分以 BFloat16 精度维护
-* Gradient checkpointing：在前向传播时丢弃中间变量，并反向传播时重新计算
-* Flash attention：在所有注意力机制上启用加速过的注意力实现
-* Shard optimizer states and gradients：基于 DeepSpeed 把部分参数分拆到多个 GPU 上

-## 模型介绍
-
-FLUX.1  是由 The Black Forest Team 发布的一系列文生图模型，该模型在图像细节、提示一致性、风格多样性和文本到图像合成的场景复杂性方面定义了新的最先进技术。FLUX.1 提供了三个变体：FLUX.1 [pro]、FLUX.1 [dev] 和 FLUX.1 [schnell]，我们在这里用到的是从 FLUX.1 [pro] 蒸馏出来的用于非商业应用的开放权重的 FLUX.1 [dev]。
-FLUX.1 模型均基于多模态和并行扩散变压器块的混合架构，并可缩放至 12B 参数。通过建立流匹配来改进以前最先进的扩散模型，流匹配是一种通用且概念上简单的训练生成模型的方法，其中包括作为特殊情况的扩散。此外，通过结合旋转位置嵌入和并行注意层来提高模型性能并提高硬件效率。
-
-FLUX.1 定义了图像合成领域的最新技术，FLUX.1 [pro] 和 [dev] 在以下各个方面超越了 Midjourney v6.0、DALL·E 3 (HD) 和 SD3-Ultra 等流行模型：视觉质量、提示跟随、尺寸/方面可变性、版式和输出多样性。 FLUX.1 [schnell] 是迄今为止最先进的几步模型，其性能不仅优于同类竞争对手，而且还优于 Midjourney v6.0 和 DALL·E 3 (HD) 等强大的非蒸馏模型。FLUX.1 经过专门微调，以保留预训练的整个输出多样性。与当前最先进的技术相比，它们提供了极大改进的可能性，如下所示：

Hunyuan-DiT接受VAE潜在空间的向量作为输入, 将它分割成小块后经过线性层得到后续用于transformer块的标记. 在每个Hunyuan-DiT Block中包含三个模块, 自注意力(self-attention), 交叉注意力(cross-attention), 和前馈网络(feed-forward network, FFN).

-## 模型介绍
-
-IP-Adapter 与 ControlNet 技术类似，是一种通过添加辅助性模型架构，为模型添加额外的控制条件的方法。与 ControlNet 类似的是，IP-Adapter 的额外控制条件也是图像输入，不同的是，IP-Adapter 的额外控制条件是通过 Cross-Attention 的方式加入到原始模型中的。
-
-IP-Adapter 模型结构如下图所示。不考虑最上层的图像控制条件时，文本特征的信息通过 Cross-Attention 结构被加入到 Denoising U-Net 中，这就是典型的文生图 Pipeline。IP-Adapter 参考这一条件控制的范式，加入了图像控制条件。 对于一个控制图像，首先使用 Image Encoder 提取图像特征，然后使用投影网络将其映射为一个长度为 $N$ 的特征序列。在这个时候，图像特征与文本特征的特征形式已经相近，作者便使用同样的 Cross-Attention 结构来融合这一图像特征到 U-Net 中。 Image Encoder 采用经过预训练的 CLIP 模型，投影网络由一个线性层和层归一化组成，投影后的图像特征序列长度取 $N=4$。
-
-![](https://github.com/user-attachments/assets/5ebe45a4-6877-41fe-a2e5-deb2ea33dfdb)
-
-
-为了不破坏文生图基础模型的文本控制能力，IP-Adapter 采用了文图解耦的 Cross-Attention 结构，即冻结原本的文本 Cross-Attention，加入额外的图像 Cross-Attention 结构。解耦的 Cross-Attention 公式如下所示，其中 $K$ 和 $V$ 是文本的 Key 和 Value 向量， $K^{\prime}$ 和 $V^{\prime}$ 是图像的 Key 和 Value 向量。由于两个 Attention 的 Query 向量是一样的，只需要添加两个映射矩阵 $W_{K^{\prime}}$ 和 $W_{V^{\prime}}$ 作为可学习参数，这两个参数分别从 $W_{K}$ 和 $W_{V}$ 初始化而来。
-
-$$
-\mathbf{Z}^{\text {new }}=\operatorname{Softmax}\left(\frac{\mathbf{Q} \mathbf{K}^{\top}}{\sqrt{d}}\right) \mathbf{V}+\operatorname{Softmax}\left(\frac{\mathbf{Q}\left(\mathbf{K}^{\prime}\right)^{\top}}{\sqrt{d}}\right) \mathbf{V}^{\prime}
-$$
-
-综上所述，IP-Adapter 只有投影网络和部分 Cross-Attenion 参数是可学习的，一共只有 22M 可学习参数量。

-
-## 模型介绍
-
-Stable Diffusion 是一种基于扩散模型的文本到图像生成技术，它最初由 [Stability AI](https://stability.ai/) 和 [LAION](https://laion.ai/) 基于 [LAION-5B](https://laion.ai/blog/laion-5b/) 的子集，对 512*512 的图像训练了一个 latent diffusion model，使用 CLIP ViT-L/14 文本编码器编码文本作为模型的提示。
-
-扩散模型（DMs）在图像数据及其他领域达到了最先进的合成效果，但是由于直接在像素空间进行加噪和去噪过程，训练和推理时需要大量计算资源，为了在有限的计算资源下训练扩散模型，同时保留其质量和灵活性，Stable Diffusion 在预训练自动编码器的潜在空间 (Latent Space) 中训练扩散模型。
-
-与之前的工作相比，在这种在潜空间表示上训练扩散模型达到了低复杂性和空间下采样之间的近乎最佳平衡，大大提升了视觉保真度。通过将交叉注意力层引入模型架构，扩散模型被转变为功能强大的灵活生成器，可以用于文本或边界框等一般条件输入，并通过卷积方式实现高分辨率合成。
-
-Stable Diffusion 在各种任务上表现出极具竞争力的性能，包括无条件图像生成、图像修复和超分辨率，同时相较于基于像素的扩散模型显著降低了计算需求。
-
-Stable Diffusion 的模型结构如下图所示，通过交叉注意力来实现条件控制。

-## 模型介绍
-
-Stable Diffusion 3（SD3）是 Stability AI 的文生图开源模型，在基于人类偏好的评估中，Stable Diffusion 3 在文字生成图像的性能上超过了目前最先进的系统，包括 DALL·E 3、Midjourney v6 和 Ideogram v1，并在文字内容生成，复杂提示理解和指令遵循方面的性能有显著提升。SD3 采用了全新的多模态扩散变压器（MMDiT）架构，使用不同的权重集来处理图像和语言表示，提高了模型的文本理解和拼写能力。
-
-最大的 SD3 模型拥有 80 亿参数，可以装入拥有 24GB VRAM 的 RTX 4090 中，使用 50 次采样步骤生成一张 1024x1024 分辨率的图像仅需 34 秒。此外，还发布了多种版本的，参数范围从8亿到80亿的 Stable Diffusion 3。
-
-![image](https://github.com/user-attachments/assets/e6d95a9e-cd0a-4438-a564-0754eb4c10e1)
-
-MMDiT 架构使用三种不同的文本嵌入器（两个 CLIP 模型和 T5）来编码文本表示，并使用改进的自动编码模型来编码图像，然后将结合两种模态的序列拼接起来尽进行注意力操作。相比传统的文本生成图像网络，这种架构在视觉保真度和文本对齐度的训练过程中表现更佳。通过该方法，信息可以在图像和文本之间流动，进而提高生成内容的整体理解能力和视觉设计，同时其设计也容易扩展到视频等多种模态的应用。
-
-此外，SD3 引入了改进的校正流（RF）公式，使得在训练过程中，数据和噪声可以沿着更直的线性轨迹连接，从而减少了采样步骤。通过对采样计划的重加权，尤其是在中间部分，提升了模型的预测任务性能。与其他 60 种扩散轨迹（例如LDM 、 EDM 和 ADM ））相比，重加权的RF变体在性能上具有更优越的表现。
-
-在文本编码方面，尽管在推理过程中将拥有 4.7B 参数的 T5 文本编码器排除在外减少了内存需求并略微影响性能，但这对视觉美学无大影响，只是稍微降低了提示文本的遵循性。为了充分发挥文本生成能力，尤其是在处理复杂提示文本的场景中，建议保留 T5 文本编码器。

-
-## 模型介绍
-
-Stable Video Diffusion 模型是 StabilityAI 训练并开源的图生视频模型，该模型与 Stable Diffusion 模型类似，采用三段式的模型架构。
-
-* Image Encoder 采用了 CLIP 模型中的 ViT 部分，用于将输入的图像转化为 Embedding。
-* VAE 分为 Encoder 和 Decoder 部分，Encoder 部分与 Stable Diffusion v1.x 完全相同，仅在图像层面对视频进行逐帧压缩；Decoder 部分在 Stable Diffusion v1.x VAE Decoder 的基础上增加了 3D 的卷积层并进一步进行了训练，用于消除逐帧处理过程中的闪烁问题。
-* UNet 部分同时将 Image Encoder 和 VAE Encoder 的输出作为输入，用于在 Latent Space 中进行迭代去噪。
-
-Stable Video Diffusion 模型可以把输入的图像作为视频第一帧，并生成后续的 24 帧。但值得注意的是，虽然理论上可以继续分段生成更长视频，但分段之间缺乏连续性，因此我们不建议用这个模型分段生成较长视频。

-# 快速开始
-
-在这篇文档中，我们通过一段代码为你介绍如何快速上手使用 DiffSynth-Studio 进行创作。
-
-## 安装
-
-使用以下命令从 GitHub 克隆并安装 DiffSynth-Studio。更多信息请参考[安装](./Installation.md)。
-
-```shell
-git clone https://github.com/modelscope/DiffSynth-Studio.git
-cd DiffSynth-Studio
-pip install -e .
-```
-
-## 一键运行！
-
-通过运行以下代码，我们将会下载模型、加载模型、生成图像。
-
-```python
-from diffsynth import ModelManager, SDXLImagePipeline
-
-model_manager = ModelManager(device="cuda", model_id_list=["StableDiffusionXL_v1"])
-pipe = SDXLImagePipeline.from_model_manager(model_manager)
-
-image = pipe(
-    prompt="Diffuse light particles in the universe",
-    height=576, width=1024, seed=0
-)
-image.save("image.jpg")
-```
-
-![image](https://github.com/user-attachments/assets/2e60d18e-534c-43d6-b875-26db5b05442e)
-
-从这个例子中，我们可以看到，DiffSynth 中有两个关键模块：`ModelManager` 和 `Pipeline`，接下来我们详细介绍。
-
-## 下载和加载模型
-
-`ModelManager` 负责下载和加载模型，通过以下代码可以直接一步完成。
-
-```python
-from diffsynth import ModelManager, SDXLImagePipeline
-
-model_manager = ModelManager(device="cuda", model_id_list=["StableDiffusionXL_v1"])
-```
-
-当然，我们也支持分步完成，以下代码和上述代码的行为是等价的。
-
-```python
-from diffsynth import download_models, ModelManager
-
-download_models(["StableDiffusionXL_v1"])
-model_manager = ModelManager(device="cuda")
-model_manager.load_models(["models/stable_diffusion_xl/sd_xl_base_1.0.safetensors"])
-```
-
-下载模型时，我们支持从 [ModelScope](https://www.modelscope.cn/) 和 [HuggingFace](https://huggingface.co/) 下载模型，也支持下载非预置的模型，关于模型下载的更多信息请参考[模型下载](./DownloadModels.md)。
-
-加载模型时，你可以把所有想要加载的模型路径放入其中。对于 `.safetensors` 等格式的模型权重文件，`ModelManager` 在加载后会自动判断模型类型；对于文件夹格式的模型，`ModelManager` 会尝试解析其中的 `config.json` 文件并尝试调用 `transformers` 等第三方库中的对应模块。关于 DiffSynth-Studio 支持的模型，请参考[支持的模型](./Models.md)。
-
-## 构建 Pipeline
-
-DiffSynth-Studio 提供了多个推理 `Pipeline`，这些 `Pipeline` 可以直接通过 `ModelManager` 获取所需的模型并初始化。例如，Kolors（可图）模型的文生图 `Pipeline` 可以这样构建：
-
-```python
-pipe = SDXLImagePipeline.from_model_manager(model_manager)
-```
-
-更多用于图像生成和视频生成的 `Pipeline` 详见[推理流水线](./Pipelines.md)。

-
-## 下载非预置模型
-
-你可以选择 [ModelScope](https://modelscope.cn/models) 和 [HuggingFace](https://huggingface.co/models) 两个下载源中的模型。当然，你也可以通过浏览器等工具选择手动下载自己所需的模型。
-
-```python
-from diffsynth import download_customized_models

-download_customized_models(
-    model_id="Kwai-Kolors/Kolors",
-    origin_file_path="vae/diffusion_pytorch_model.fp16.bin",
-    local_dir="models/kolors/Kolors/vae",
-    downloading_priority=["ModelScope", "HuggingFace"]
-)
-```
-
-在这段代码中，我们将会按照下载的优先级，优先从 `ModelScope` 下载，在 ID 为 `Kwai-Kolors/Kolors` 的[模型库](https://modelscope.cn/models/Kwai-Kolors/Kolors)中，把文件 `vae/diffusion_pytorch_model.fp16.bin` 下载到本地的路径 `models/kolors/Kolors/vae` 中。

-# 调度器
-
-调度器（Scheduler）控制模型的整个去噪（或采样）过程。在加载 Pipeline 时，DiffSynth 会自动选择最适合当前 Pipeline 的调度器，**无需额外配置**。
-
-我们支持的调度器包括：
-
-- **EnhancedDDIMScheduler**：扩展了去噪扩散概率模型（DDPM）中的去噪过程，引入了非马尔可夫指导。
-
-- **FlowMatchScheduler**：实现了 [Stable Diffusion 3](https://arxiv.org/abs/2403.03206) 中提出的流量匹配采样方法。
-
-- **ContinuousODEScheduler**：基于常微分方程（ODE）的调度器。

-# ControlNet、LoRA、IP-Adapter——Precision Control Technology
-
-Based on the text-to-images model, various adapter-based models can be used to control the generation process.
-
-Let's download the models we'll be using in the upcoming examples:
-
-* A highly praised Stable Diffusion XL architecture anime-style model
-* A ControlNet model that supports multiple control modes
-* A LoRA model for the Stable Diffusion XL model
-* An IP-Adapter model and its corresponding image encoder
-
-Please note that the names of the models are kept in English as per your instruction to retain specific terminology.

-Isn't that cool? There's more! Add a LoRA to make the image closer to the flat style of hand-drawn comics. This LoRA requires certain trigger words to take effect, which is mentioned on the original author's model page. Remember to add the trigger words at the beginning of the prompt.

-Use the image-to-image feature to turn her hair red, simply by adding `input_image` and `denoising_strength` as parameters. The `denoising_strength` controls the intensity of the noise added, when set to 0, the generated image will be identical to the input image, and when set to 1, it will be completely randomly generated.
-
-```python
-torch.manual_seed(1)
-image_edited = pipe(

-
-Since the model itself was trained at a resolution of 512*512, the image appears a bit blurry. However, we can utilize the model's own capabilities to refine the image and add details. Specifically, this involves increasing the resolution and then using image-to-image generation.
-```python
-torch.manual_seed(2)
-image_highres = pipe(
-    prompt="masterpiece, best quality, a girl with long red hair",
-    negative_prompt="worst quality, low quality, monochrome, zombie, interlocked fingers, Aissist, cleavage, nsfw,",

-It's worth noting that the image-to-image and high-resolution restoration features are globally supported, and currently, all of our image generation pipelines can be used in this way.
