 ## 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!
 
-## Roadmap
+Until now, DiffSynth Studio has supported the following models:
+
+* [ExVideo](https://huggingface.co/ECNU-CILab/ExVideo-SVD-128f-v1)
+* [Kolors](https://huggingface.co/Kwai-Kolors/Kolors)
+* [Stable Diffusion 3](https://huggingface.co/stabilityai/stable-diffusion-3-medium)
+* [Stable Video Diffusion](https://huggingface.co/stabilityai/stable-video-diffusion-img2vid-xt)
+* [Hunyuan-DiT](https://github.com/Tencent/HunyuanDiT)
+* [RIFE](https://github.com/hzwer/ECCV2022-RIFE)
+* [ESRGAN](https://github.com/xinntao/ESRGAN)
+* [Ip-Adapter](https://github.com/tencent-ailab/IP-Adapter)
+* [AnimateDiff](https://github.com/guoyww/animatediff/)
+* [ControlNet](https://github.com/lllyasviel/ControlNet)
+* [Stable Diffusion XL](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0)

+## News
+
+
+- **June 21, 2024.** 🔥🔥🔥 We propose ExVideo, a post-tuning technique aimed at enhancing the capability of video generation models. We have extended Stable Video Diffusion to achieve the generation of long videos up to 128 frames.
+  - [Project Page](https://ecnu-cilab.github.io/ExVideoProjectPage/)
+  - Source code is released in this repo. See [`examples/ExVideo`](./examples/ExVideo/).
+  - Models are released on [HuggingFace](https://huggingface.co/ECNU-CILab/ExVideo-SVD-128f-v1) and [ModelScope](https://modelscope.cn/models/ECNU-CILab/ExVideo-SVD-128f-v1).
+  - Technical report is released on [arXiv](https://arxiv.org/abs/2406.14130).
+  - You can try ExVideo in this [Demo](https://huggingface.co/spaces/modelscope/ExVideo-SVD-128f-v1)!
+
+- **June 13, 2024.** DiffSynth Studio is transferred to ModelScope. The developers have transitioned from "I" to "we". Of course, I will still participate in development and maintenance.

+  - [Project Page](https://ecnu-cilab.github.io/DiffutoonProjectPage/)
+  - The source codes are released in this project.
+  - The technical report (IJCAI 2024) is released on [arXiv](https://arxiv.org/abs/2401.16224).
+
+- **Dec 8, 2023.** We decide to develop a new Project, aiming to release the potential of diffusion models, especially in video synthesis. The development of this project is started.
+
+- **Nov 15, 2023.** We propose FastBlend, a powerful video deflickering algorithm.

+  - The technical report is released on [arXiv](https://arxiv.org/abs/2311.09265).
+  - An unofficial ComfyUI extension developed by other users is released on [GitHub](https://github.com/AInseven/ComfyUI-fastblend).
+
+- **Oct 1, 2023.** We release an early version of this project, namely FastSDXL. A try for building a diffusion engine.
+  - The source codes are released on [GitHub](https://github.com/Artiprocher/FastSDXL).
