+
+
+**November 21, 2023**
+- We are releasing Stable Video Diffusion, an image-to-video model, for research purposes:
+    - [SVD](https://huggingface.co/stabilityai/stable-video-diffusion-img2vid): This model was trained to generate 14
+      frames at resolution 576x1024 given a context frame of the same size.
+      We use the standard image encoder from SD 2.1, but replace the decoder with a temporally-aware `deflickering decoder`.
+    - [SVD-XT](https://huggingface.co/stabilityai/stable-video-diffusion-img2vid-xt): Same architecture as `SVD` but finetuned
+      for 25 frame generation.
+    - We provide a streamlit demo `scripts/demo/video_sampling.py` and a standalone python script `scripts/sampling/simple_video_sample.py` for inference of both models.
+    - Alongside the model, we release a [technical report](https://stability.ai/research/stable-video-diffusion-scaling-latent-video-diffusion-models-to-large-datasets).
+
+  ![tile](assets/tile.gif)
+
+**July 26, 2023**
+
+- We are releasing two new open models with a
+  permissive [`CreativeML Open RAIL++-M` license](model_licenses/LICENSE-SDXL1.0) (see [Inference](#inference) for file
+  hashes):
+    - [SDXL-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0): An improved version
+      over `SDXL-base-0.9`.
+    - [SDXL-refiner-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0): An improved version
+      over `SDXL-refiner-0.9`.
+
+![sample2](assets/001_with_eval.png)
+
+**July 4, 2023**
+
+- A technical report on SDXL is now available [here](https://arxiv.org/abs/2307.01952).
+
+**June 22, 2023**
+
+- We are releasing two new diffusion models for research purposes:
+    - `SDXL-base-0.9`: The base model was trained on a variety of aspect ratios on images with resolution 1024^2. The
+      base model uses [OpenCLIP-ViT/G](https://github.com/mlfoundations/open_clip)
+      and [CLIP-ViT/L](https://github.com/openai/CLIP/tree/main) for text encoding whereas the refiner model only uses
+      the OpenCLIP model.
+    - `SDXL-refiner-0.9`: The refiner has been trained to denoise small noise levels of high quality data and as such is
+      not expected to work as a text-to-image model; instead, it should only be used as an image-to-image model.
+
+If you would like to access these models for your research, please apply using one of the following links:
+[SDXL-0.9-Base model](https://huggingface.co/stabilityai/stable-diffusion-xl-base-0.9),
+and [SDXL-0.9-Refiner](https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-0.9).
+This means that you can apply for any of the two links - and if you are granted - you can access both.
+Please log in to your Hugging Face Account with your organization email to request access.
+**We plan to do a full release soon (July).**
+
+## The codebase
+
+### General Philosophy
+
+Modularity is king. This repo implements a config-driven approach where we build and combine submodules by
+calling `instantiate_from_config()` on objects defined in yaml configs. See `configs/` for many examples.
+
+### Changelog from the old `ldm` codebase
+
+For training, we use [PyTorch Lightning](https://lightning.ai/docs/pytorch/stable/), but it should be easy to use other
+training wrappers around the base modules. The core diffusion model class (formerly `LatentDiffusion`,
+now `DiffusionEngine`) has been cleaned up:
+
+- No more extensive subclassing! We now handle all types of conditioning inputs (vectors, sequences and spatial
+  conditionings, and all combinations thereof) in a single class: `GeneralConditioner`,
+  see `sgm/modules/encoders/modules.py`.
+- We separate guiders (such as classifier-free guidance, see `sgm/modules/diffusionmodules/guiders.py`) from the
+  samplers (`sgm/modules/diffusionmodules/sampling.py`), and the samplers are independent of the model.
+- We adopt the ["denoiser framework"](https://arxiv.org/abs/2206.00364) for both training and inference (most notable
+  change is probably now the option to train continuous time models):
+    * Discrete times models (denoisers) are simply a special case of continuous time models (denoisers);
+      see `sgm/modules/diffusionmodules/denoiser.py`.
+    * The following features are now independent: weighting of the diffusion loss
+      function (`sgm/modules/diffusionmodules/denoiser_weighting.py`), preconditioning of the
+      network (`sgm/modules/diffusionmodules/denoiser_scaling.py`), and sampling of noise levels during
+      training (`sgm/modules/diffusionmodules/sigma_sampling.py`).
+- Autoencoding models have also been cleaned up.
+
+## Installation:
+
+<a name="installation"></a>
+
+#### 1. Clone the repo
+
+```shell
+git clone https://github.com/Stability-AI/generative-models.git
+cd generative-models
+```
+
+#### 2. Setting up the virtualenv
+
+This is assuming you have navigated to the `generative-models` root after cloning it.
+
+**NOTE:** This is tested under `python3.10`. For other python versions, you might encounter version conflicts.
+
+**PyTorch 2.0**
+
+```shell
+# install required packages from pypi
+python3 -m venv .pt2
+source .pt2/bin/activate
+pip3 install -r requirements/pt2.txt
+```
+
+#### 3. Install `sgm`
+
+```shell
+pip3 install .
+```
+
+#### 4. Install `sdata` for training
+
+```shell
+pip3 install -e git+https://github.com/Stability-AI/datapipelines.git@main#egg=sdata
+```
+
+## Packaging
+
+This repository uses PEP 517 compliant packaging using [Hatch](https://hatch.pypa.io/latest/).
+
+To build a distributable wheel, install `hatch` and run `hatch build`
+(specifying `-t wheel` will skip building a sdist, which is not necessary).
+
+```
+pip install hatch
+hatch build -t wheel
+```
+
+You will find the built package in `dist/`. You can install the wheel with `pip install dist/*.whl`.
+
+Note that the package does **not** currently specify dependencies; you will need to install the required packages,
+depending on your use case and PyTorch version, manually.
+
+## Inference
+
+We provide a [streamlit](https://streamlit.io/) demo for text-to-image and image-to-image sampling
+in `scripts/demo/sampling.py`.
+We provide file hashes for the complete file as well as for only the saved tensors in the file (
+see [Model Spec](https://github.com/Stability-AI/ModelSpec) for a script to evaluate that).
+The following models are currently supported:
+
+- [SDXL-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0)

+- [SD-2.1-768](https://huggingface.co/stabilityai/stable-diffusion-2-1/blob/main/v2-1_768-ema-pruned.safetensors)
+
+**Weights for SDXL**:
+
+**SDXL-1.0:**
+The weights of SDXL-1.0 are available (subject to
+a [`CreativeML Open RAIL++-M` license](model_licenses/LICENSE-SDXL1.0)) here:
+
+- base model: https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0/
+- refiner model: https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-1.0/
+
+**SDXL-0.9:**
+The weights of SDXL-0.9 are available and subject to a [research license](model_licenses/LICENSE-SDXL0.9).
+If you would like to access these models for your research, please apply using one of the following links:
+[SDXL-base-0.9 model](https://huggingface.co/stabilityai/stable-diffusion-xl-base-0.9),
+and [SDXL-refiner-0.9](https://huggingface.co/stabilityai/stable-diffusion-xl-refiner-0.9).
+This means that you can apply for any of the two links - and if you are granted - you can access both.
+Please log in to your Hugging Face Account with your organization email to request access.
+
+After obtaining the weights, place them into `checkpoints/`.
+Next, start the demo using
+
+```
+streamlit run scripts/demo/sampling.py --server.port <your_port>
+```
+
+### Invisible Watermark Detection
+
+Images generated with our code use the
+[invisible-watermark](https://github.com/ShieldMnt/invisible-watermark/)
+library to embed an invisible watermark into the model output. We also provide
+a script to easily detect that watermark. Please note that this watermark is
+not the same as in previous Stable Diffusion 1.x/2.x versions.
+
+To run the script you need to either have a working installation as above or
+try an _experimental_ import using only a minimal amount of packages:
+
+```bash
+python -m venv .detect
+source .detect/bin/activate
+
+pip install "numpy>=1.17" "PyWavelets>=1.1.1" "opencv-python>=4.1.0.25"
+pip install --no-deps invisible-watermark
+```
+
+To run the script you need to have a working installation as above. The script
+is then useable in the following ways (don't forget to activate your
+virtual environment beforehand, e.g. `source .pt1/bin/activate`):
+
+```bash
+# test a single file
+python scripts/demo/detect.py <your filename here>
+# test multiple files at once
+python scripts/demo/detect.py <filename 1> <filename 2> ... <filename n>
+# test all files in a specific folder
+python scripts/demo/detect.py <your folder name here>/*
+```
+
+## Training:
+
+We are providing example training configs in `configs/example_training`. To launch a training, run
+
+```
+python main.py --base configs/<config1.yaml> configs/<config2.yaml>
+```
+
+where configs are merged from left to right (later configs overwrite the same values).
+This can be used to combine model, training and data configs. However, all of them can also be
+defined in a single config. For example, to run a class-conditional pixel-based diffusion model training on MNIST,
+run
+
+```bash
+python main.py --base configs/example_training/toy/mnist_cond.yaml
+```
+
+**NOTE 1:** Using the non-toy-dataset
+configs `configs/example_training/imagenet-f8_cond.yaml`, `configs/example_training/txt2img-clipl.yaml`
+and `configs/example_training/txt2img-clipl-legacy-ucg-training.yaml` for training will require edits depending on the
+used dataset (which is expected to stored in tar-file in
+the [webdataset-format](https://github.com/webdataset/webdataset)). To find the parts which have to be adapted, search
+for comments containing `USER:` in the respective config.
+
+**NOTE 2:** This repository supports both `pytorch1.13` and `pytorch2`for training generative models. However for
+autoencoder training as e.g. in `configs/example_training/autoencoder/kl-f4/imagenet-attnfree-logvar.yaml`,
+only `pytorch1.13` is supported.
+
+**NOTE 3:** Training latent generative models (as e.g. in `configs/example_training/imagenet-f8_cond.yaml`) requires
+retrieving the checkpoint from [Hugging Face](https://huggingface.co/stabilityai/sdxl-vae/tree/main) and replacing
+the `CKPT_PATH` placeholder in [this line](configs/example_training/imagenet-f8_cond.yaml#81). The same is to be done
+for the provided text-to-image configs.
+
+### Building New Diffusion Models
+
+#### Conditioner
+
+The `GeneralConditioner` is configured through the `conditioner_config`. Its only attribute is `emb_models`, a list of
+different embedders (all inherited from `AbstractEmbModel`) that are used to condition the generative model.
+All embedders should define whether or not they are trainable (`is_trainable`, default `False`), a classifier-free
+guidance dropout rate is used (`ucg_rate`, default `0`), and an input key (`input_key`), for example, `txt` for
+text-conditioning or `cls` for class-conditioning.
+When computing conditionings, the embedder will get `batch[input_key]` as input.
+We currently support two to four dimensional conditionings and conditionings of different embedders are concatenated
+appropriately.
+Note that the order of the embedders in the `conditioner_config` is important.
+
+#### Network
+
+The neural network is set through the `network_config`. This used to be called `unet_config`, which is not general
+enough as we plan to experiment with transformer-based diffusion backbones.
+
+#### Loss
+
+The loss is configured through `loss_config`. For standard diffusion model training, you will have to
+set `sigma_sampler_config`.
+
+#### Sampler config
+
+As discussed above, the sampler is independent of the model. In the `sampler_config`, we set the type of numerical
+solver, number of steps, type of discretization, as well as, for example, guidance wrappers for classifier-free
+guidance.
+
+### Dataset Handling
+
+For large scale training we recommend using the data pipelines from
+our [data pipelines](https://github.com/Stability-AI/datapipelines) project. The project is contained in the requirement
+and automatically included when following the steps from the [Installation section](#installation).
+Small map-style datasets should be defined here in the repository (e.g., MNIST, CIFAR-10, ...), and return a dict of
+data keys/values,
+e.g.,
+
+```python
+example = {"jpg": x,  # this is a tensor -1...1 chw
+           "txt": "a beautiful image"}
+```
+
+where we expect images in -1...1, channel-first format.

+Copyright (c) 2023 Stability AI CreativeML Open RAIL++-M License dated July 26, 2023
+
+Section I: PREAMBLE Multimodal generative models are being widely adopted and used, and
+have the potential to transform the way artists, among other individuals, conceive and
+benefit from AI or ML technologies as a tool for content creation. Notwithstanding the
+current and potential benefits that these artifacts can bring to society at large, there
+are also concerns about potential misuses of them, either due to their technical
+limitations or ethical considerations. In short, this license strives for both the open
+and responsible downstream use of the accompanying model. When it comes to the open
+character, we took inspiration from open source permissive licenses regarding the grant
+of IP rights. Referring to the downstream responsible use, we added use-based
+restrictions not permitting the use of the model in very specific scenarios, in order
+for the licensor to be able to enforce the license in case potential misuses of the
+Model may occur. At the same time, we strive to promote open and responsible research on
+generative models for art and content generation. Even though downstream derivative
+versions of the model could be released under different licensing terms, the latter will
+always have to include - at minimum - the same use-based restrictions as the ones in the
+original license (this license). We believe in the intersection between open and
+responsible AI development; thus, this agreement aims to strike a balance between both
+in order to enable responsible open-science in the field of AI. This CreativeML Open
+RAIL++-M License governs the use of the model (and its derivatives) and is informed by
+the model card associated with the model. NOW THEREFORE, You and Licensor agree as
+follows: Definitions "License" means the terms and conditions for use, reproduction, and
+Distribution as defined in this document. "Data" means a collection of information
+and/or content extracted from the dataset used with the Model, including to train,
+pretrain, or otherwise evaluate the Model. The Data is not licensed under this License.
+"Output" means the results of operating a Model as embodied in informational content
+resulting therefrom. "Model" means any accompanying machine-learning based assemblies
+(including checkpoints), consisting of learnt weights, parameters (including optimizer
+states), corresponding to the model architecture as embodied in the Complementary
+Material, that have been trained or tuned, in whole or in part on the Data, using the
+Complementary Material. "Derivatives of the Model" means all modifications to the Model,
+works based on the Model, or any other model which is created or initialized by transfer
+of patterns of the weights, parameters, activations or output of the Model, to the other
+model, in order to cause the other model to perform similarly to the Model, including -
+but not limited to - distillation methods entailing the use of intermediate data
+representations or methods based on the generation of synthetic data by the Model for
+training the other model. "Complementary Material" means the accompanying source code
+and scripts used to define, run, load, benchmark or evaluate the Model, and used to
+prepare data for training or evaluation, if any. This includes any accompanying
+documentation, tutorials, examples, etc, if any. "Distribution" means any transmission,
+reproduction, publication or other sharing of the Model or Derivatives of the Model to a
+third party, including providing the Model as a hosted service made available by
+electronic or other remote means - e.g. API-based or web access. "Licensor" means the
+copyright owner or entity authorized by the copyright owner that is granting the
+License, including the persons or entities that may have rights in the Model and/or
+distributing the Model. "You" (or "Your") means an individual or Legal Entity exercising
+permissions granted by this License and/or making use of the Model for whichever purpose
+and in any field of use, including usage of the Model in an end-use application - e.g.
+chatbot, translator, image generator. "Third Parties" means individuals or legal
+entities that are not under common control with Licensor or You. "Contribution" means
+any work of authorship, including the original version of the Model and any
+modifications or additions to that Model or Derivatives of the Model thereof, that is
+intentionally submitted to Licensor for inclusion in the Model by the copyright owner or
+by an individual or Legal Entity authorized to submit on behalf of the copyright owner.
+For the purposes of this definition, "submitted" means any form of electronic, verbal,
+or written communication sent to the Licensor or its representatives, including but not
+limited to communication on electronic mailing lists, source code control systems, and
+issue tracking systems that are managed by, or on behalf of, the Licensor for the
+purpose of discussing and improving the Model, but excluding communication that is
+conspicuously marked or otherwise designated in writing by the copyright owner as "Not a
+Contribution." "Contributor" means Licensor and any individual or Legal Entity on behalf
+of whom a Contribution has been received by Licensor and subsequently incorporated
+within the Model.
+
+Section II: INTELLECTUAL PROPERTY RIGHTS Both copyright and patent grants apply to the
+Model, Derivatives of the Model and Complementary Material. The Model and Derivatives of
+the Model are subject to additional terms as described in
+
+Section III. Grant of Copyright License. Subject to the terms and conditions of this
+License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive,
+no-charge, royalty-free, irrevocable copyright license to reproduce, prepare, publicly
+display, publicly perform, sublicense, and distribute the Complementary Material, the
+Model, and Derivatives of the Model. Grant of Patent License. Subject to the terms and
+conditions of this License and where and as applicable, each Contributor hereby grants
+to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+(except as stated in this paragraph) patent license to make, have made, use, offer to
+sell, sell, import, and otherwise transfer the Model and the Complementary Material,
+where such license applies only to those patent claims licensable by such Contributor
+that are necessarily infringed by their Contribution(s) alone or by combination of their
+Contribution(s) with the Model to which such Contribution(s) was submitted. If You
+institute patent litigation against any entity (including a cross-claim or counterclaim
+in a lawsuit) alleging that the Model and/or Complementary Material or a Contribution
+incorporated within the Model and/or Complementary Material constitutes direct or
+contributory patent infringement, then any patent licenses granted to You under this
+License for the Model and/or Work shall terminate as of the date such litigation is
+asserted or filed. Section III: CONDITIONS OF USAGE, DISTRIBUTION AND REDISTRIBUTION
+Distribution and Redistribution. You may host for Third Party remote access purposes
+(e.g. software-as-a-service), reproduce and distribute copies of the Model or
+Derivatives of the Model thereof in any medium, with or without modifications, provided
+that You meet the following conditions: Use-based restrictions as referenced in
+paragraph 5 MUST be included as an enforceable provision by You in any type of legal
+agreement (e.g. a license) governing the use and/or distribution of the Model or
+Derivatives of the Model, and You shall give notice to subsequent users You Distribute
+to, that the Model or Derivatives of the Model are subject to paragraph 5. This
+provision does not apply to the use of Complementary Material. You must give any Third
+Party recipients of the Model or Derivatives of the Model a copy of this License; You
+must cause any modified files to carry prominent notices stating that You changed the
+files; You must retain all copyright, patent, trademark, and attribution notices
+excluding those notices that do not pertain to any part of the Model, Derivatives of the
+Model. You may add Your own copyright statement to Your modifications and may provide
+additional or different license terms and conditions - respecting paragraph 4.a. - for
+use, reproduction, or Distribution of Your modifications, or for any such Derivatives of
+the Model as a whole, provided Your use, reproduction, and Distribution of the Model
+otherwise complies with the conditions stated in this License. Use-based restrictions.
+The restrictions set forth in Attachment A are considered Use-based restrictions.
+Therefore You cannot use the Model and the Derivatives of the Model for the specified
+restricted uses. You may use the Model subject to this License, including only for
+lawful purposes and in accordance with the License. Use may include creating any content
+with, finetuning, updating, running, training, evaluating and/or reparametrizing the
+Model. You shall require all of Your users who use the Model or a Derivative of the
+Model to comply with the terms of this paragraph (paragraph 5). The Output You Generate.
+Except as set forth herein, Licensor claims no rights in the Output You generate using
+the Model. You are accountable for the Output you generate and its subsequent uses. No
+use of the output can contravene any provision as stated in the License.
+
+Section IV: OTHER PROVISIONS Updates and Runtime Restrictions. To the maximum extent
+permitted by law, Licensor reserves the right to restrict (remotely or otherwise) usage
+of the Model in violation of this License. Trademarks and related. Nothing in this
+License permits You to make use of Licensors’ trademarks, trade names, logos or to
+otherwise suggest endorsement or misrepresent the relationship between the parties; and
+any rights not expressly granted herein are reserved by the Licensors. Disclaimer of
+Warranty. Unless required by applicable law or agreed to in writing, Licensor provides
+the Model and the Complementary Material (and each Contributor provides its
+Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either
+express or implied, including, without limitation, any warranties or conditions of
+TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
+solely responsible for determining the appropriateness of using or redistributing the
+Model, Derivatives of the Model, and the Complementary Material and assume any risks
+associated with Your exercise of permissions under this License. Limitation of
+Liability. In no event and under no legal theory, whether in tort (including
+negligence), contract, or otherwise, unless required by applicable law (such as
+deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special, incidental, or
+consequential damages of any character arising as a result of this License or out of the
+use or inability to use the Model and the Complementary Material (including but not
+limited to damages for loss of goodwill, work stoppage, computer failure or malfunction,
+or any and all other commercial damages or losses), even if such Contributor has been
+advised of the possibility of such damages. Accepting Warranty or Additional Liability.
+While redistributing the Model, Derivatives of the Model and the Complementary Material
+thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty,
+indemnity, or other liability obligations and/or rights consistent with this License.
+However, in accepting such obligations, You may act only on Your own behalf and on Your
+sole responsibility, not on behalf of any other Contributor, and only if You agree to
+indemnify, defend, and hold each Contributor harmless for any liability incurred by, or
+claims asserted against, such Contributor by reason of your accepting any such warranty
+or additional liability. If any provision of this License is held to be invalid, illegal
+or unenforceable, the remaining provisions shall be unaffected thereby and remain valid
+as if such provision had not been set forth herein.
+
+END OF TERMS AND CONDITIONS
+
+Attachment A Use Restrictions
