+# Deploying Hugging Face Models with BentoML: DeepFloyd IF in Action
+
+<!-- {blog_metadata} -->
+<!-- {authors} -->
+
+Hugging Face provides a Hub platform that allows you to upload, share, and deploy your models with ease. It saves developers the time and computational resources required to train models from scratch. However, deploying models in a real-world production environment or in a cloud-native way can still present challenges.
+
+This is where BentoML comes into the picture. BentoML is an open-source platform for machine learning model serving and deployment. It is a unified framework for building, shipping, and scaling production-ready AI applications incorporating traditional, pre-trained, and generative models as well as Large Language Models. Here is how you use the BentoML framework from a high-level perspective:
+
+1. **Define a model**: Before you can use BentoML, you need a machine learning model (or multiple models). This model can be trained using a machine learning library such as TensorFlow and PyTorch.
+2. **Save the model**: Once you have a trained model, save it to the BentoML local Model Store, which is used for managing all your trained models locally as well as accessing them for serving.
+3. **Create a BentoML Service**: You create a `service.py` file to wrap the model and define the serving logic. It specifies [Runners](https://docs.bentoml.org/en/latest/concepts/runner.html) for models to run model inference at scale and exposes APIs to define how to process inputs and outputs.
+4. **Build a Bento**: By creating a configuration YAML file, you package all the models and the [Service](https://docs.bentoml.org/en/latest/concepts/service.html) into a [Bento](https://docs.bentoml.org/en/latest/concepts/bento.html), a deployable artifact containing all the code and dependencies.
+5. **Deploy the Bento**: Once the Bento is ready, you can containerize the Bento to create a Docker image and run it on Kubernetes. Alternatively, deploy the Bento directly to Yatai, an open-source, end-to-end solution for automating and running machine learning deployments on Kubernetes at scale.
+
+In this blog post, we will demonstrate how to integrate [DeepFloyd IF](https://huggingface.co/docs/diffusers/api/pipelines/if) with BentoML by following the above workflow.

+## A brief introduction to DeepFloyd IF
+
+DeepFloyd IF is a state-of-the-art, open-source text-to-image model. It stands apart from latent diffusion models like Stable Diffusion due to its distinct operational strategy and architecture.
+
+DeepFloyd IF delivers a high degree of photorealism and sophisticated language understanding. Unlike Stable Diffusion, DeepFloyd IF works directly in pixel space, leveraging a modular structure that encompasses a frozen text encoder and three cascaded pixel diffusion modules. Each module plays a unique role in the process: Stage 1 is responsible for the creation of a base 64x64 px image, which is then progressively upscaled to 1024x1024 px across Stage 2 and Stage 3. Another critical aspect of DeepFloyd IF’s uniqueness is its integration of a Large Language Model (T5-XXL-1.1) to encode prompts, which offers superior understanding of complex prompts. For more information, see this [Stability AI blog post about DeepFloyd IF](https://stability.ai/blog/deepfloyd-if-text-to-image-model).
+
+To make sure your DeepFloyd IF application runs in high performance in production, you may want to allocate and manage your resources wisely. In this respect, BentoML allows you to scale the Runners independently for each Stage. For example, you can use more Pods for your Stage 1 Runners or allocate more powerful GPU servers to them.
+
+## Preparing the environment
+
+[This GitHub repository](https://github.com/bentoml/IF-multi-GPUs-demo) stores all necessary files for this project. To run this project locally, make sure you have the following:
+
+- Python 3.8+
+- `pip` installed
+- At least 2x16GB VRAM GPU or 1x40 VRAM GPU. For this project, we used a machine of type `n1-standard-16` from Google Cloud plus 64 GB of RAM and 2 NVIDIA T4 GPUs. Note that while it is possible to run IF on a single T4, it is not recommended for production-grade serving
+
+Once the prerequisites are met, clone the project repository to your local machine and navigate to the target directory.
+
+```bash
+git clone https://github.com/bentoml/IF-multi-GPUs-demo.git
+cd IF-multi-GPUs-demo
+```
+
+Before building the application, let’s briefly explore the key files within this directory:
+
+- `import_models.py`: Defines the models for each stage of the [`IFPipeline`](https://huggingface.co/docs/diffusers/api/pipelines/if). You use this file to download all the models to your local machine so that you can package them into a single Bento.
+- `requirements.txt`: Defines all the packages and dependencies required for this project.
+- `service.py`: Defines a BentoML Service, which contains three Runners created using the `to_runner` method and exposes an API for generating images. The API takes a JSON object as input (i.e. prompts and negative prompts) and returns an image as output by using a sequence of models.
+- `start-server.py`: Starts a BentoML HTTP server through the Service defined in `service.py` and creates a Gradio web interface for users to enter prompts to generate images.
+- `bentofile.yaml`: Defines the metadata of the Bento to be built, including the Service, Python packages, and models.
+
+We recommend you create a Virtual Environment for dependency isolation. For example, run the following command to activate `myenv`:
+
+```bash
+python -m venv venv
+source venv/bin/activate
+```
+
+Install the required dependencies:
+
+```bash
+pip install -r requirements.txt
+```
+
+If you haven’t previously downloaded models from Hugging Face using the command line, you must log in first:
+
+```bash
+pip install -U huggingface_hub
+huggingface-cli login
+```
+
+## Downloading the model to the BentoML Model Store
+
+As mentioned above, you need to download all the models used by each DeepFloyd IF stage. Once you have set up the environment, run the following command to download models to your local Model store. The process may take some time.
+
+```bash
+python import_models.py
+```
+
+Once the downloads are complete, view the models in the Model store.
+
+```bash
+$ bentoml models list
+
+Tag                                                                 Module                Size       Creation Time
+sd-upscaler:bb2ckpa3uoypynry                                        bentoml.diffusers     16.29 GiB  2023-07-06 10:15:53
+if-stage2:v1.0                                                      bentoml.diffusers     13.63 GiB  2023-07-06 09:55:49
+if-stage1:v1.0                                                      bentoml.diffusers     19.33 GiB  2023-07-06 09:37:59
+```
+
+## Starting a BentoML Service
+
+You can directly run the BentoML HTTP server with a web UI powered by Gradio using the `start-server.py` file, which is the entry point of this application. It provides various options for customizing the execution and managing GPU allocation among different Stages. You may use different commands depending on your GPU setup:
+
+- For a GPU with over 40GB VRAM, run all models on the same GPU.
+
+  ```bash
+  python start-server.py
+  ```
+
+- For two Tesla T4 with 15GB VRAM each, assign the Stage 1 model to the first GPU, and the Stage 2 and Stage 3 models to the second GPU.
+
+  ```bash
+  python start-server.py --stage1-gpu=0 --stage2-gpu=1 --stage3-gpu=1
+  ```
+
+- For one Tesla T4 with 15GB VRAM and two additional GPUs with smaller VRAM size, assign the Stage 1 model to T4, and Stage 2 and Stage 3 models to the second and third GPUs respectively.
+
+  ```bash
+  python start-server.py --stage1-gpu=0 --stage2-gpu=1 --stage3-gpu=2
+  ```
+
+To see all customizable options (like the server’s port), run:
+
+```bash
+python start-server.py --help
+```
+
+## Testing the server
+
+Once the server starts, you can visit the web UI at http://localhost:7860. The BentoML API endpoint is also accessible at http://localhost:3000. Here is an example of a prompt and a negative prompt.
+
+Prompt:
+
+> orange and black, head shot of a woman standing under street lights, dark theme, Frank Miller, cinema, ultra realistic, ambiance, insanely detailed and intricate, hyper realistic, 8k resolution, photorealistic, highly textured, intricate details
+
+Negative prompt:
+
+> tiling, poorly drawn hands, poorly drawn feet, poorly drawn face, out of frame, mutation, mutated, extra limbs, extra legs, extra arms, disfigured, deformed, cross-eye, body out of frame, blurry, bad art, bad anatomy, blurred, text, watermark, grainy

+```
+
+The Bento is now ready for serving in production.
+
+```bash
+bentoml serve deepfloyd-if:6ufnybq3vwszgnry
+```
+
+To deploy the Bento in a more cloud-native way, generate a Docker image by running the following command:
+
+```bash
+bentoml containerize deepfloyd-if:6ufnybq3vwszgnry
+```
+
+You can then deploy the model on Kubernetes.
