+# Stable Diffusion 3 Medium TensorRT
+## Introduction
+
+This repository hosts the TensorRT version of **Stable Diffusion 3 Medium** created in collaboration with [NVIDIA](https://huggingface.co/nvidia). The optimized versions give substantial improvements in speed and efficiency.
+
+Stable Diffusion 3 Medium is a fast generative text-to-image model with greatly improved performance in multi-subject prompts, image quality, and spelling abilities.
+
+## Model Details
+
+### Model Description
+Stable Diffusion 3 Medium combines a diffusion transformer architecture and flow matching.
+
+- **Developed by:** Stability AI
+- **Model type:** MMDiT text-to-image model
+- **Model Description:** This is a conversion of the [Stable Diffusion 3 Medium](https://huggingface.co/stabilityai/stable-diffusion-3-medium) model
+
+
+## Performance using TensorRT 10.1
+#### Timings for 50 steps at 1024x1024
+
+| Accelerator | CLIP-G | CLIP-L | T5XXL | MMDiT | VAE Decoder | Total |
+|-------------|-------------|--------------|---------------|-----------------------|---------------------|------------------------|
+| A100 | 11.95 ms | 5.04 ms | 21.39 ms | 5468.17 ms | 72.25 ms | 5622.47 ms |
+
+#### Timings for 30 steps at 1024x1024 with input image conditioning
+
+| Accelerator | VAE Encoder | CLIP-G | CLIP-L | T5XXL | MMDiT | VAE Decoder | Total |
+|-------------|----------------|-------------|--------------|---------------|-----------------------|---------------------|----------------|
+| A100 | 37.04 ms | 12.07 ms | 5.07 ms | 21.49 ms | 3340.69 ms | 72.02 ms | 3531.49 ms |
+
+
+## Int8 quantization with [TensorRT Model Optimizer](https://github.com/NVIDIA/TensorRT-Model-Optimizer)
+The MMDiT in Stable Diffusion 3 Medium can be further optimized with INT8 quantization using TensorRT Model Optimizer. The estimated end-to-end speedup comparing TensorRT fp16 and TensorRT int8 is 1.2x~1.4x on various NVidia GPUs. The memory saving is about 2x for the int8 MMDiT engine compared with the fp16 counterpart. The image quality can be maintained with minimal to negligible degradation.
+
+## Usage Example
+<!-- Finalize the branch and namespace -->
+1. Follow the [setup instructions](https://github.com/NVIDIA/TensorRT/blob/release/sd3/demo/Diffusion/README.md) on launching a TensorRT NGC container.
+```shell
+git clone https://github.com/NVIDIA/TensorRT.git
+cd TensorRT
+git checkout release/sd3
+docker run --rm -it --gpus all -v $PWD:/workspace nvcr.io/nvidia/pytorch:24.05-py3 /bin/bash
+```
+
+2. Download the Stable Diffusion 3 Medium TensorRT files from this repo
+```shell
+git lfs install 
+git clone https://huggingface.co/stabilityai/stable-diffusion-3-medium-tensorrt
+cd stable-diffusion-3-medium-tensorrt
+git lfs pull
+cd ..
+```
+
+3. Install libraries and requirements
+```shell
+cd demo/Diffusion
+python3 -m pip install --upgrade pip
+pip3 install -r requirements.txt
+python3 -m pip install --pre --upgrade --extra-index-url https://pypi.nvidia.com tensorrt-cu12
+```
+
+
+4. Perform TensorRT optimized inference:
+
+ - **Stable Diffusion 3 Medium**
+ 
+ Works best for 1024x1024 images. The first invocation produces plan files in --engine-dir specific to the accelerator being run on and are reused for later invocations. 
+ ```
+ python3 demo_txt2img_sd3.py \
+ ""Astronaut in a jungle, cold color palette, muted colors, detailed, 8k"" \
+ --version=sd3 \
+ --onnx-dir /workspace/sd3-tensorrt/ \
+ --engine-dir /workspace/sd3-tensorrt/engine \
+ --seed 42 \
+ --width 1024 \
+ --height 1024 \
+ --build-static-batch \
+ --use-cuda-graph
+ ```
+
+ - **Stable Diffusion 3 Medium with input image conditioning**
+ 
+ Provide an input image conditioning using below. Works best for 1024x1024 but may also work at 512x512.
+ ```
+ wget https://raw.githubusercontent.com/CompVis/latent-diffusion/main/data/inpainting_examples/overture-creations-5sI6fQgYIuo.png -O dog-on-bench.png
+
+ python3 demo_txt2img_sd3.py \
+ """dog wearing a sweater and a blue collar""" \
+ --version=sd3 \
+ --onnx-dir /workspace/sd3-tensorrt/ \
+ --engine-dir /workspace/sd3-tensorrt/engine \
+ --seed 42 \
+ --width 1024 \
+ --height 1024 \
+ --input-image dog-on-bench.png \
+ --build-static-batch \
+ --use-cuda-graph
+ ```
