   The `rocm/pytorch-xdit <{{ docker.docker_hub_url }}>`_ Docker image offers
   a prebuilt, optimized inference environment based on `xDiT
   <https://github.com/xdit-project/xDiT>`_ for benchmarking diffusion-based
   video and image generation on AMD Instinct MI355X, MI350X (gfx950), MI325X,
   and MI300X (gfx942) GPUs.
   This image is based on ROCm {{docker.ROCm}} preview release via `TheRock <https://github.com/ROCm/TheRock>`_
   and includes the following software components:

   .. tab-set::

      .. tab-item:: {{ docker.pull_tag }}

         .. list-table::
            :header-rows: 1

            * - Software component
              - Version

            {% for component_name, component_version in docker.components.items() %}
            * - {{ component_name }}
              - {{ component_version }}
            {% endfor %}

Follow this guide to pull the required image, spin up a container, download the model, and run a benchmark.
For preview and development releases, see `amdsiloai/pytorch-xdit <https://hub.docker.com/r/amdsiloai/pytorch-xdit>`_.

      .. note::

         To learn more about your specific model see the `{{ model.model }} model card on Hugging Face <{{ model.url }}>`_
         or visit the `GitHub page <{{ model.github }}>`__. Note that some models require access authorization before use via an
         external license agreement through a third party.

   {% endfor %}

System validation
=================

Before running AI workloads, it's important to validate that your AMD hardware is configured
correctly and performing optimally.

If you have already validated your system settings, including aspects like NUMA
auto-balancing, you can skip this step. Otherwise, complete the procedures in
the `System validation and optimization
<https://rocm.docs.amd.com/en/latest/how-to/rocm-for-ai/system-setup/prerequisite-system-validation.html>`__
guide to properly configure your system settings before starting.

Pull the Docker image
=====================

.. datatemplate:yaml:: /data/how-to/rocm-for-ai/inference/previous-versions/xdit_25.10-inference-models.yaml

   {% set docker = data.xdit_diffusion_inference.docker %}

   For this tutorial, it's recommended to use the latest ``{{ docker.pull_tag }}`` Docker image.
   Pull the image using the following command:

   .. code-block:: shell

      docker pull {{ docker.pull_tag }}

Validate and benchmark
======================

Once the image has been downloaded you can follow these steps to
run benchmarks and generate outputs.

.. datatemplate:yaml:: /data/how-to/rocm-for-ai/inference/previous-versions/xdit_25.10-inference-models.yaml

   {% set model_groups = data.xdit_diffusion_inference.model_groups %}
   {% for model_group in model_groups %}
     {% for model in model_group.models %}

   .. container:: model-doc {{model.mad_tag}}

      The following commands are written for {{ model.model }}.
      See :ref:`xdit-video-diffusion-supported-models-2510` to switch to another available model.

     {% endfor %}
   {% endfor %}

.. _xdit-video-diffusion-setup-2510:

Prepare the model
-----------------

.. note::

   If you're using ROCm MAD to :ref:`run your model
   <xdit-video-diffusion-run-2510>`, you can skip this section. MAD will handle
   starting the container and downloading required models inside the container.

You can either use an existing Hugging Face cache or download the model fresh inside the container.

.. datatemplate:yaml:: /data/how-to/rocm-for-ai/inference/previous-versions/xdit_25.10-inference-models.yaml

   {% set docker = data.xdit_diffusion_inference.docker %}
   {% set model_groups = data.xdit_diffusion_inference.model_groups%}

   {% for model_group in model_groups %}
     {% for model in model_group.models %}
   .. container:: model-doc {{model.mad_tag}}

      .. tab-set::

         .. tab-item:: Option 1: Use existing Hugging Face cache

            If you already have models downloaded on your host system, you can mount your existing cache.

            1. Set your Hugging Face cache location.

               .. code-block:: shell

                  export HF_HOME=/your/hf_cache/location

            2. Download the model (if not already cached).

               .. code-block:: shell

                  huggingface-cli download {{ model.model_repo }} {% if model.revision %} --revision {{ model.revision }} {% endif %}

            3. Launch the container with mounted cache.

               .. code-block:: shell

                  docker run \
                      -it --rm \
                      --cap-add=SYS_PTRACE \
                      --security-opt seccomp=unconfined \
                      --user root \
                      --device=/dev/kfd \
                      --device=/dev/dri \
                      --group-add video \
                      --ipc=host \
                      --network host \
                      --privileged \
                      --shm-size 128G \
                      --name pytorch-xdit \
                      -e HSA_NO_SCRATCH_RECLAIM=1 \
                      -e OMP_NUM_THREADS=16 \
                      -e CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 \
                      -e HF_HOME=/app/huggingface_models \
                      -v $HF_HOME:/app/huggingface_models \
                      {{ docker.pull_tag }}

         .. tab-item:: Option 2: Download inside container

            If you prefer to keep the container self-contained or don't have an existing cache.

            1. Launch the container

               .. code-block:: shell

                  docker run \
                      -it --rm \
                      --cap-add=SYS_PTRACE \
                      --security-opt seccomp=unconfined \
                      --user root \
                      --device=/dev/kfd \
                      --device=/dev/dri \
                      --group-add video \
                      --ipc=host \
                      --network host \
                      --privileged \
                      --shm-size 128G \
                      --name pytorch-xdit \
                      -e HSA_NO_SCRATCH_RECLAIM=1 \
                      -e OMP_NUM_THREADS=16 \
                      -e CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 \
                      {{ docker.pull_tag }}

            2. Inside the container, set the Hugging Face cache location and download the model.

               .. code-block:: shell

                  export HF_HOME=/app/huggingface_models
                  huggingface-cli download {{ model.model_repo }} {% if model.revision %} --revision {{ model.revision }} {% endif %}

               .. warning::

                  Models will be downloaded to the container's filesystem and will be lost when the container is removed unless you persist the data with a volume.
     {% endfor %}
   {% endfor %}

.. _xdit-video-diffusion-run-2510:

Run inference
=============

You can benchmark models through `MAD <https://github.com/ROCm/MAD>`__-integrated automation or standalone
torchrun commands.

.. datatemplate:yaml:: /data/how-to/rocm-for-ai/inference/previous-versions/xdit_25.10-inference-models.yaml

   {% set model_groups = data.xdit_diffusion_inference.model_groups%}
   {% for model_group in model_groups %}
     {% for model in model_group.models %}

   .. container:: model-doc {{ model.mad_tag }}

      .. tab-set::

         .. tab-item:: MAD-integrated benchmarking

            1. Clone the ROCm Model Automation and Dashboarding (`<https://github.com/ROCm/MAD>`__) repository to a local
               directory and install the required packages on the host machine.

               .. code-block:: shell

                  git clone https://github.com/ROCm/MAD
                  cd MAD
                  pip install -r requirements.txt

            2. On the host machine, use this command to run the performance benchmark test on
               the `{{model.model}} <{{ model.url }}>`_ model using one node.

               .. code-block:: shell

                  export MAD_SECRETS_HFTOKEN="your personal Hugging Face token to access gated models"
                  madengine run \
                      --tags {{model.mad_tag}} \
                      --keep-model-dir \
                      --live-output
                     
            MAD launches a Docker container with the name
            ``container_ci-{{model.mad_tag}}``. The throughput and serving reports of the
            model are collected in the following paths: ``{{ model.mad_tag }}_throughput.csv``
            and ``{{ model.mad_tag }}_serving.csv``.

         .. tab-item:: Standalone benchmarking

            To run the benchmarks for {{ model.model }}, use the following command:

            .. code-block:: shell
            {% if model.model == "Hunyuan Video" %}
               cd /app/Hunyuanvideo
