1. Install Diffusers for my environment with `uv pip install &quot;diffusers[torch]&quot;`.
2. If I need gated Hub models, help me authenticate to the Hugging Face Hub.
3. Install Diffusers coding agent skills with `diffusers-cli skills add diffusers-cli`. Pass `--cursor`, `--claude`, or `--codex` if auto-detect fails. Optionally pass `--all` to install every skill in the registry.
4. Run a first text-to-image with DiffusionPipeline or `diffusers-cli run`, using a small or current Quickstart model and the right `device_map` for my machine.
5. Ask what I want next and point me at the matching docs.<!----></pre></div><!----> <!--[1--><h2 class="relative group"><a id="diffusionpipeline" class="header-link block pr-1.5 text-lg no-hover:hidden with-hover:absolute with-hover:p-1.5 with-hover:opacity-0 with-hover:group-hover:opacity-100 with-hover:right-full" href="#diffusionpipeline"><span><svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" aria-hidden="true" role="img" width="1em" height="1em" preserveAspectRatio="xMidYMid meet" viewBox="0 0 256 256"><path d="M167.594 88.393a8.001 8.001 0 0 1 0 11.314l-67.882 67.882a8 8 0 1 1-11.314-11.315l67.882-67.881a8.003 8.003 0 0 1 11.314 0zm-28.287 84.86l-28.284 28.284a40 40 0 0 1-56.567-56.567l28.284-28.284a8 8 0 0 0-11.315-11.315l-28.284 28.284a56 56 0 0 0 79.196 79.197l28.285-28.285a8 8 0 1 0-11.315-11.314zM212.852 43.14a56.002 56.002 0 0 0-79.196 0l-28.284 28.284a8 8 0 1 0 11.314 11.314l28.284-28.284a40 40 0 0 1 56.568 56.567l-28.285 28.285a8 8 0 0 0 11.315 11.314l28.284-28.284a56.065 56.065 0 0 0 0-79.196z" fill="currentColor"></path></svg><!----></span></a> <span><!---->DiffusionPipeline<!----></span></h2><!--]--><!----> <p><a href="/docs/diffusers/main/vi/api/pipelines/overview#diffusers.DiffusionPipeline">DiffusionPipeline</a> đóng gói các thành phần của một mô hình khuếch tán (text encoder, scheduler, UNet hoặc DiT, và VAE) vào một lớp duy nhất để suy luận.
