Wire It, Run It, Deploy It: AI Workflows in Gradio

Most interesting AI apps are pipelines. You generate an image, then cut out its background if you want to, or edit it into something new. You write a script, then generate a voice for it, or swap the voice while keeping the script the same. We usually wire these steps together in Python, and the moment something looks off we go back to print-debugging to find which step produced the odd value.

gr.Workflow, built right into Gradio, makes the pipeline the interface. You describe your steps as a graph of typed nodes, and Gradio serves a drag-and-drop canvas where every node is runnable and every intermediate result is visible. The same graph is also a REST API and a one-command deploy to Hugging Face Spaces.

The best way to get the idea is to see a few workflows in action. Every app below is a live Huggingface Space you can open, run, and duplicate.

Edit an Image

Upload an image, type an edit ("turn it into a snowy winter scene", "add sunglasses", "make the car red"), and get the edited photo back. The whole app is a single node calling Qwen-Image-Edit on Hugging Face Inference Providers.

Chain real models into a media studio

One graph, three pipelines. Start with a prompt and generate an image with FLUX, then pass it to a background-removal Gradio Space to turn it into a sticker. A topic becomes a voiceover through a text-to-speech Gradio Space, while the same topic becomes a catchy episode title through an LLM call.

That’s one canvas, two model calls through Hugging Face Inference Providers, and two calls to Gradio Spaces.

Since this is a workflow, each of the three outputs also gets its own REST endpoint: /sticker, /voiceover, and /episode_title. You can call any of them directly from code without opening the UI. See Call it from code below for a runnable example.

Fan-out image generation in parallel

Type in one idea, and it turns into a set of generated artwork all at once: a base image from FLUX, two AI re-imaginings of that image (a soft watercolor version and a neon cyberpunk take), and a gallery title written by an LLM.

Each image is generated directly from the prompt by a model node using Inference Providers, while the title comes from an fn node that calls an LLM. This is the fan-out pattern in action: one idea can feed multiple operators simultaneously, all generating in parallel.

Profile a Hugging Face dataset

Type in a Hugging Face dataset ID, such as stanfordnlp/imdb or mteb/tweet_sentiment_extraction, and a single input fans out to four operator nodes that analyze the dataset live using the Datasets Server API.

You get an overview card, a preview of the first few rows, per-column statistics, and a distribution chart, all computed independently and in parallel. That’s the power of workflows!

Run your own GPU model

Every node so far reaches out to Hugging Face. But an fn node is just Python, which means it can also run a model inside the Space on a GPU.

Decorate the bound function with @spaces.GPU and, when the node runs, ZeroGPU grabs a GPU for that call, runs the model, and releases it. We don't always need to rely on Inference Providers or existing Gradio Spaces.

Check out this demo that animates a still image using Lightricks/LTX-Video loaded through Diffusers, running entirely through one node. gr.Workflow doesn't need to know anything about your GPU setup. It simply calls the bound function.
