Gradio
When to Use
Use this skill when a user wants a Gradio demo, UI prototype, or Python-based ML interface.
Gradio is a Python library for building interactive web UIs and ML demos. This skill covers the core API, patterns, and examples.
Guides
Detailed guides on specific topics (read these when relevant):
Core Patterns Interface (high-level): wraps a function with input/output components.
import gradio as gr
def greet (name ):
return f"Hello {name} !"
gr.Interface(fn=greet, inputs="text" , outputs="text" ).launch()
Blocks (low-level): flexible layout with explicit event wiring.
import gradio as gr
with gr.Blocks() as demo:
name = gr.Textbox(label="Name" )
output = gr.Textbox(label="Greeting" )
btn = gr.Button("Greet" )
btn.click(fn=lambda n: f"Hello {n} !" , inputs=name, outputs=output)
demo.launch()
ChatInterface : high-level wrapper for chatbot UIs.
import gradio as gr
def respond (message, history ):
return f"You said: {message} "
gr.ChatInterface(fn=respond).launch()

Custom HTML Components If a task requires significant customization of an existing component or a component that doesn't exist in Gradio, you can create one with gr.HTML. It supports html_template (with ${} JS expressions and {{}} Handlebars syntax), css_template for scoped styles, and js_on_load for interactivity — where props.value updates the component value and trigger('event_name') fires Gradio events. For reuse, subclass gr.HTML and define api_info() for API/MCP support. See the full guide .
Here's an example that shows how to create and use these kinds of components:
import gradio as gr
class StarRating (gr.HTML):
def __init__ (self, label, value=0 , **kwargs ):
html_template = """
<h2>${label} rating:</h2>
${Array.from({length: 5}, (_, i) => `<img class='${i < value ? '' : 'faded'}' src='https://upload.wikimedia.org/wikipedia/commons/d/df/Award-star-gold-3d.svg'>`).join('')}
"""
css_template = """
img { height: 50px; display: inline-block; cursor: pointer; }
.faded { filter: grayscale(100%); opacity: 0.3; }
"""
js_on_load = """
const imgs = element.querySelectorAll('img');
imgs.forEach((img, index) => {
img.addEventListener('click', () => {
props.value = index + 1;
});
});
"""
super ().__init__(value=value, label=label, html_template=html_template, css_template=css_template, js_on_load=js_on_load, **kwargs)
def api_info (self ):
return {"type" : "integer" , "minimum" : 0 , "maximum" : 5 }
with gr.Blocks() as demo:
gr.Markdown("# Restaurant Review" )
food_rating = StarRating(label="Food" , value=3 )
service_rating = StarRating(label="Service" , value=3 )
ambience_rating = StarRating(label="Ambience" , value=3 )
average_btn = gr.Button("Calculate Average Rating" )
rating_output = StarRating(label="Average" , value=3 )
def calculate_average (food, service, ambience ):
return round ((food + service + ambience) / 3 )
average_btn.click(
fn=calculate_average,
inputs=[food_rating, service_rating, ambience_rating],
outputs=rating_output
)
demo.launch()

Prediction CLI The gradio CLI includes info and predict commands for interacting with Gradio apps programmatically. These are especially useful for coding agents that need to use Spaces in their workflows.
gradio info — Discover endpoints and parametersgradio info <space_id_or_url>
Returns a JSON payload describing all endpoints, their parameters (with types and defaults), and return values.
gradio info gradio/calculator
File-type parameters show "type": "filepath" with instructions to include "meta": {"_type": "gradio.FileData"} — this signals the file will be uploaded to the remote server.
gradio predict — Send predictionsgradio predict <space_id_or_url> <endpoint> <json_payload>
Returns a JSON object with named output keys.
gradio predict gradio/calculator /predict '{"num1": 5, "operation": "multiply", "num2": 3}'
gradio predict black-forest-labs/FLUX.2-dev /infer '{"prompt": "A majestic dragon"}'
gradio predict gradio/image_mod /predict '{"image": {"path": "/path/to/image.png", "meta": {"_type": "gradio.FileData"}}}'
Both commands accept --token for accessing private Spaces.

Limitations
Use this skill only when the task clearly matches the scope described above.
Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
