ChatInterface 

gradio.ChatInterface(fn, ยทยทยท)

Description

ChatInterface is Gradio's high-level abstraction for creating chatbot UIs, and allows you to create a web-based demo around a chatbot model in a few lines of code. Only one parameter is required: fn, which takes a function that governs the response of the chatbot based on the user input and chat history. Additional parameters can be used to control the appearance and behavior of the demo.

Example Usage 

import gradio as gr

def echo(message, history):
    return message

demo = gr.ChatInterface(fn=echo, examples=["hello", "hola", "merhaba"], title="Echo Bot")
demo.launch()

Initialization

Parameter Description
fn

Callable

required

The function to wrap the chat interface around. Should accept two parameters: a string input message and list of two-element lists of the form [[user_message, bot_message], ...] representing the chat history, and return a string response. See the Chatbot documentation for more information on the chat history format.
multimodal

bool

default: False

If True, the chat interface will use a gr.MultimodalTextbox component for the input, which allows for the uploading of multimedia files. If False, the chat interface will use a gr.Textbox component for the input.
chatbot

Chatbot | None

default: None

An instance of the gr.Chatbot component to use for the chat interface, if you would like to customize the chatbot properties. If not provided, a default gr.Chatbot component will be created.
textbox

Textbox | MultimodalTextbox | None

default: None

An instance of the gr.Textbox or gr.MultimodalTextbox component to use for the chat interface, if you would like to customize the textbox properties. If not provided, a default gr.Textbox or gr.MultimodalTextbox component will be created.
additional_inputs

str | Component | list[str | Component] | None

default: None

An instance or list of instances of gradio components (or their string shortcuts) to use as additional inputs to the chatbot. If components are not already rendered in a surrounding Blocks, then the components will be displayed under the chatbot, in an accordion.
additional_inputs_accordion_name

str | None

default: None

Deprecated. Will be removed in a future version of Gradio. Use the additional_inputs_accordion parameter instead.
additional_inputs_accordion

str | Accordion | None

default: None

If a string is provided, this is the label of the gr.Accordion to use to contain additional inputs. A gr.Accordion object can be provided as well to configure other properties of the container holding the additional inputs. Defaults to a gr.Accordion(label="Additional Inputs", open=False). This parameter is only used if additional_inputs is provided.
examples

list[str] | list[dict[str, str | list]] | list[list] | None

default: None

Sample inputs for the function; if provided, appear below the chatbot and can be clicked to populate the chatbot input. Should be a list of strings if multimodal is False, and a list of dictionaries (with keys text and files) if multimodal is True.
cache_examples

bool | Literal['lazy'] | None

default: None

If True, caches examples in the server for fast runtime in examples. The default option in HuggingFace Spaces is True. The default option elsewhere is False.
examples_per_page

int

default: 10

If examples are provided, how many to display per page.
title

str | None

default: None

a title for the interface; if provided, appears above chatbot in large font. Also used as the tab title when opened in a browser window.

Custom css as a string or path to a css file. This css will be included in the demo webpage.
js

str | None

default: None

Custom js as a string or path to a js file. The custom js should be in the form of a single js function. This function will automatically be executed when the page loads. For more flexibility, use the head parameter to insert js inside <script> tags.
head

str | None

default: None

Custom html to insert into the head of the demo webpage. This can be used to add custom meta tags, multiple scripts, stylesheets, etc. to the page.
analytics_enabled

bool | None

default: None

Whether to allow basic telemetry. If None, will use GRADIO_ANALYTICS_ENABLED environment variable if defined, or default to True.
submit_btn

str | None | Button

default: "Submit"

Text to display on the submit button. If None, no button will be displayed. If a Button object, that button will be used.
stop_btn

str | None | Button

default: "Stop"

Text to display on the stop button, which replaces the submit_btn when the submit_btn or retry_btn is clicked and response is streaming. Clicking on the stop_btn will halt the chatbot response. If set to None, stop button functionality does not appear in the chatbot. If a Button object, that button will be used as the stop button.
retry_btn

str | None | Button

default: "๐Ÿ”„ Retry"

Text to display on the retry button. If None, no button will be displayed. If a Button object, that button will be used.

bool

default: True

If True, autofocuses to the textbox when the page loads.
concurrency_limit

int | None | Literal['default']

default: "default"

If set, this is the maximum number of chatbot submissions that can be running simultaneously. Can be set to None to mean no limit (any number of chatbot submissions can be running simultaneously). Set to "default" to use the default concurrency limit (defined by the default_concurrency_limit parameter in .queue(), which is 1 by default).
fill_height

bool

default: True

If True, the chat interface will expand to the height of window.
delete_cache

tuple[int, int] | None

default: None

A tuple corresponding [frequency, age] both expressed in number of seconds. Every frequency seconds, the temporary files created by this Blocks instance will be deleted if more than age seconds have passed since the file was created. For example, setting this to (86400, 86400) will delete temporary files every day. The cache will be deleted entirely when the server restarts. If None, no cache deletion will occur.
