<p>Input and output components define where data enters and exits your flow, but they don't have identical functionality.</p>
|
||
<p>Specifically, <strong>Chat Input and Output</strong> components are designed to facilitate conversational interactions where messages are exchanged in a cumulative dialogue.
|
||
The data handled by these components includes the message text plus additional metadata like senders, session IDs, and timestamps.</p>
|
||
<p>In contrast, <strong>Text Input and Output</strong> components are designed for simple string input and output that doesn't require the additional context and metadata associated with chat messages.
|
||
The data handled by these components is pared down to basic text strings.</p>

|

<p>The <strong>Chat Output</strong> component ingests <code>Message</code>, <code>Data</code>, or <code>DataFrame</code> data from other components, transforms it into <code>Message</code> data if needed, and then emits the final output as a chat message.
|
||
For information about these data types, see <a href="/data-types">Use Langflow data types</a>.</p>
|
||
<p>In the <strong>Playground</strong>, chat output is limited to the parts of the <code>Message</code> object that are relevant to the chat interface, such as the text response, sender name, and file attachments.
|
||
To see the metadata associated with a chat message, inspect the message logs in the <strong>Playground</strong>.</p>
|
||
<p>When using the Langflow API, the API response includes the <strong>Chat Output</strong> <code>Message</code> object along with other response data from the flow run.
|
||
Langflow API responses can be extremely verbose, so your applications must include code to extract relevant data from the response to return to the user.
|
||
For an example, see the <a href="/get-started-quickstart">Langflow quickstart</a>.</p>
