<p>The <strong>Batch Run</strong> component runs a language model over <em>each row of one text column</em> in a <a class="" href="/data-types#table"><code>Table</code></a>, and then returns a new <code>Table</code> with the original text and an LLM response.
|
||
The output contains the following columns:</p>
|
||
<ul>
|
||
<li class=""><code>text_input</code>: The original text from the input <code>Table</code></li>
|
||
<li class=""><code>model_response</code>: The model's response for each input</li>
|
||
<li class=""><code>batch_index</code>: The 0-indexed processing order for all rows in the <code>Table</code></li>
|
||
<li class=""><code>metadata</code> (optional): Additional information about the processing</li>
|
||
</ul>
|
||
<h2 class="anchor anchorTargetStickyNavbar_Vzrq" id="use-the-batch-run-component-in-a-flow">Use the Batch Run component in a flow<a href="#use-the-batch-run-component-in-a-flow" class="hash-link" aria-label="Direct link to Use the Batch Run component in a flow" title="Direct link to Use the Batch Run component in a flow" translate="no"></a></h2>
|
||
<p>If you pass the <strong>Batch Run</strong> output to a <a class="" href="/parser"><strong>Parser</strong> component</a>, you can use variables in the parsing template to reference these keys, such as <code>{text_input}</code> and <code>{model_response}</code>.
|
||
This is demonstrated in the following example.</p>
|
||
<p><img decoding="async" loading="lazy" alt="A batch run component connected to OpenAI and a Parser" src="/assets/images/component-batch-run-19c94fbb0646b2731b37013b84dff1f6.png" width="4000" height="2728" class="img_ev3q"></p>
|
||
<ol>
|
||
<li class="">
|
||
<p>Connect any language model component to a <strong>Batch Run</strong> component's <strong>Language model</strong> port.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Connect <code>Table</code> output from another component to the <strong>Batch Run</strong> component's <strong>DataFrame</strong> input.
|
||
For example, you could connect a <strong>Read File</strong> component with a CSV file.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>In the <strong>Batch Run</strong> component's <strong>Column Name</strong> field, enter the name of the column in the incoming <code>Table</code> that contains the text to process.
|
||
For example, if you want to extract text from a <code>name</code> column in a CSV file, enter <code>name</code> in the <strong>Column Name</strong> field.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Connect the <strong>Batch Run</strong> component's <strong>Batch Results</strong> output to a <strong>Parser</strong> component's <strong>DataFrame</strong> input.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Optional: In the <strong>Batch Run</strong> <a class="" href="/concepts-components#component-menus">component menu</a>, enable the <strong>System Message</strong> parameter, click <strong>Close</strong>, and then enter an instruction for how you want the LLM to process each cell extracted from the file.
|
||
For example, <code>Create a business card for each name.</code></p>
|
||
</li>
|
||
<li class="">
|
||
<p>In the <strong>Parser</strong> component's <strong>Template</strong> field, enter a template for processing the <strong>Batch Run</strong> component's new <code>Table</code> columns (<code>text_input</code>, <code>model_response</code>, and <code>batch_index</code>):</p>
|
||
<p>For example, this template uses three columns from the resulting, post-batch <code>Table</code>:</p>
|
||
<div class="ch-codeblock not-prose" data-ch-theme="github-dark"><div class="ch-code-wrapper ch-code" data-ch-measured="false"><code class="ch-code-scroll-parent"><br><div><span class="ch-code-line-number">_<!-- -->10</span><div style="display:inline-block;margin-left:16px"><span>record_number: {batch_index}, name: {text_input}, summary: {model_response}</span></div></div><br></code></div></div>
|
||
</li>
|
||
<li class="">
|
||
<p>To test the processing, click the <strong>Parser</strong> component, click <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-play lf-inline-icon" aria-hidden="true" focusable="false" role="presentation"><polygon points="6 3 20 12 6 21 6 3"></polygon></svg> <strong>Run component</strong>, and then click <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-text-search lf-inline-icon" aria-hidden="true" focusable="false" role="presentation"><path d="M21 6H3"></path><path d="M10 12H3"></path><path d="M10 18H3"></path><circle cx="17" cy="15" r="3"></circle><path d="m21 19-1.9-1.9"></path></svg> <strong>Inspect output</strong> to view the final <code>Table</code>.</p>
|
||
<p>You can also connect a <strong>Chat Output</strong> component to the <strong>Parser</strong> component if you want to see the output in the <strong>Playground</strong>.</p>
