        <p style="text-align:left;">2. <b>Batch Size:</b> Adjust the batch size for processing very long documents (e.g., 500 pages)</p>
        <p style="text-align:left;">3. <b>T5_Model_Checkpoint:</b> Choose the model checkpoint (e.g., "t5-large", "t5-base", "t5-small"). Smaller models require less memory.</p>
