Both modes use <code>.invoke()</code>, which means the entire response arrives at once after the model finishes generating. Today we fix that — LangBot learns to type its replies one token at a time.</p> <hr> <h2 id="the-problem-waiting-for-the-whole-answer">The problem: waiting for the whole answer</h2> <p>Every interaction so far has the same rhythm:</p> https://pythonflow.com/posts/langbot-day-6-output-parsers/ Mon, 22 Jun 2026 07:00:00 +0100alicandonmez90@gmail.com (flowfelis) https://pythonflow.com/posts/langbot-day-6-output-parsers/ <p><strong>Recap:</strong> On Day 5, LangBot started returning typed objects — every response is now a <code>LangBotResponse</code> with <code>.message</code>, <code>.mood</code>, and <code>.confidence</code>. That is great when you need structured metadata. But structured output is not always the right tool. Sometimes you just want a clean string. Sometimes you want a parsed list. Today we add output parsers — lightweight LCEL components that transform raw <code>AIMessage</code> output into exactly the shape you need.</p>
