title: Many small models vs. one big model
body: <p>I am currently implementing kind of a questionnaire with a chatbot and use LUIS to interpret the answers. This questionnaire is divided into segments of maybe 20 questions.</p>
  
  <p>Now the following question came to mind: Which option is better?</p>
  
  <ol>
  <li>I make one LUIS model per question. Since these questions can include implicit subquestions (i.e. "Do you want to pay all at once or in rates" could include a "How high should these rates be?") I end up with maybe 3-5 intents per question (including <code>None</code>).</li>
  <li>I can make one model per segment. Let's assume that this is possible and fits in the 80 intents per model.</li>
  </ol>
  
  <p>My first intuition was to think that the first alternative is better since this should be way more robust. When there are only 5 intents to choose from, then it may be easier to determine the right one. As far as I know, there is no restriction in how many models you can have (...is this correct?).</p>
  
  <p>So here is my question for SO: What other benefits/drawbacks are there and is there maybe an option that is objectively the best?</p>
