Why does ChatGPT sometimes give different answers to the same question?

I’ve noticed that if I ask ChatGPT the same question multiple times, the answers are not always exactly the same. Sometimes the explanation changes slightly, or the level of detail is different. I recently came across something called Nestr where multiple AI responses are shown first before giving a final answer. I’m wondering if approaches like this actually improve consistency, or if variation is just a normal part of how these models work. submitted by /u/InitialOk8252 [link] [comments]
