# Why Can the Same AI Prompt Produce Different Answers on Repeated Runs?

I’m testing an AI assistant with the same wording and settings, but the responses sometimes differ in their examples, details, or even the main recommendation. Is that expected, or does it suggest that something about the model or its context is changing between runs?

For people doing **repeatable AI prompt testing**, what should be held constant—model version, chat history, temperature, or something else—before treating a change in output as meaningful?
