# Why can GPT give different answers to the same prompt?

I sometimes run the same prompt through GPT twice and get noticeably different wording, details, or recommendations. Is that mostly down to randomness, or can changes in [conversation history](https://answers.mindstick.com/qa/117027/how-can-you-maintain-conversation-history-and-context-across-multiple-chat-messages-in-a-net-application), model selection, or system instructions explain the difference?

When you need a dependable result, what do you check first: the prompt, the chat context, or the model settings?
