An important characteristic of a model is "stability." Stability means that small changes in input produce small changes in output.

Stability is important for predictability. For instance, suppose you want to make a customer support portal. You add a bot hoping that it will guide the user to the desired workflow. You test the bot by asking it a bunch of variations of questions, probably with some RLHF. But then when it goes to production, people will start asking it variations of questions that you didn't test (guaranteed). What you want ideally, is that it will map the variants to the best workflow that matches what the customer wants. Second best would be to say "I don't know." But what we have are bots who will just generate some crazy off-the-wall crap, and no way to prevent it.
