Pfupiso
It can improve agreement with collected preferences, but does not guarantee truthful, safe, or universally preferred answers.
Kudzika Kwakadzika
A pretrained language model predicts plausible text, but plausible is not the same as helpful, honest, or safe. A common RLHF pipeline addresses these goals in stages. First, supervised fine-tuning teaches the model to follow instructions using human-written example answers. Next, humans compare pairs of model responses to the same prompt and pick the better one; these comparisons train a separate reward model that scores any response. Finally, the language model is optimized with reinforcement learning to produce responses the reward model rates highly. A penalty regularizes deviation from a reference policy; it does not eliminate exploitation of reward-model errors. RLHF was central to making ChatGPT-style assistants usable.

Muenzaniso wemubairo unodzidziswa pazvido zvevanhu kuenzanisa kumhinduro dzezvibodzwa, zvichipa chiratidzo icho mutemo unosimudzira uchipokana.
What does a KL-divergence penalty against a reference policy aim to regularize in an RLHF objective?
The penalty discourages large policy shifts. It is not proof that the reward model cannot be exploited or that generated answers are correct.
