Evaluating a Reward Model Strategy for a New Chatbot

A development team is tasked with aligning a new chatbot to be helpful and harmless. Instead of building a reward model from the ground up, they opt to use a large, state-of-the-art, publicly available language model to score the chatbot's responses.

The primary reason this strategy is effective is that the pre-existing model has been specifically trained and fine-tuned on the exact same dataset and objectives as the new model being developed.
