RLHF vs RLAIF：关于AI应如何学习偏好的争论

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-31 02:23

本文探讨了两种使大型语言模型（LLM）与人类偏好保持一致的主要方法：基于人类反馈的强化学习（RLHF）和基于AI反馈的强化学习（RLAIF）。虽然预训练和指令调优能建立通用能力，但偏好优化对于教会模型在多个有效选项中选择“最佳”响应至关重要。RLHF依赖人类判断来对模型输出进行评分和排序，而RLAIF则使用另一个AI模型来提供这些偏好信号，这可能是一种更具可扩展性的方法。 AI

影响阐明了在LLM训练中，人类和AI驱动的偏好信号之间的权衡。

RLHF vs RLAIF：谁应教会人工智能“好”是什么样的？

<p>A large language model trained on the internet is exceptionally good at one thing: predicting the next token. Feed it “The capital of Tamil Nadu is” and it completes the sentence with “Chennai.” This is pretraining, and it gives the model remarkable capabilities. It learns gra…
