A Google DeepMind article examines RLHF's operational bottleneck: gathering large volumes of high-quality human preference annotations is slow, expensive and hard to scale, limiting how fast advanced models can be aligned. The authors evaluate whether RLAIF—using an off-the-shelf LLM to generate preference ratings—can match or exceed human feedback on three text generation domains: summarization, helpful dialogue, and harmless dialogue.
