FAQPage Schema

How does RLHF align language models with human preferences?▼

RLHF aligns language models with human preferences by collecting preference data, training a reward model to score outputs, and applying policy optimization techniques like PPO or DPO to produce safer, more helpful responses.

What is the difference between PPO and DPO for policy optimization?▼

PPO optimizes a policy against a trained reward model, while DPO skips explicit reward modeling by directly aligning the policy with preference data. This Skill supports both PPO and DPO for direct alignment workflows.

What are the steps to build an end-to-end RLHF pipeline?▼

An end-to-end RLHF pipeline involves training a baseline SFT model, collecting and labeling human preference data, training a reward model, and running PPO or DPO optimization to obtain an aligned policy ready for deployment.

Can I use direct alignment methods without training a separate reward model?▼

Yes, direct alignment methods like DPO allow you to apply preference data directly to policy optimization without training a separate reward model. This Skill supports direct-alignment workflows alongside traditional PPO pipelines.

Do I need supervised fine-tuning before applying human feedback optimization?▼

Yes, you should train a baseline SFT model first. The RLHF workflow progresses from supervised fine-tuning through preference data collection and reward modeling to final PPO or DPO policy optimization.

How do I collect and label preference data for reward modeling?▼

Preference data collection involves gathering human feedback on model outputs to label which responses are preferred. This Skill provides workflows for preference data collection and labeling to support subsequent reward modeling and policy optimization.
