FAQPage Schema
How do I fine-tune a language model with reinforcement learning?▼

You can fine-tune a language model with reinforcement learning by using TRL workflows like SFT, PPO, or GRPO to align model outputs with human preferences. This Skill provides step-by-step guides for training and reward modeling.

What is the best way to train a reward model for human preferences?▼

Training a reward model for human preferences involves using TRL techniques to predict human choices and apply them during reinforcement learning. This Skill explains how to build reward models and integrate them into online RL methods.

Does TRL support both online and offline reinforcement learning methods?▼

TRL supports online reinforcement learning methods like PPO, GRPO, RLOO, and OnlineDPO, alongside supervised fine-tuning and offline preference optimization. This Skill covers these workflows to help align language models with specific tasks.

Can I use TRL to fine-tune models for summarization and translation tasks?▼

You can use TRL to fine-tune language models for summarization, translation, and reasoning tasks by aligning them with human preferences. This Skill demonstrates how to apply TRL training workflows to improve performance on these specific use cases.

Do I need to know reinforcement learning to use TRL for language model alignment?▼

Using TRL for language model alignment requires knowledge of reinforcement learning and reward modeling to effectively apply techniques like PPO and GRPO. This Skill provides the necessary guides to navigate these concepts and execute training workflows.

What's the difference between SFT and PPO workflows in TRL?▼

SFT uses supervised learning for initial task adaptation, while PPO uses reinforcement learning to optimize model outputs against a reward model. This Skill outlines when to use each TRL workflow to achieve desired alignment and performance results.
