High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fine-tune LLMs with reinforcement learning using TRL?▼

You can fine-tune LLMs with reinforcement learning using TRL by running guided SFT or DPO training workflows. This enables efficient end-to-end alignment of HuggingFace models with human preferences.

What is the difference between SFT, DPO, PPO, and GRPO for preference alignment?▼

SFT handles supervised instruction tuning, DPO optimizes offline preference alignment, while PPO and GRPO enable online RL pipelines. TRL supports all these workflows for multi-stage language model alignment.

Can I use HuggingFace Transformers for reward-model training and online RL?▼

Yes, TRL works directly with HuggingFace Transformers to enable reward-model training and online RL. This integration allows seamless optimization of models for human-aligned behavior within existing ML pipelines.

Do I need supervised fine-tuning before running PPO or GRPO workflows?▼

TRL supports scalable multi-stage workflows, meaning you can run SFT for instruction tuning before applying PPO or GRPO for online RL. This staged approach ensures stable reinforcement learning from human feedback.

What's the best way to align language models with human preferences end-to-end?▼

The best way to align language models with human preferences is using TRL's RLHF pipelines. These support instruction tuning, reward-model training, and both offline and online RL for comprehensive preference alignment.

When should I choose DPO over PPO for RLHF pipelines?▼

Choose DPO for offline preference alignment without separate reward modeling, and PPO for online RL pipelines requiring active reward-model training. TRL supports both approaches for flexible human preference alignment.
